Scroll Element into View with Selenium - selenium

Is there any way in either Selenium 1.x or 2.x to scroll the browser window so that a particular element identified by an XPath is in view of the browser? There is a focus method in Selenium, but it does not seem to physically scroll the view in FireFox. Does anyone have any suggestions on how to do this?
The reason I need this is I'm testing the click of an element on the page. Unfortunately the event doesn't seem to work unless the element is visible. I don't have control of the code that fires when the element is clicked, so I can't debug or make modifications to it, so, easiest solution is to scroll the item into view.

Have tried many things with respect to scroll, but the below code has provided better results.
This will scroll until the element is in view:
WebElement element = driver.findElement(By.id("id_of_element"));
((JavascriptExecutor) driver).executeScript("arguments[0].scrollIntoView(true);", element);
Thread.sleep(500);
//do anything you want with the element

You can use the org.openqa.selenium.interactions.Actions class to move to an element.
Java:
WebElement element = driver.findElement(By.id("my-id"));
Actions actions = new Actions(driver);
actions.moveToElement(element);
actions.perform();
Python:
from selenium.webdriver.common.action_chains import ActionChains
ActionChains(driver).move_to_element(driver.sl.find_element_by_id('my-id')).perform()

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("javascript:window.scrollBy(250,350)");
You may want to try this.

If you want to scroll on the Firefox window using the Selenium webdriver, one of the ways is to use JavaScript in the Java code. The JavaScript code to scroll down (to bottom of the web page) is as follows:
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.scrollTo(0, Math.max(document.documentElement.scrollHeight, document.body.scrollHeight, document.documentElement.clientHeight));");

Targeting any element and sending down keys (or up/left/right) seems to work also. I know this is a bit of a hack, but I'm not really into the idea of using JavaScript to solve the scrolling problem either.
For example:
WebElement.sendKeys(Keys.DOWN);

In Selenium we need to take the help of a JavaScript executor to scroll to an element or scroll the page:
je.executeScript("arguments[0].scrollIntoView(true);", element);
In the above statement element is the exact element where we need to scroll. I tried the above code, and it worked for me.
I have a complete post and video on this:
http://learn-automation.com/how-to-scroll-into-view-in-selenium-webdriver/

webElement = driver.findElement(By.xpath("bla-bla-bla"));
((JavascriptExecutor)driver).executeScript("arguments[0].scrollIntoView();", webElement);
For more examples, go here. All in Russian, but Java code is cross-cultural :)

I found that the bounding rect of my element was not correct, leading to the browser scrolling well off the screen. However, the following code works rather well for me:
private void scrollToElement(WebElement webElement) throws Exception {
((JavascriptExecutor)webDriver).executeScript("arguments[0].scrollIntoViewIfNeeded()", webElement);
Thread.sleep(500);
}

You can use this code snippet to scroll:
C#
var element = Driver.FindElement(By.Id("element-id"));
Actions actions = new Actions(Driver);
actions.MoveToElement(element).Perform();
There you have it

This worked for me:
IWebElement element = driver.FindElements(getApplicationObject(currentObjectName, currentObjectType, currentObjectUniqueId))[0];
((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].scrollIntoView(true);", element);

Use the driver to send keys like the pagedown or downarrow key to bring the element into view. I know it's too simple a solution and might not be applicable in all cases.

From my experience, Selenium Webdriver doesn't auto scroll to an element on click when there are more than one scrollable section on the page (which is quite common).
I am using Ruby, and for my AUT, I had to monkey patch the click method as follows;
class Element
#
# Alias the original click method to use later on
#
alias_method :base_click, :click
# Override the base click method to scroll into view if the element is not visible
# and then retry click
#
def click
begin
base_click
rescue Selenium::WebDriver::Error::ElementNotVisibleError
location_once_scrolled_into_view
base_click
end
end
The 'location_once_scrolled_into_view' method is an existing method on WebElement class.
I apreciate you may not be using Ruby but it should give you some ideas.

The Ruby script for scrolling an element into view is as below.
$driver.execute_script("arguments[0].scrollIntoView(true);", element)
sleep(3)
element.click

Selenium 2 tries to scroll to the element and then click on it. This is because Selenium 2 will not interact with an element unless it thinks that it is visible.
Scrolling to the element happens implicitly so you just need to find the item and then work with it.

Sometimes I also faced the problem of scrolling with Selenium. So I used javaScriptExecuter to achieve this.
For scrolling down:
WebDriver driver = new ChromeDriver();
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("window.scrollBy(0, 250)", "");
Or, also
js.executeScript("scroll(0, 250);");
For scrolling up:
js.executeScript("window.scrollBy(0,-250)", "");
Or,
js.executeScript("scroll(0, -250);");

This is a repeated solution with JavaScript, but with an added waiting for element.
Otherwise ElementNotVisibleException may appear if some action on the element is being done.
this.executeJavaScriptFunction("arguments[0].scrollIntoView(true);", elementToBeViewable);
WebDriverWait wait = new WebDriverWait(getDriver(), 5);
wait.until(ExpectedConditions.visibilityOf(elementToBeViewable));

I have used this way for scrolling the element and click:
List<WebElement> image = state.getDriver().findElements(By.xpath("//*[contains(#src,'image/plus_btn.jpg')]"));
for (WebElement clickimg : image)
{
((JavascriptExecutor) state.getDriver()).executeScript("arguments[0].scrollIntoView(false);", clickimg);
clickimg.click();
}

def scrollToElement(element: WebElement) = {
val location = element.getLocation
driver.asInstanceOf[JavascriptExecutor].executeScript(s"window.scrollTo(${location.getX},${location.getY});")
}

Something that worked for me was to use the Browser.MoveMouseToElement method on an element at the bottom of the browser window. Miraculously it worked in Internet Explorer, Firefox, and Chrome.
I chose this over the JavaScript injection technique just because it felt less hacky.

You may want to visit page Scroll Web elements and Web page- Selenium WebDriver using Javascript:
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
FirefoxDriver ff = new FirefoxDriver();
ff.get("http://toolsqa.com");
Thread.sleep(5000);
ff.executeScript("document.getElementById('text-8').scrollIntoView(true);");
}

If you think other answers were too hacky, this one is too, but there is no JavaScript injection involved.
When the button is off the screen, it breaks and scrolls to it, so retry it... ¯\_(ツ)_/¯
try
{
element.Click();
}
catch {
element.Click();
}

In most of the situation for scrolling this code will work.
WebElement element = driver.findElement(By.xpath("xpath_Of_Element"));
js.executeScript("arguments[0].click();",element);

JAVA
Try scroll to element utilize x y position, and use JavascriptExecutor with this is argument: "window.scrollBy(x, y)".
Following import:
import org.openqa.selenium.WebElement;
import org.openqa.selenium.JavascriptExecutor;
First you need get x y location the element.
//initialize element
WebElement element = driver.findElement(By.id("..."));
//get position
int x = element.getLocation().getX();
int y = element.getLocation().getY();
//scroll to x y
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.scrollBy(" +x +", " +y +")");

I am not sure if the question is still relevant but after referring to scrollIntoView documentation from https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView.
The easiest solution would be
executor.executeScript("arguments[0].scrollIntoView({block: \"center\",inline: \"center\",behavior: \"smooth\"});",element);
This scrolls the element into center of the page.

Javascript
The solustion is simple:
const element = await driver.findElement(...)
await driver.executeScript("arguments[0].scrollIntoView(true);", element)
await driver.sleep(500);

The default behavior of Selenium us to scroll so the element is barely in view at the top of the viewport. Also, not all browsers have the exact same behavior. This is very dis-satisfying. If you record videos of your browser tests, like I do, what you want is for the element to scroll into view and be vertically centered.
Here is my solution for Java:
public List<String> getBoundedRectangleOfElement(WebElement we)
{
JavascriptExecutor je = (JavascriptExecutor) driver;
List<String> bounds = (ArrayList<String>) je.executeScript(
"var rect = arguments[0].getBoundingClientRect();" +
"return [ '' + parseInt(rect.left), '' + parseInt(rect.top), '' + parseInt(rect.width), '' + parseInt(rect.height) ]", we);
System.out.println("top: " + bounds.get(1));
return bounds;
}
And then, to scroll, you call it like this:
public void scrollToElementAndCenterVertically(WebElement we)
{
List<String> bounds = getBoundedRectangleOfElement(we);
Long totalInnerPageHeight = getViewPortHeight(driver);
JavascriptExecutor je = (JavascriptExecutor) driver;
je.executeScript("window.scrollTo(0, " + (Integer.parseInt(bounds.get(1)) - (totalInnerPageHeight/2)) + ");");
je.executeScript("arguments[0].style.outline = \"thick solid #0000FF\";", we);
}

I've been doing testing with ADF components and you have to have a separate command for scrolling if lazy loading is used. If the object is not loaded and you attempt to find it using Selenium, Selenium will throw an element-not-found exception.

If nothing works, try this before clicking:
public void mouseHoverJScript(WebElement HoverElement) {
String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
((JavascriptExecutor) driver).executeScript(mouseOverScript, HoverElement);
}

In Java we can scroll by using JavaScript, like in the following code:
driver.getEval("var elm = window.document.getElementById('scrollDiv'); if (elm.scrollHeight > elm.clientHeight){elm.scrollTop = elm.scrollHeight;}");
You can assign a desired value to the "elm.scrollTop" variable.

A solution is:
public void javascriptclick(String element)
{
WebElement webElement = driver.findElement(By.xpath(element));
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].click();", webElement);
System.out.println("javascriptclick" + " " + element);
}

Selenium Python - element click intercepted [duplicate]

I am trying to make some tests using selenium based Katalon Studio. In one of my tests I have to write inside a textarea. The problem is that I get the following error:
...Element MyElement is not clickable at point (x, y)... Other element would receive the click...
In fact my element is place inside some other diva that might hide it but how can I make the click event hit my textarea?
Element ... is not clickable at point (x, y). Other element would receive the click" can be caused for different factors. You can address them by either of the following procedures:
Element not getting clicked due to JavaScript or AJAX calls present
Try to use Actions Class:
WebElement element = driver.findElement(By.id("id1"));
Actions actions = new Actions(driver);
actions.moveToElement(element).click().build().perform();
Element not getting clicked as it is not within Viewport
Try to use JavascriptExecutor to bring the element within Viewport:
JavascriptExecutor jse1 = (JavascriptExecutor)driver;
jse1.executeScript("scroll(250, 0)"); // if the element is on top.
jse1.executeScript("scroll(0, 250)"); // if the element is at bottom.
Or
WebElement myelement = driver.findElement(By.id("id1"));
JavascriptExecutor jse2 = (JavascriptExecutor)driver;
jse2.executeScript("arguments[0].scrollIntoView()", myelement);
The page is getting refreshed before the element gets clickable.
In this case induce some wait.
Element is present in the DOM but not clickable.
In this case add some ExplicitWait for the element to be clickable.
WebDriverWait wait2 = new WebDriverWait(driver, 10);
wait2.until(ExpectedConditions.elementToBeClickable(By.id("id1")));
Element is present but having temporary Overlay.
In this case induce ExplicitWait with ExpectedConditions set to invisibilityOfElementLocated for the Overlay to be invisible.
WebDriverWait wait3 = new WebDriverWait(driver, 10);
wait3.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("ele_to_inv")));
Element is present but having permanent Overlay.
Use JavascriptExecutor to send the click directly on the element.
WebElement ele = driver.findElement(By.xpath("element_xpath"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", ele);
I assume, you've checked already that there is no any other component overlapping here (transparent advertisement-iframes or some other component of the DOM => seen quite often such things in input/textfield elements) and, when manually (slowly) stepping your code, it's working smoothly, then ajax calls might cause this behaviour.
To avoid thread.sleep, try sticking with EventFiringWebDriver and register a handle to it.
(Depending on your application's techstack you may work it for Angular, JQuery or wicket in the handler, thus requiring different implementations)
(Btw: This approach also got me rid of "StaleElementException" stuff lots of times)
see:
org.openqa.selenium.support.events.EventFiringWebDriver
org.openqa.selenium.support.events.WebDriverEventListener
driveme = new ChromeDriver();
driver = new EventFiringWebDriver(driveme);
ActivityCapture handle=new ActivityCapture();
driver.register(handle);
=> ActivityCapture implements WebDriverEventListener
e.g. javascriptExecutor to deal with Ajax calls in a wicket/dojo techstack
#Override
public void beforeClickOn(WebElement arg0, WebDriver event1) {
try {
System.out.println("After click "+arg0.toString());
//System.out.println("Start afterClickOn - timestamp: System.currentTimeMillis(): " + System.currentTimeMillis());
JavascriptExecutor executor = (JavascriptExecutor) event1;
StringBuffer javaScript = new StringBuffer();
javaScript.append("for (var c in Wicket.channelManager.channels) {");
javaScript.append(" if (Wicket.channelManager.channels[c].busy) {");
javaScript.append(" return true;");
javaScript.append(" }");
;
;
;
javaScript.append("}");
javaScript.append("return false;");
//Boolean result = (Boolean) executor.executeScript(javaScript.toString());
WebDriverWait wait = new WebDriverWait(event1, 20);
wait.until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver driver) {
return !(Boolean) executor.executeScript(javaScript.toString());
}
});
//System.out.println("End afterClickOn - timestamp: System.currentTimeMillis(): " + System.currentTimeMillis());
} catch (Exception ex) {
//ex.printStackTrace();
}
}
As #DebanjanB said, your button (or another element) could be temporarily covered by another element, but you can wait and click it even if you don't know which element is covering the button.
To do this, you can define your own ExpectedCondition with the click action:
public class SuccessfulClick implements ExpectedCondition<Boolean> {
private WebElement element;
public SuccessfulClick(WebElement element) { //WebElement element
this.element = element;
}
#Override
public Boolean apply(WebDriver driver) {
try {
element.click();
return true;
} catch (ElementClickInterceptedException | StaleElementReferenceException | NoSuchElementException e) {
return false;
}
}
}
and then use this:
WebDriverWait wait10 = new WebDriverWait(driver, 10);
wait10.until(elementToBeClickable(btn));
wait10.until(new SuccessfulClick(btn));
Try Thread.Sleep()
Implicit - Thread.Sleep()
So this isn’t actually a feature of Selenium WebDriver, it’s a common feature in most programming languages though.
But none of that matter.
Thread.Sleep() does exactly what you think it does, it’s sleeps the thread. So when your program runs, in the majority of your cases that program will be some automated checks, they are running on a thread.
So when we call Thread.Sleep we are instructing our program to do absolutely nothing for a period of time, just sleep.
It doesn’t matter what our application under test is up to, we don’t care, our checks are having a nap time!
Depressingly though, it’s fairly common to see a few instances of Thread.Sleep() in Selenium WebDriver GUI check frameworks.
What tends to happen is a script will be failing or failing sporadically, and someone runs it locally and realises there is a race, that sometimes WedDriver is losing. It could be that an application sometimes takes longer to load, perhaps when it has more data, so to fix it they tell WebDriver to take a nap, to ensure that the application is loaded before the check continues.
Thread.sleep(5000);
The value provided is in milliseconds, so this code would sleep the check for 5 seconds.
I was having this problem, because I had clicked into a menu option that expanded, changing the size of the scrollable area, and the position of the other items. So I just had my program click back on the next level up of the menu, then forward again, to the level of the menu I was trying to access. It put the menu back to the original positioning so this "click intercepted" error would no longer happen.
The error didn't happen every time I clicked an expandable menu, only when the expandable menu option was already all the way at the bottom of its scrollable area.

Selenium click not work

Help me please.
Selenium does not click on element and element is clickable(selenium does not generate exception).
I try use Id, css, xpath locators, nothing did not help me.
What should i do to decide my problem?
Java code example.
WebElement sector = webDriver.findElement(By.id("sector-1"));
sector.click();
After click system must open this page
Seems that you try to interact with object inside a <svg> element. If so, you cannot manage it's child elements simply using click() method.
Try this instead:
WebElement svgObject = driver.findElement(By.xpath("//polygon[#id='sector-1:canvas']"));
Actions builder = new Actions(driver);
builder.click(svgObject).build().perform();
Use below XPath :
WebElement sector = webDriver.findElement(By.xpath("//g[#id='sector-1']/polygon"));
sector.click();
OR
WebElement sector = webDriver.findElement(By.xpath("//polygon[#id='sector-1:canvas']"));
sector.click();
I decide my problem.
WebDriverWait wait = new WebDriverWait(webDriver, 10);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//*[#id=\"sector-2:canvas\"]")));
WebElement svgObject = webDriver.findElement(By.xpath("//*[#id=\"sector-2:canvas\"]"));
Actions builder = new Actions(webDriver);
builder.click(svgObject).build().perform();

Selenium WebDriver resize textarea

Using Selenium webdriver with Java how can I resize a textarea/
I want to expand the textarea by dragging the right-bottom corner of the element.
I have tried something like this, but it doesnt change the element at all
new Actions(webdriver).dragAndDropBy(element, height, width).perform()
I do not have anything to test this issue on, but i'm guessing the reason the dragAndDropBy method you used didn't work because it would not be clicking the bottom-right corner of the element. I believe you would need something like:
Actions action = new Actions(driver);
action.moveToElement(toElement, xOffset, yOffset); //moves to bottom right corner
action.clickAndHold();
action.moveByOffset(xOffset, yOffset);
action.release();
action.perform();
The offsets depend on the size of the text area you mentioned. You can look into more on the Action class at: http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/interactions/Actions.html. Hopefully this helps.
I think the reason your code was not working because build() method was not included can you try this and tell if its now working-
new Actions(webdriver).dragAndDropBy(element, height, width).build().perform();
This can be done with JavaScriptExecutor interface. JavaScriptExecutor is an interface which provides mechanism to execute Javascript through selenium webdriver with the help of this you can change rows and cols attributes of textarea hence textarea can be resize with it. Hope this will help you out -
public static void main(String[] args) {
ProfilesIni profile = new ProfilesIni();
FirefoxProfile a = profile.getProfile("default");
WebDriver driver = new FirefoxDriver(a);
driver.get("http://localhost/testfolder/textarea.html");
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("document.getElementById('textarea').setAttribute('rows', '30')");
js.executeScript("document.getElementById('textarea').setAttribute('cols', '50')");
}
just locate textarea element with an element locator then set 'rows' and 'cols' attribute values.
I hope this helps you.

Test dynamically loaded content with Selenium Web Driver

I am working on a system that has a web based frontend that I am testing with Selenium. On one page the content is dynamically loaded when scrolling down (maybe you know that from Facebook's friend-list), because it is one of the requirements.
Scrolling down with Selenium Webdriver (I use Chrome) should be no problem via Javascript. But there is a problem with the dynamically added content. How can I make the Webdriver find those elements?
I tried the following to scroll down until no more content is loaded:
int oldSize = 0;
int newSize = 0;
do {
driver.executeScript("window.scrollTo(0,document.body.scrollHeight)");
newSize = driver.findElementsBy(By.cssSelector("selector").size();
} while(newSize > oldSize);
But though the page scrolls down the first time and some now content is loaded correctly, they will not be found by the drivers' findElementsBy(By) function.
Has someone ever faced this problem?? I'd be very glad if someone could help me figuring a solution for that!
Regards, Benjamin
I would recommend using WebDriverWait with ExpectedConditons.
//scroll down with Javascript first
WebDriverWait wait = new WebDriverWait(driver, 30);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("selector")));
//interact with your element
element.click()
Take a look at the guidance provided by Selenium Official page:
http://seleniumhq.org/docs/04_webdriver_advanced.html
try using fluent wait in particular. The main feature is:
An implementation of the Wait interface that may have its timeout and polling interval configured on the fly.
Each FluentWait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as NoSuchElementExceptions when searching for an element on the page.
public WebElement fluentWait(final By locator){
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(5, TimeUnit.SECONDS)
.ignoring(NoSuchElementException.class);
WebElement foo = wait.until(
new Function<WebDriver, WebElement>() {
public WebElement apply(WebDriver driver) {
return driver.findElement(locator);
}
}
);
return foo; } ;
The method described returns you web element you can operate with.
So the approach be the following:
1) you need to find the selectors of elements you expect to be rendered after scrolling
e.g.
String cssSelector = "blablabla"
2) scroll down with js
3)
WebElement neededElement = fluentWait(cssSelector);
neededElement.click();
//neededElement.getText().trim();
you can get more info about fluent wait here
I think the problem is waiting for the dynamic content to finish loading. Try to wait 3 seconds just before findElementsBy? In C# the code would be Thread.Sleep(3000);
