Selenium WebDriver: Unable to Select Element - selenium

Question

<input type="text" id="mobile" name="mobile" placeholder="Mobile Number" maxlength="10" value="" onkeyup="javascript:dispLocMob(this);" onkeydown="javascript:dispLocMob(this);" onchange="javascript:dispLocMob(this);">
Shown above is the element that I'm trying to send keys. I tried by xpath and id and all sorts of selectors, but it throws an error that is shown below:
Unable to locate element: {"method":"xpath","selector":"/html/body/div[3]/div/form/div[2]/div[1]/input"}
Command duration or timeout: 338 milliseconds

Is there something defined in the Web Element that does not let me access the element in my Selenium script?
Any suggestions/advice will be highly appreciated.
Thanks you!

Answer 1

Try as below :-
WebDriverWait wait = new WebDriverWait(driver, 10);
el = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("mobile")));
el.sendKeys("your value");
Note :- Be ensure before finding element that it is not inside any frame or iframe. If it is inside any frame or iframe you need to switch that frame first as :- driver.switchTo().frame("frame name or id")
Hope it will help you...:)

Answer 2

First of all, If you are using xpaths then use relative xpath instead of absolute as slight change in DOM makes absolute xpaths invalid or refer to a wrong element.
Second try using .click(); before .sendkeys();. So your code can be something like
WebElement ele = dvr.findElement(By.id("mobile"));
ele.click();
ele.sendKeys("your string");
Lastly, make sure you do not have any duplicate elements on the page with same property, i.e. id=="mobile". Hope this helps

Answer 3

Please try below code:
If the element is not in any frame:
driver.findElement(By.id("mobile")).sendKeys("");
If the element is inside a frame:
// Switching to the frame
driver.switchTo().frame(<framename>);
driver.findElement(By.id("mobile")).sendKeys("");
driver.switchTo().defaultContent();
Also, please add some wait after launching the page and entering the text. And even if the code is not working, please check whether the element is visible or not using below code:
if(driver.findElement(By.id("mobile")).isDisplayed()) {
// Add the code given above
}
Hope this helps
