Selenium Button Click() or Submit()? - selenium

Question

Need help on following scenario(using Java):
Doing it manually like this: after filling in some info in a parent page, clicking Continue button on it,
<INPUT TYPE='button' VALUE='Continue' onClick='sendForm()'>
A child window(UserConfirmationPage) pops up with those info from its parent window, clicking the Continue button on the child page, posting the data to server.
<FORM NAME='userConf' ACTION='user.jsp' METHOD='post'>
Do you want to continue?<BR>
<INPUT TYPE='button' VALUE='Continue' onClick='createUser()'>
</FORM>
However, when I do it using Selenium Web Driver, on the parent page,
btnContinue.submit()
a child page pops up with those info from parent page just like what I got when I do it manually but parent does not exist any more. While using
btnContinue.click()
a blank child page is opened without getting any info from parent page and it also complains "session is lost".
I also tried:
JavascriptExecutor jse = (JavascriptExecutor) driver;
jse.executeScript("arguments[0].click();",btnContinue);
and
new Actions(driver).moveToElement(driver.findElement(By.xpath("//input[#value='Continue']"))).click().perform();
but nothing works.
It seems that neither Submit() nor Click() could simulate what was done manually. Any idea?
Thanks a lot in advance!

Answer 1

You did not specify the language, so I assume you're using JAVA:
// since new tab has been opened - need to switch to this tab
// get a list of the currently open windows
Set<String> allTabs = driver.getWindowHandles();
// save the window handle for the current window
String programTab = driver.getWindowHandle();
// switching to the Save tab
String saveTab = ((String) allTabs.toArray()[1]);
driver.switchTo().window(saveTab);
// set timeout
// Click button
driver.findElement(By.id("buttonId")).click();
// set timeout
// switch back to the program tab
driver.switchTo().window(programTab);

Try this it is simplest and easiest code which help you to understand Parent and child scenario.
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://demo.guru99.com/popup.php");
driver.findElement(By.xpath("html/body/p/a")).click();
// return the parent window name as a String
String parentWindow=driver.getWindowHandle();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
// Pass a window handle to the other window
for(String childWindow: driver.getWindowHandles())
{
System.out.println("child");
//switch to child window
driver.switchTo().window(childWindow);
//find an element and print text of it
WebElement textLabel=driver.findElement(By.xpath("html/body/div[1]/h2"));
System.out.println(" text: "+textLabel.getText());
driver.close();
}
System.out.println("Come to parent window");
//switch to Parent window
driver.switchTo().window(parentWindow);
//find an element and print text of it
WebElement logotext=driver.findElement(By.xpath("html/body/div[1]/h2"));
System.out.println("text: "+logotext.getText());
driver.close();
}
