切换回父窗口并对父级执行操作会引发JavaScript错误

Question

尝试自动化电子商务网站SnapDeal

我在控制台中收到此错误：

从子窗口切换到父窗口并在父窗口上重新尝试某些操作。

    //Logging in to SnapDeal using Facebook.

    SnapDeal.findElement(By.xpath("//div[@id='fbUserLogin']")).click();
    String pWindow = SnapDeal.getWindowHandle();
    for (String winHandle : SnapDeal.getWindowHandles()) 
    {
           //Switch to child window 
           SnapDeal.switchTo().window(winHandle);
    }

    WebElement FBLoginID = SnapDeal.findElement(By.xpath("//input[@id='email']"));
    JavascriptExecutor js = (JavascriptExecutor)SnapDeal;
    js.executeScript("arguments[0].value='YourEmailID';", FBLoginID);

    WebElement FBPass = SnapDeal.findElement(By.xpath("//input[@id='pass']"));
    JavascriptExecutor jE = (JavascriptExecutor)SnapDeal;
    jE.executeScript("arguments[0].value='YourPassword';", FBPass);
    SnapDeal.findElement(By.xpath("//button[@id='loginbutton']")).click();
    SnapDeal.findElement(By.xpath("//button[@name='__CONFIRM__']")).click();
    Thread.sleep(5000);

    //Switching back to parent window
    SnapDeal.switchTo().window(pWindow);

    //logging out of the application in the parent window post switching 
    WebElement WelCome = SnapDeal.findElement(By.xpath("//span[contains(.,'Welcome')]"));
    WebElement LogOut = SnapDeal.findElement(By.xpath("//a[contains(.,'Logout')]"));
    Actions mousehover = new Actions(SnapDeal);
    mousehover.moveToElement(WelCome).perform();
    Thread.sleep(5000);
    mousehover.click(LogOut).perform();

非常感谢您解决此问题的任何帮助。

使用SET首先存储父窗口和子窗口，然后迭代它。我没有尝试过你的代码，但是这种使用SET和迭代器的逻辑必须适合你。
