使用selenium处理弹出窗口

Question

我有一种情况,点击链接网页打开一个弹出窗口.弹出窗口打开后,焦点位于弹出窗口中,并禁用主窗口.我无法将控件转移到弹出窗口.请查看以下代码.

driver.findElement(By.linkText("Click me")).click();// when this line of code is reached then a popup window opens.

System.out.println("After Clicking me"); // After the popup window opens this line of code is never executed.

我无法将控件从父窗口传输到弹出窗口.我知道以下命令.

driver.switchTo().window("popup window");

但它没有多大帮助.请帮我.

Answer 1

这是我需要使用以下弹出窗口时关闭它然后返回主窗口的代码.当然,为了这个答案的目的,它已被简化.它保持原始窗口(主要)的句柄,因此它可以在其他窗口之间产生差异.

它需要一个显式的WebDriverWait,因为我在开发期间确实遇到了代码在窗口实际打开之前运行的问题,所以这可能不是一个理想的条件,

function manipulatePopUp(final WebDriver driver, final WebDriverWait wait) {
    final String mainWindowHandle = driver.getWindowHandle();
    driver.findElement(By.id("linkThatOpensPopUp")).click();

    wait.until(new ExpectedConditions<Boolean>() {
        @Override
        public Boolean apply(WebDriver d) {
            return (d.getWindowHandles().size() != 1);
        }
    });

    for (String activeHandle : driver.getWindowHandles()) {
        if (!activeHandle.equals(mainWindowHandle)) {
            driver.switchTo().window(activeHandle);
        }
    }

    driver.close();
    driver.switchTo().window(mainWindowHandle);
}

Answer 2

driver.findElement(By.linkText("Click me")).click(); //当到达这行代码时,会打开一个弹出窗口.

System.out.println("点击我之后"); //弹出窗口打开后,这行代码永远不会执行.

从不执行代码行,因为进程正在等待处理弹出窗口.

getWindowHandles()在这种情况下正常工作.

例:

//handle of the master window before clicking the link
String master = driver.getWindowHandle();

driver.findElement(By.linkText("Click me")).click();

//logic for waiting for the popup, checking the size to become greater than 1 or breaking after sometime to avoid the infinite loop.
int timeCount = 1;

do
{
   driver.getWindowHandles();
   Thread.sleep(200);
   timeCount++;
   if ( timeCount > 50 ) 
   {
       break;
   }
}
while ( driver.getWindowHandles().size == 1 );

//Assigning the handles to a set
Set<String> handles = driver.getWindowHandles();
//Switching to the popup window.
for ( String handle : handles )
{
    if(!handle.equals(master))
    {
         driver.switchTo().window(handle);
    }
}

现在驱动程序切换到弹出窗口.如果弹出窗口有框架,则需要在识别框架中的元素之前切换到框架.
