如何在selenium WebDriver中将控件从子窗口切换到父窗口？

Question

>

我正在将控件从父窗口传递到子窗口

我正在子窗口中执行操作

执行后，将从子窗口再打开一个窗口（第一个子窗口的子窗口）。

我必须关闭两个子窗口并返回父窗口。

我无法将控件从子窗口切换到父窗口。我已经试用了下面的代码

 String winHandleBefore = _driver.getWindowHandle();
for(String winHandle : _driver.getWindowHandles()){
    _driver.switchTo().window(winHandle);
}

String winHandleAfter = _driver.getWindowHandle();

/在子窗口中执行操作/

driver.close();
_driver.switchTo().window(winHandleBefore);

Answer 1

像这样试试。

1. 关闭第二个子窗口
2. 然后有两个窗口主窗口和第一个子窗口
3. 尝试getWindowhandles（）；它应该返回2个窗口句柄。
4. 从两个窗口句柄中提取主窗口句柄。
5. 使用以上窗口句柄切换回主窗口。

或

Driver.SwitchTo（）.DefaultContent（）；

使用此代码：

 // Get Parent window handle
 String winHandleBefore = _driver.getWindowHandle();
 for (String winHandle : _driver.getWindowHandles()) {
   // Switch to child window
   driver.switchTo().window(winHandle);
 }

// Do some operation on child window and get child window handle.
String winHandleAfter = driver.getWindowHandle();

//switch to child window of 1st child window.
for(String winChildHandle : _driver.getWindowHandles()) {
  // Switch to child window of the 1st child window.
  if(!winChildHandle.equals(winHandleBefore) 
  && !winChildHandle.equals(winHandleAfter)) {
    driver.switchTo().window(winChildHandle);
   }
 }

// Do some operation on child window of 1st child window.
// to close the child window of 1st child window.
driver.close();

// to close the child window.
driver.close();

// to switch to parent window.
driver.switchto.window(winHandleBefore);
