selenium - 如何在selenium webdriver中将控制从子窗口切换到父窗口？

Question

• 从父窗口我将控件传递给子窗口
• 我正在子窗口中执行操作
• 执行后，从子窗口会再打开一个窗口(Child 第一个子窗口的)。

• 我必须关闭两个子窗口并返回到 父窗口。

  我无法将控件从子窗口切换到父窗口。我已经尝试过下面的代码

   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

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);
