警报处理 + Java + webdriver [英] Alert Handling + Java + webdriver

问题描述

我正在尝试使用 switch 来提醒并执行操作，但我遇到了错误.

I am trying to use switch to alert and perform an action but i face error.

现在真正的问题是当我将下面的代码放在 try 中时，它可以完美运行.我的意思是它完美地处理了警报.但是当我在没有尝试的情况下使用相同的代码时，它会抛出以下异常

Now the real issue is when i put the below code in try,catch it works perfectly. i mean it handles the alert perfectly. But when i use the same without try, catch code it throws the below exception

  Alert alert = driver.switchTo().alert();
            String AlertText = alert.getText();
System.out.println(javascriptconfirm.getText());
            alert.accept();

请找出下面的错误

No alert is present (WARNING: The server did not provide any stacktrace information)

推荐答案

这个想法是，当您处理警报时，您必须首先检查警报是否存在.我会使用这种方法:

The idea is when you deal with alerts you have to check whether alert is present first. I would use this approach:

public boolean isAlertPresent() {

  boolean presentFlag = false;

  try {

   // Check the presence of alert
   Alert alert = driver.switchTo().alert();
   // Alert present; set the flag
   presentFlag = true;
   // if present consume the alert
   alert.accept();

  } catch (NoAlertPresentException ex) {
   // Alert not present
   ex.printStackTrace();
  }

  return presentFlag;

 }

这里你可以得到详细信息也不要忘记逐步调试以了解出现/不出现警报的步骤.希望这对您有所帮助.
