Java

对于简单警报：

 Alert simpleAlert = driver.switchTo().alert();
String alertText = simpleAlert.getText();
System.out.println("Alert text is " + alertText);
simpleAlert.accept();

对于提示警报：

Alert promptAlert  = driver.switchTo().alert();
String alertText = promptAlert.getText();
System.out.println("Alert text is " + alertText);
//Send some text to the alert
promptAlert.sendKeys("Accepting the alert");
Thread.sleep(4000); //This sleep is not necessary, just for demonstration
promptAlert.accept();

对于确认警报：

Alert confirmationAlert = driver.switchTo().alert();
String alertText = confirmationAlert.getText();
System.out.println("Alert text is " + alertText);
confirmationAlert.accept();

另一种方法是将代码包装在 try-catch 中：

try{
   // Your logic here.
} catch(UnhandledAlertException e){
  Alert alert = driver.switchTo().alert();
  alert.accept();
}

// Continue.
