alert、confirm、prompt這樣的js對話方塊在selenium webdriveriver中處理十分方便簡潔。以下面html代碼為例：
example.html
<html>
<head>
<title>Alert</title>
</head>
<body>
<input id = "alert" value = "alert" type ="button" onclick = "alert('你好！請按確認繼續！');"/>
<input id = "confirm" value= "confirm" type = "button" onclick = "confirm('確定？');"/>
<inputid = "prompt" value = "prompt" type = "button"onclick = "var name = prompt('請輸入內容:','請輸入
內容'); document.write(name) "/>
</body>
</html>
以上html代碼在頁面上顯示了三個按鈕，點擊他們分別彈出alert、confirm、prompt對話方塊。如果在prompt對話方塊中輸入文字點擊確定之後，將會重新整理頁面，顯示這些文字 。
selenium webdriveriver 處理這些彈層的代碼如下：
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriveriver;
import org.openqa.selenium.firefox.FirefoxDriveriver;
public class Alertpop{
/**
* @author tyf
*/
publicstatic void main(String[] args) {
//TODO Auto-generated method stub
WebDriveriver driver = new FirefoxDriveriver();
Stringurl = "file:///C:/selenium/Example.html";//Example.html檔案所在的路徑
driver.get(url);
//點擊第一個按鈕，輸出對話方塊上面的文字
driver.findElement(By.id("alert")).click();
Alertalert = driver.switchTo().alert();
Stringtext = alert.getText();
System.out.println(text);
alert.dismiss();//關閉alert
//點擊第二個按鈕，輸出對話方塊上面的文字，然後確認
driver.findElement(By.id("confirm")).click();
Alertconfirm = driver.switchTo().alert();
Stringtext1 = confirm.getText();
System.out.println(text1);
confirm.accept();
//點擊第三個按鈕，輸入你的名字，然後點擊確認
driver.findElement(By.id("prompt")).click();
Alertprompt = driver.switchTo().alert();
Stringtext2 = prompt.getText();
System.out.println(text2);
prompt.sendKeys("jarvi");
prompt.accept();
}
}
從以上代碼可以看出driver.switchTo().alert();這句可以得到alert\confirm\prompt對話方塊的對象，然後運用其方法對它進行操作。對話方塊操作的主要方法有：
