1.警告框

程式6-17示範效果:打開含有警告框的網頁，等待2秒後輸出警告框資訊，點選确認後退出。含有警告框的網頁HTML代碼如下所示。

public static void main(String[] args) throws InterruptedException {
WebDriver driver = WebDriverUtils.getWebDriver();
String url = "https://www.leichuangkj.com/alert.html";
driver.get(url);
Thread.sleep(2000);
//切換到警告框
Alert javascriptAlert = driver.switchTo().alert();
System.out.println(javascriptAlert.getText());
javascriptAlert.accept();
