java - 需要帮助使用 webdriver 和 java 识别灯箱上的控件

Question

我正在尝试自动化网站的登录流程。当我单击“登录”时，会弹出一个灯箱，并且我的脚本无法识别弹出窗口中的元素。该网站是 www.zillow.com，当我单击右上角的“登录”链接时，就会发生这种情况。

我尝试使用 JavascriptExecutor、等待和其他一些方法，但无法识别。这里需要帮助。谢谢!我得到的错误如下。

public class Trial {

    public static void main(String [] args){

        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.zillow.com");
        driver.manage().window().maximize();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        driver.findElement(By.xpath("//*[@id='login_opener']/span")).click();
        driver.findElement(By.xpath("//*[@id='email']")).sendKeys("abcde");
        driver.findElement(By.xpath("//*[@id='password']']")).sendKeys("abcde");
    }
}

我发现您的 Xpath 格式错误。我稍微修改了你的代码，效果很好

 WebDriver driver = new FirefoxDriver();
                driver.get("http://www.zillow.com");
                driver.manage().window().maximize();
                driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
                driver.findElement(By.xpath("//span[contains(text(),'Sign in')]")).click();
                driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
                driver.findElement(By.xpath("//input[@id='email']")).sendKeys("abcde");
                driver.findElement(By.xpath("//input[@id='password']")).sendKeys("abcde");

我更改了以下 xpath，并在单击“登录”按钮后引入了一个隐式等待

1. //span[contains(text(),'Sign in')] 标识登录按钮。
2. //输入[@id='email']来标识电子邮件文本框
3. //输入[@id='password']识别密码文本框
