问题描述：

我正在使用Selenium Webdriver自动化网页.我无法使用简单元素定位器方法在模式弹出窗口中单击按钮.

I am automating a webpage using Selenium Webdriver. I am not able to click a button a modal pop up window using simple element locator method.

示例:

打开www.walmart.com
在搜索框中输入电视.
选择一些电视，然后单击添加到购物车"
现在出现了一个弹出窗口，其中有签出"按钮.我需要点击此结帐"按钮.

我尝试了switchTo()窗口句柄，尝试了switchTo()框架，但没有任何效果.

I tried switchTo() windowhandle, I tried switchTo() frame but nothing worked.

答

该网站运行缓慢，存在加载问题.因此，我建议您对每个findElement使用显式等待.我编写了以下脚本，效果很好

This website is very slow and has loading issue. So, I suggest you to use Explicit wait for each findElement. I have written the following script and works perfectly

WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();        

driver.get("http://www.walmart.com/");
WebDriverWait wait = new WebDriverWait(driver, 20);
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("[placeholder='Search']")))
        .sendKeys("TV");
driver.findElement(By.cssSelector(".searchbar-submit.js-searchbar-submit")).click();
wait.until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.cssSelector("#tile-container>div>a>img")))
        .get(0).click();        
wait.until(ExpectedConditions.elementToBeClickable(By.id("WMItemAddToCartBtn"))).click();
wait.until(ExpectedConditions.elementToBeClickable(By.id("PACCheckoutBtn"))).click();
