Question

想试着点击Html中的所有元素

http://www.flipkart.com/在此电子产品下 - ＆gt;按类别购物 - ＆gt;

下面的

是Html的样本部分

<a class="" data-tracking-id="0_Samsung" href="/mobiles/samsung~brand/pr?sid=tyy,4io&amp;otracker=hp_nmenu_sub_electronics_0_Samsung">Samsung</a>

<a class="" data-tracking-id="0_All Brands" href="/mobiles/pr?sid=tyy,4io&amp;otracker=hp_nmenu_sub_electronics_0_All%20Brands">All Brands</a>


<a class="" data-tracking-id="0_All Brands" href="/laptops/pr?sid=6bo,b5g&amp;otracker=hp_nmenu_sub_electronics_0_All%20Brands">All Brands</a>

我点击下面的

 WebElement ul = driver.findElement(By.id("menu-electronics-tab-0-content"));
       List<WebElement> lis = ul.findElements(By.tagName("li"));
       System.out.println(""+lis.size());
       String[] linksText = new String[lis.size()];
       int index = 0;
       for(WebElement element : lis){

           linksText[index] = element.getText();

        String string = linksText[index];

        if(string.contains(" ")){
            linksText[index]= string.substring(0, string.indexOf(" ")); 
        }

           index++;
       }     
               for(index =0; index < linksText.length; index++){
           String xpath = "//*[contains(@href,'%s')]";
           String y = linksText[index];
                   String xpathOfElement = String.format(xpath, String.valueOf(y));
                      System.out.println("Name 1  "+driver.findElement(By.xpath(xpathOfElement)).getText());
                   driver.manage().timeouts().implicitlyWait(50000, TimeUnit.MILLISECONDS);

                          driver.findElement(By.xpath(xpathOfElement)).click();

当iam运行代码时，它正在进行直到i = 12，直到HP为止抛出一个错误。有83个元素存在。我需要点击并导航回来

除了href之外还有其他方法可以点击链接。

Answer 1

以下是适用于您的可选解决方案：

迭代所有链接，并将其<href>属性的值保存在列表中。
迭代上一步生成的列表，并在浏览器中导航到每个URL。

这样做可确保您的代码不依赖于您从原始网页的DOM中读取的WebElement个对象，并且一旦您收集了所有网址，就不会需要更长时间才能留在这个网页上。

第1步：

在迭代lis之前，请添加ArrayList<String> urls = new ArrayList<String>();

第2步：

替换driver.findElement(By.xpath(xpathOfElement)).click();

使用urls.add(driver.findElement(By.xpath(xpathOfElement)).getAttribute("href"));

第3步：

在迭代lis后，导航到每个网址：

for (String url : urls)
    driver.get("http://www.flipkart.com"+url);
