如何在硒的webdriver點擊一個鏈接

Question

伊瑪嘗試點擊所有目前在HTML

http://www.flipkart.com/在這種電子元件 - 按類別>商店 - >

下面

是HTML

的樣品部分

<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> 

使用以下

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(); 

當IAM點擊iam運行代碼它正在進行，直到我= 12，直到惠普後，它是 拋出一個錯誤。有83個元素出席。我需要點擊並導航回

是否有任何替代方法，而不是href單擊鏈接。

Answer 1

這是給你一個可選的解決方案：

1. 迭代的所有鏈接，並保存在一個列表他們<href>屬性的值。
2. 迭代上一步中生成的列表，並將瀏覽器導航到每個URL。

這樣做，這樣可以確保您的代碼不依賴於你從原來的網頁的DOM閱讀WebElement對象，一旦你收集了所有的網址，您不再需要留在這個網頁上。

步驟＃1：

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

步驟＃2：

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

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

第3步：

迭代lis後，導航到每個網址：

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