Selenium xpath没有这样的元素异常,即使它在firepath中工作

Question

这是我使用Firebug检查元素时的样子

当我在xpath中尝试相同的语法时,它选择结果页面2.我在selenium IDE中尝试了相同的方法并单击了find,它在执行代码时选择结果页面2.我正在接受No Such Element异常

Xpath语法: //a[contains(@href,'/jobs?q=qa+engineer&l=Renton%2C+WA&start=10')]/span[contains(@class,'pn')][text()='2']

public void jobSearch(){
        WebDriver driver= new FirefoxDriver();
        driver.get("https://www.indeed.com");
        driver.findElement(By.id("what")).sendKeys("QA Engineer");
        driver.findElement(By.id("where")).clear();
        driver.findElement(By.id("where")).sendKeys("Seattle,WA");
        driver.findElement(By.id("fj")).click();
        driver.manage().timeouts().implicitlyWait(25, TimeUnit.SECONDS);

        driver.findElement(By.xpath("//a[contains(@href,'/jobs?q=qa+engineer&l=Renton%2C+WA&start=10')]/span[contains(@class,'pn')][text()='2']")).click();

感谢您的宝贵时间和宝贵的建议.

Answer 1

实际上有3个错误:

1. 最大的错误,脚本无法找到下一页的可见选项.在给定的截图中,运行给定代码的结果.这就是脚本无法找到元素的原因.

Selenium Webdriver脚本仅适用于Visible Area

方案:

添加步骤以向下滚动 网页

JavascriptExecutor jse = (JavascriptExecutor) driver;
jse.executeScript("window.scrollBy(0,1000)", "");

2. Xpath不是一般化的.它用于获取在2num页面放置的URL .因此改变如下:

   //div[@class='pagination']//span[text()='2']

3. 有一些中断,如弹出,基于地区的网址.所以编写代码就像给定消除未来错误一样:

   public void jobSearch()   {
   
   
       try{
           WebDriver driver= new FirefoxDriver();
           driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
           driver.manage().window().maximize();
           driver.get("https://www.indeed.com");
           try
           {
               //Here region based URL gets open so remove it if it is directly open www.indeed.com
               driver.findElement(By.linkText("www.indeed.com")).click();
           }
           catch (Exception e)
           {
   
           }
           driver.findElement(By.id("what")).sendKeys("QA Engineer");
           driver.findElement(By.id("where")).clear();
           driver.findElement(By.id("where")).sendKeys("Seattle,WA");
           driver.findElement(By.id("fj")).click();
           try
           {
               // After this one pop up gets open so close it
               driver.findElement(By.xpath("//button[@id='prime-popover-close-button']/span")).click();
           }
           catch (Exception e)
           {
   
           }
           //pageDown(driver.findElement(By.id("searchCount")), 2);
           JavascriptExecutor jse = (JavascriptExecutor) driver;
           jse.executeScript("window.scrollBy(0,1000)", "");
           //driver.findElement(By.xpath("//a[contains(@href,'/jobs?q=qa+engineer&l=Renton%2C+WA&start=10')]/span[contains(@class,'pn')][text()='2']")).click();
           driver.findElement(By.xpath("//div[@class='pagination']//span[text()='2']")).click();
           // Now continue you code here
       }
       catch (Exception e)
       {
           e.printStackTrace();
       }   }
