我的列表在每个部分下都有多个链接。每个部分都有相同的链接，我需要单击每个部分下的特定链接。我已经编写了下面的代码，但是当它执行时它给了我 stale element reference: element is not attach to the page document 错误。

这是我的代码:

public static void main(String[] args) throws InterruptedException 
{
    WebDriver driver = new ChromeDriver();
    driver.navigate().to("url......");
        driver.findElement(By.id("Login1_txtEmailID")).sendKeys("hourbank5@....com");
    driver.findElement(By.id("Login1_txtPassword")).sendKeys("Testing1*");
    driver.findElement(By.id("Login1_btnLogin")).click();
    List<WebElement> LeftNavLinks=driver.findElements(By.xpath("//*[@id='sliding-navigation']//a"));
    Thread.sleep(1000);
    String ben="Benefit Status";
    String[] linkTexts = new String[LeftNavLinks.size()];
    int i = 0;
    for (WebElement e : LeftNavLinks) 
    {   
        linkTexts[i] = e.getText();
        System.out.print(i+" " + linkTexts[i]+"\n");
        if(linkTexts[i].equals(ben))
        {
            String BenefitStatLi="//*[@id='sliding-navigation']/li[%s]/a";
            System.out.print(i+" " + linkTexts[i]+"\n");
                driver.findElement(By.xpath(String.format(BenefitStatLi,i))).click();
            driver.findElement(By.xpath("//* [@id='divContentHolder']/div[1]/a[1]")).click();
        }
        i++;
    }
}

}

这是HTML结构如下

<div id="ucAdminMenu_divMenu">
  <ul id="sliding-navigation">
    <li class="sliding-element">
      <a href=" ">Claims Status</a>
    </li>
    <li class="sliding-element">
      <a href=" ">Eligibility Status</a>
    </li>
    <li class="sliding-element">
      <h3>Section-1</h3>
    </li>
    <li class="sliding-element">
      <a href=" ">Forms and Documents</a>
    </li>
    <li class="sliding-element">
      <a href=" HourBank.aspx?id=002">Hour Bank</a>
    </li>
    <li class="sliding-element">
      <h3>Section-2</h3>
    </li>
    <li class="sliding-element">
      <a href=" ">Benefit Status</a>
    </li>
    <li class="sliding-element">
      <a href=" ">Forms and Documents</a>
    </li>
    <li class="sliding-element">
      <h3>Section-3</h3>
    </li>
    <li class="sliding-element">
      <a href=" ">Forms and Documents</a>
    </li>
    <li class="sliding-element">
      <h3>Testing Fund</h3>
    </li>
    <li class="sliding-element">
      <a href=" ">Benefit Status</a>
    </li>
    <li class="sliding-element">
      <a href=" ">Order ID Card</a>
    </li>
  </ul>
</div>

错误跟踪是:

    Exception in thread "main" 
org.openqa.selenium.StaleElementReferenceException: stale element 
reference: element is not attached to the page document

最佳答案

给出异常的行是什么？？

这是因为您所引用的元素已从 DOM 结构中删除

我在使用 IEDriver 时遇到了同样的问题。原因是javascript在我引用后又加载了一次元素，所以我的日期引用指向一个不存在的对象，即使它就在UI中。我使用了以下解决方法:

try {
    WebElement date = driver.findElement(By.linkText(Utility.getSheetData(path, 7, 1, 2)));
    date.click();
}
catch(org.openqa.selenium.StaleElementReferenceException ex)
{
    WebElement date = driver.findElement(By.linkText(Utility.getSheetData(path, 7, 1, 2)));
    date.click();
}

看看能不能帮到你!
