陈旧元素引用：元素未附加到页面文档 [英] stale element reference: element is not attached to the page document

问题描述

我有列表，每个部分下都有多个链接。每个部分都有相同的链接，我需要点击每个部分下的特定链接。我写了下面的代码但是当它执行时它给了我陈旧元素引用：元素没有附加到页面文档错误。

I have list which has multiple links under each section. Each section has same links I need to click a particular link under each section. I have written the below code but when it executes it gives me stale element reference: element is not attached to the page document error.

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结构如下所示

This is the HTML structure is as below

<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

推荐答案

提供异常的行是什么？

原因是因为您引用的元素已从DOM结构中删除

The reason for this is because the element to which you have referred is removed from the DOM structure

我在使用IEDriver时遇到了同样的问题。原因是因为javascript在我引用之后再次加载元素所以我的日期引用指向一个未存在的对象，即使它在UI上是正确的。我使用了以下解决方法。

I was facing the same problem while working with IEDriver. The reason was because javascript loaded the element one more time after i have referred so my date reference pointed to an unexisting object even if it was right their on UI. I used the following workaround.

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();
}

看看它是否可以帮到你！
