java - “StaleElementReferenceException : Element not found in the cache - perhaps the page has changed since it was looked up

Question

我想找出页面上损坏的链接。

但是当我尝试单击第二个链接(以检查页面上损坏的链接)时，我在第二次迭代中遇到错误

StaleElementReferenceException: Element not found in the cache - perhaps the page has changed since it was looked up Command duration or timeout: 47 milliseconds"

这是我的代码:

    WebElement element =driver.findElement(By.tagName("a"));
    List<WebElement> links = driver.findElements(By.tagName("a"));
   System.out.println(links.size());

   for (int index=0; index<links.size(); index++ ) { 
       links.get(index).click();
       driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
       driver.getTitle();
       driver.navigate().back(); 

       } 

有人可以告诉我我犯了一个错误吗？

Answer 1

我认为您无法在页面上存储元素，浏览，然后返回使用它们。每次到达新页面时，您都需要再次选择它们(有点刷新)。

尝试这样的事情

   for (int index=0; index<links.size(); index++ ) {
      links = driver.findElements(By.tagName("a")); 
      links.get(index).click();
      driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
      driver.getTitle();
      driver.navigate().back(); 
   }
