推荐答案

我遇到了同样的问题，找不到任何解决方案。提出一个解决方案，并将其发布在这里，希望这可以帮助有同样问题的人。我创建了一个类来处理陈旧元素，具体取决于它们的类型，cssselector，id等，并简单地调用它就像我任何其他页面对象一样。

I ran across this same problem and could not find any solutions. Came up with a solution and posting it here, hope this helps someone with the same problem. I created a class to handle stale elements depending on their type, cssselector, id, etc and simply call it like I would any other page object.

public void StaleElementHandleByID (String elementID){
int count = 0;
boolean clicked = false;
while (count < 4 || !clicked){
    try {
       WebElement yourSlipperyElement= driver.findElement(By.id(elementID));
       yourSlipperyElement.click(); 
       clicked = true;
     } catch (StaleElementReferenceException e){
       e.toString();
       System.out.println("Trying to recover from a stale element :" + e.getMessage());
       count = count+1;
     }     
}

我建议你只在你知道的元素上使用它导致WebDriver出现问题。

I'd recommend only using this on elements you know cause problems for WebDriver.
