推荐答案

如果页面上发生的 DOM 操作暂时导致元素无法访问，就会发生这种情况.考虑到这些情况，您可以尝试在循环中多次访问该元素，然后最终抛出异常.

This can happen if a DOM operation happening on the page is temporarily causing the element to be inaccessible. To allow for those cases, you can try to access the element several times in a loop before finally throwing an exception.

试试这个来自 darrelgrainger.blogspot.com 的优秀解决方案:

public boolean retryingFindClick(By by) {
    boolean result = false;
    int attempts = 0;
    while(attempts < 2) {
        try {
            driver.findElement(by).click();
            result = true;
            break;
        } catch(StaleElementException e) {
        }
        attempts++;
    }
    return result;
}
