Selenium web驱动程序-循环内等待(Java)
我见过很多等待Selenium Web driver的方法(such as this one) (专门针对Java)。然而，在这里应用这些方法似乎不起作用。
我试图通过循环哈希表中的值来测试用户查询结果。我在下面的代码中尝试了两种方法:等待document.readyState和加载按类选择的项。然而，看起来列表似乎是在创建all，而没有为完成元素刷新留出时间。

}我有时会遇到以下错误，这实际上可能是在元素更新时发生的。我正在寻找一个可以解决这个问题的解决方案：
Exception in thread "main" org.openqa.selenium.StaleElementReferenceException: The element reference of <div class="list-card-price"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed
