Question

我正在使用driver.findelements（By.xpath（“// *））;要检索页面上的所有元素，但是，在IE9 / IE10上，我得到一个陈旧的元素异常。怎么做我处理了吗？请帮帮我。

错误列在下面：

所以看起来，从堆栈跟踪看，你的驱动程序只等待15MS。那太短了。尝试：

wd.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

至少在IE上运行时。这就是说我担心这个问题实际上是构建IE驱动程序的一个缺陷。看看这个帖子：

这个和其他非常痛苦的hackarounds这个问题...

我怀疑IE驱动程序受到支持。

使用Java，如何处理WebDriver中的“陈旧元素异常”？
