最近，我将 Selenium 版本从 2.53 升级到 4.1.2，以便能够在 MS EDGE IE11 上测试我们的应用程序。但是，当我们使用简单的 Selenium .clear() 清除任何 TextBox 字段时，我们不断面临问题。虽然，其各自的清除，但也抛出以下异常。
还有其他人在 Selenium-4.1.2 上遇到过类似的问题吗？

期望：我们期望 clear() 应该清除该字段而不引发任何异常。
Recently, I have upgraded my Selenium version from 2.53 to 4.1.2 to enable testing of our application on MS EDGE IE11. But we are continuously facing issue when we are clearing any TextBox field using simple Selenium .clear(). Although, its clearing that respective and but also throwing below exception.
Did anyone else facing similar kind of issues with Selenium-4.1.2 ?
Exception:

这是由于边缘模式驱动程序中的错误
https://github.com/seleniumhq/seleniumhq/selenium/selenium/issues/10488 将使用javascriptexecutor定位和清除输入字段
This is due to a bug in the Edge IE mode driver
https://github.com/SeleniumHQ/selenium/issues/10488
A possible workaround would be to use JavascriptExecutor to locate and clear the input field
invalidelementStateException 表明webelement处于某种状态，在某种状态下无法执行任何操作。几个示例将包括一个单击时被另一个元素遮盖的元素，或者可能在DOM上不可见。
解决方案
始终建议 clear 任何
＆lt; input＆gt;字段您需要诱导 em> 对于元素（ javascript ）to render html dom 单击（） 如下：InvalidElementStateException indicates that a WebElement is in a certain state in which actions cannot be performed with it. A couple of examples would include an element being obscured by another when clicking, or perhaps not being visible on the DOM.
Solution
It is always recommened that to clear any
<input>field you need to induce WebDriverWait to elementToBeClickable() for the element (JavaScript) to render the HTML DOM completely before you invokeclick()as follows:
