推荐答案

WebDriver click()模拟与UI的真实用户交互.我将通过向浏览器发送一个本机事件来执行(在大多数浏览器中)，并且必须可见该事件才能单击它.从文档

WebDriver click() simulates real user interaction with the UI. I will be performed (in most browsers) by sending a native event to the browser, and it has to be visible in order to click on it. From the docs

...如果click()是通过发送本地事件(即 大多数浏览器/平台上默认)

...if click() is done by sending a native event (which is the default on most browsers/platforms)

点击某个元素有一些先决条件.元素 必须可见，并且高度和宽度必须大于0.

There are some preconditions for an element to be clicked. The element must be visible and it must have a height and width greater then 0.

另一方面

JavaScript click()

在当前选定框架的上下文中执行JavaScript，或者 窗口.

Executes JavaScript in the context of the currently selected frame or window.

无论WebElement是否可见.这种方法错过了用户交互Selenium试图模拟的想法.

Regardless if the WebElement is visible or not. This approach misses the idea of user interaction Selenium tries to simulate.
