在JavaScript中以编程方式触发onmouseover事件 [英] Trigger onmouseover event programmatically in JavaScript

问题描述

有没有办法在纯JavaScript中以编程方式触发 onmouseover 事件？或者从 onmouseover 事件中提取该方法直接调用它？

Is there a way to programmatically trigger the onmouseover event in plain JavaScript? or "extract" the method from the onmouseover event to call it directly?

例如

<div id="bottom-div" onmouseover="myFunction('some param specific to bottom-div');">
    <div id="top-div" onmouseover="????????"></div>
</div>

top-div高于bottom-div，所以 onmouseover 不会在bottom-div中被触发。我需要一种方法来调用 myFunction（'某些param特定于bottom-div'）; 来自top-div

top-div is above bottom-div, so the onmouseover won't get fired in bottom-div. i need a way of calling myFunction('some param specific to bottom-div'); from top-div

推荐答案

你会这样做：

document.getElementById('top-div').onmouseover();

但是，正如评论中所提到的，在被视为问题之前，它值得测试。

However, as mentioned in the comments, it would be worth testing before being considered an issue.
