onchange 事件<div>当我无法控制元素何时更改时

Question

I have a div element on a page that has other divs added to it when certain events happen.我在页面上有一个 div 元素，当某些事件发生时，该元素添加了其他 div。 I do not know when these events happen, how they are triggered and how the other divs are added to the main div (its external so I have no idea whats happening all I have access to is the div).我不知道这些事件何时发生，它们是如何触发的，以及其他 div 如何添加到主 div（它是外部的，所以我不知道发生了什么，我只能访问 div）。

How would I "monitor" for changes to the main div so an event is triggered whenever a new div is added ?我将如何“监视”主 div 的更改，以便在添加新 div 时触发事件？ I know I can use setInterval (which is what I'm doing now), but I really do not want to use it unless absoluley necessary.我知道我可以使用 setInterval （这就是我现在正在做的），但我真的不想使用它，除非绝对必要。 I would love to something as simple as form elements do with onchange but I have not found such for divs.我很想使用 onchange 做一些像表单元素一样简单的事情，但我还没有为 div 找到这样的东西。

Example if text is not clear:文本不清晰的示例：

wesite.com/index.html ( the only thing I have access to) wesite.com/index.html（我唯一可以访问的）

<html>
<head></head>
<body>
    <div id="theDiv">
    </div>
</body>
</html>

and at times unknown to me divs get added to that div and it eventually looks like :有时我不知道 div 会被添加到该 div 中，它最终看起来像：

<html>
<head></head>
<body>
    <div id="theDiv">
        <div class="added"><p>Added Div</p></div>
        <div class="added"><p>Added Div</p></div>
        <div class="added"><p>Added Div</p></div>
        <div class="added"><p>Added Div</p></div>
        <div class="added"><p>Added Div</p></div>
    </div>
</body>
</html>

And lets say I set up the event to trigger an alert, in this example I want to see an alert box every time a new div is added so by the time it looks like this I should have seen 5 alert boxes.假设我设置了触发警报的事件，在这个例子中，我想在每次添加新 div 时看到一个警报框，所以当它看起来像这样的时候，我应该看到 5 个警报框。

Sorry if this is difficult to follow..对不起，如果这很难遵循..

The easiest way is to intercept the calls that are adding the children to the DIVs.最简单的方法是拦截将子项添加到 DIV 的调用。 Is this not an option?这不是一个选择吗？
