如何找到哪个JavaScript正在更改元素的样式？ [英] How do I find which JavaScript is changing an element's style?

问题描述

我有一个元素通过JavaScript应用样式。我不知道到底在哪里;有没有办法检查Firebug来显示element.style实际来自哪里？

I have an element that's getting styles applied via JavaScript. I'm not sure exactly where; is there a way to check Firebug to show where the "element.style" is actually coming from?

推荐答案

确保它被设置在内联 style 上，而不是样式表规则的结果，您可以使用非标准Mozilla watch（） method：

If you're sure it's being set on the inline style and not as a consequence of a stylesheet rule, you can detect changes using the non-standard Mozilla watch() method:

document.body.style.watch('color', function(name, v0, v1) {
    alert(name+': '+v0+'->'+v1);
});
document.body.style.color= 'red';

您可以将 debugger; 函数，并在Firebug中查找调用堆栈，以查看触发更改的位置。

You can put debugger; in the watcher function and look up the call stack in Firebug to see where the change was triggered.
