推荐答案
Firefox只有一个click（）函数用于表单元素，如按钮。但是，您可以直接调用onClick函数;您可以将行更改为
Firefox only has a click() function for form elements such as buttons. However, you can call the onClick function directly; you can change the line to
document.getElementById('mylabel').onclick();
这适用于firefox或IE（但请注意，它要求该功能实际存在，你知道在这个例子中它确实如此）。
This works in firefox or IE (but note that it requires that the function actually exists, which you know it does in this example).
还要注意你实际上并没有模拟对该元素的点击（例如，如果有其他东西这样的话点击会做，比如也可以作为点击容器，它们不会发生）。你只是获得了一个点击运行的功能，并直接运行它。因此，对于您需要模拟点击的所有情况，它都不是解决方案。
Also note that you aren't actually simulating a click on that element (so, for example, if there were other things that such a click would do, such as also act as a click on the container, they won't happen). You're just getting the function that would run on a click, and running it directly. So it's not a solution for all situations where you need to simulate a click.
