JavaScript通过className获取子元素 [英] JavaScript get child elements by className

问题描述

我在Javascript中写了以下一行：

I have written the following line in Javascript:

var eleCategory = document.getElementById("cmbCategory");

现在我想查找包含的所有 elementbyClassName 在 eleCategory 元素中。

Now I want to find all elementbyClassName contained in the eleCategory element.

是否可以使用类似的内容？

Is it possible with something like this?

 var eleChild = eleCategory.getElementByClassName("autoDropdown");

如何获取父元素的子元素？

How can I get the child element of the parent element?

推荐答案

getElementsByClassName 尚未在所有浏览器中实现。例如， Niels的解决方案在IE中不起作用。但是，其他人已经创建了自己的实施; John Resig撰写了关于他的博客的文章

getElementsByClassName hasn't been implemented in all browsers. Niels' solution, for instance, doesn't work in IE. However, others have created their own implementation; John Resig has a write-up on his blog
