Answer 1

After getting the element as jQuery object via other means than its class, then

(通过其他方式获取元素作为jQuery对象，然后)

var className = $('#sidebar div:eq(14)').attr('class');

should do the trick.

(应该做的伎俩。)

For the ID use .attr('id') .

(对于ID，请使用.attr('id') 。)

If you are inside an event handler or other jQuery method, where the element is the pure DOM node without wrapper, you can use:

(如果您在事件处理程序或其他jQuery方法中，其中元素是没有包装器的纯DOM节点，则可以使用：)

this.className // for classes, and
this.id // for IDs

Both are standard DOM methods and well supported in all browsers.

(两者都是标准的DOM方法，并且在所有浏)
