jquery Gets the class value implementation code

There is a div, and I want to get its ID or class value.

So I can navigate to the div and take the attr method to get its value:

If you say: There is a section of HTML code:

The code is as follows

Copy Code

<div class= "comment" id= ">" <div class= "Comment_detail" style= "display:block; "> <div class= "comment_my" ><textarea class= "Comment_text" style=; "></textarea></div> <div class= "Comment_text_bottom" style= "display:none; "> <div class= "comment_emotion" ><a href= "javascript:void (0)" class= "Comment_emotion_button" > Www.111cn.net Facial Expression </a> <div class= "Comment_emotion_detail" style= "display:none; "> </div> </div> <div class= "Comment_publish" ><input class= "Submit" type= "submit" value= "comments" ></div> </div> </div> <div class= "Comment_bar" ><a href= "javascript:void (0)" class= "Comment_click" ></a></div> </div>

If I want to locate from submit and get the ID of the div at comment, then I can do this:

The ID value is:

The code is as follows	Copy Code
$ (". Submit"). Parent (). Parent (). Parent (). attr (' id ');

The value is: 22;

The class value is:

The code is as follows	Copy Code
$ (". Submit"). Parent (). Parent (). Parent (). attr (' class ')

The value is:
Comment

Gets the class value and sets the

The code is as follows	Copy Code
<div class= "div" > <span class= "Span" ></span> <a href= "javascrip:void (0)" class= "a" > </a> </div> $ ("Div.div"). Hover (function () { $ (this). Next ("Span.span"). Show (); },function () { $ (this). Next ("Span.span"). Hide (); });

If you want to take a property value of a class element, we just

The code is as follows	Copy Code
$ (". Foo"). Click (function () {Alert ($ (this). attr ("value"));

You can write it.
