Jquery: How to select more than one element

if you have two elements like:

$(‘#name’).add(‘#address’)

Jquery: How to work with same class name elements event

Assumed that you have some links with same class. like:

<a class=”delete_user” href=”#”>delete</a>
<a class=”delete_user” href=”#”>delete</a>
<a class=”delete_user” href=”#”>delete</a>
.
.
.
<a class=”delete_user” href=”#”>delete</a>

on click event you want to delete the user info from database table. then just add a new attribute “user_id” here “user_id: is the primary key of “user” table. like:

<a user_id=”1″ class=”delete_user” href=”#”>delete</a>
<a user_id=”2″ class=”delete_user” href=”#”>delete</a>
<a user_id=”3″ class=”delete_user” href=”#”>delete</a>
.
.
.
<a user_id=”10″ class=”delete_user” href=”#”>delete</a>

then the Jquery code is:

(function(){

//DELETE USER
$(“.delete_user”).click(function(){
var user_id = $(this).attr(‘user_id’);
//here you delete operation using user_id
});

})();
