jQuery bind() and unbind() – attaching event handlers

element attributes

jQuery bind() function is used to attach one or more event handler to elements, while the unbind() is used to removes an existing event handler from elements.

As of jQuery version 1.7, jQuery on() method is the preferred method rather than jquery bind and unbind for attaching event handlers for selected elements.

bind() :

A basic usage of .bind() is:

$( "#elementID" ).bind( "click", function() {
console.log( "User single clicked" );
$("#elementID").bind("dblclick", function () {
console.log( "User double clicked" );

Alternatively, you can combine the code like following:

click : function(){
console.log( "User single clicked" );
dblclick : function(){
console.log( "User double clicked" );

var message = "Message passed to jQuery!";
$( "#elementID" ).bind( "click", {
msg: message
}, function( event ) {
console.log( event.data.msg );

unbind() :

The unbind() method removes previously attached event handlers from selected elements.

The below example detached the “click” and “dblclick” event from elements with an Id of “elementID”.


As of jQuery version 1.7, jQuery off() methods are preferred method for removing event handlers for selected elements.
