动态创建元素上的jQuery（悬停和加载）事件绑定

Question

I am able to bind click event to element with class name keybox . And this element is generated dynamically.

$('body').on('click','.keybox', function(){
// some code here
});

But for same element I tried binding hover and load event using following code:

$('body').on('hover','.keybox', function(){
// some code here
});


$('body').on('load','.keybox', function(){
// some code here
});

....and its not working as expected.

Can someone help with this problem? I want to bind hover and load event to my element with class name keybox and this element is generated dynamically.

Answer 1

Instead of hover, use mouseenter and mouseleave event. Instead of body.load use

$(document).ready(function() {

Answer 2

You can use following approach to bind multiple events and get object information via event object .

$('body').bind('click hover load', '.keybox', function(e){
   if ( e.type === 'hover') {
     // do something
   }
   else if(e.type === 'click') {
    // do something
   }
   ....
});

Make sure you bind events in $(document).ready(function() {} or load javascript just in bottom of html document body.

Since hover is deprecated you should use mouseenter and mouseleave for load you can write using event using on ( load is equivalent to ready ).

 $(function(){ $(document).on('mouseenter', '.keybox', function () { $(this).css('color','red'); }); $(document).on('mouseleave', '.keybox', function () { $(this).css('color','black'); }); $(document).on('click', '.keybox', function () {// click on dynamically loaded events. $(this).css('color','green'); }); $('#btn').click(function() { $('#parent').append("<div class='keybox'>sample1</div>"); $('#parent').append("<div class='keybox'>sample2</div>"); }); });
