Ajax Question

Ajax request to php only works once per pageload

I have seen a few of these questions post on here but none of them are working for me. I have a favourite button that i would like my users to press to favourite things. The ajax request is working just fine and the favourite gets stored in the database but i can only use it once then i have to refresh the page to fav/unfav the item. The code for the button is:

<div id="fav-icon">
<?php
// Function checks if user has fav'd the item.
$isFav = favourite($user->id) ? 'un-fav' : 'fav';
?>
<i id="<?php echo $item->id; ?>" class="<?php echo $isFav; ?>"><span class="font-12 fa fa-heart"></span></i>
</div>


Jquery/Ajax

$('.fav').click(function(e){
var con = $(this).attr('id');
$.ajax({
url: 'fav.php',
type: 'POST',
async: true,
data:{
'fav' : con
},
success:function(){
$('#fav-icon').load(document.URL + ' #fav-icon');
}
});
});

$('.un-fav').click(function(e){
var con = $(this).attr('id');
$.ajax({
url: 'fav.php',
type: 'POST',
async: true,
data:{
'fav' : con
},
success:function(){
$('#fav-icon').load(document.URL + ' #fav-icon');
}
});
});


So this works but only once! I have tried a couple of different functions to try make this work including:

$('.fav').live('click', function(e) {


Can anyone tell me where i am going wrong and the correct method to get my button to work multiple times?

Answer

Use $(document).on() click event

$(document).on('click','.fav', function(e) { 
...
});
