<span class="favorite" id="favorite_x">...
You can either parse out the integer in JS or pass the entire
"favorite_x" string to the PHP script to parse it out there.
$(function(){
$('.favorite').click(function()
{
var fave_id = $(this).attr('id').substr(9);
$.post(
"test.php",
{id: fave_id},
function(data)
{
alert("Data Loaded: " + data);
}
);
});
});
$(function(){
$('.favorite').click(function()
{
$.post(
"test.php",
{id: $(this).attr('id')},
function(data)
{
alert("Data Loaded: " + data);
}
);
});
});
