Delegation: Bind and Is or Live

Delegation: Bind and Is or Live


Hello,
Sorry of this comes across as a silly question but I was wonder which is the better approach (or are they essentially the same thing?). Description - A div called skill-list houses hundreds of drop downs with the class skill-level-selector. When one of these selcts are changed an ajax call is made. Code below --
$('.skill-level-selector').live("change", function(){
$.post(
'someUrl',
{
skillId: this.id.split('-')[2],
level: $(this).val()
},
function(data, textStatus){ }
);
});
---- OR ----
$('#skill-list').bind("change", function (e) {

var target = $(e.target);

if(target.is('.skill-level-selector')){
$.post(
'someUrl',
{
skillId: e.target.id.split('-')[2],
level: target.val()
},
function(data, textStatus){ }
);
}
});
As far as I can see they appear to so the same thing so perhaps the first is a bit more succinct- am I right in that assumption. Also according to the live api page it says change is UNsupported but both of these examples work for me so perhaps it's not fully UNsupported?
Regards,
James.
