jQuery autocomplete on class, how to get id

I have been working on this a while and can't seem to get anywhere. Basically I have the autocomplete on a bunch of inputs by class, but I need to get the specific inputs id to build the object to post the ajax (I have to use POST for this project not GET).

$(".input_autocomplete").autocomplete({
source: function( request, response ) {
// here is where I get the hash from local storage,
// reference the id and build the object
// tried this.id, $(this).prop('id'), no luck
$.ajax({
url: '/somepath/filename.htm',
contentType: 'application/json',
dataType: 'json',
type: 'POST',
data: JSON.stringify(obj),
success: function(json) {
return {
label: item.label,
value: item.label
}
},
error: function() {
// error handling
}
}); // ajax
} // source
});

Answer

Try:

$(this.element).prop("id");

or:

this.element[0].id;

Inside of the source callback, this refers to the widget instance. In order to get the element the widget is attached to, you should use this.element, which is a jQuery object.
