jQuery Autocomplete ignore 0 - php

Question

Users enter values like 01234 and 12345. I would like to ignore the 0 when a users enters.
<input name="location" class="input-lg" style="width:100%;" id="location" type="text" size="50" placeholder="<?php echo $this->lang->line('inputhint');?>" />
$(function() {
var availableLocations =
<?php
// print the json array containing all zips
echo $locations;
?>
$("#location").autocomplete({
source: availableLocations,
minLength: 3,
focus: function (event, ui){
$('#location').val(ui.item.value);
return false;
},
select: function (event, ui){
$('#location').val(ui.item.value); // display the selected text
$('#locationid').val(ui.item.key); // save selected id to hidden input
return false;
},
change: function (event, ui){
// write value to hidden field
$( "#locationid" ).val( ui.item? ui.item.key : 0 );
return false;
}
});
});
Is there any way to do that? I tried a lot of things, but I can not handle it. Any idea?

The following is untested, but it works something like this:
$("#location").autocomplete({
source: function(request, response) {
// manipulate your search term
var yourTerm = parseInt(request.term);
// run a filter function on your data...
var filteredArray = $.map(availableLocations, function(item) {
// or whatever your matching rule is....
if( item.startsWith(yourTerm)){
return item;
} else{
return null;
}
});
// return the filtered values
response(filteredArray);
}
});
