Is there any way to trim (remove leading/trailing spaces) the input entered by a user into a jQuery auto-completing text `<input>` box before it is matched against the list of names:values? I currently have a textbox in which users are meant to enter names. The names are then matched against a list of name:value pairs by jQuery:

```
<script type="text/javascript">

var resources = [
               <?php 
                    foreach($data['Resource'] as &$row){
                        $Name = $row['Forename']." ".$row['Surname'];  
                        echo "{";
                        echo "  label:'$Name',";
                        echo "  value:'$row[EmployeeNumber]'";
                        echo "},";
                    }
                 ?>
                ];

    jQuery(function(){
        jQuery('#Resource').autocomplete({
            source: resources,
            focus: function(event, ui) {
                jQuery('#Resource').val(ui.item.label);
                return false;
            },          
            select: function(event, ui) {
                jQuery('#Resource').val(ui.item.label);
                jQuery('#EmployeeNumber').val(ui.item.value);
                return false;
            }
        });
    }); 
</script>

```

My problem is that if the user enters a name that matches one in the `resources` map, but with spaces after it, it won't be matched and thus no value will be assigned to the input. I would like for trailing spaces at least (if not also leading spaces) to be ignored on this mapping if possible.

Additionally, would it be possible to add a default value for the input box if no map is found?

**EDIT:**

As an aside, is it possible to have a no-match entry shown in the drop-down autocomplete box if the user types something that doesn't match? Apologies for the after-question edit.
