jQuery autocomplete RegExp for highlight words

Question

I'm using renderItem to highlight words from search input, but i need on some way to ignore last spaces.

For example

var term = '123';

result

123 456

456 123

But if

var term = '123 ';

Than will highlight only

123 456

456 123

And i need to highlight 123 everywhere or in some way to ignore spaces in term

This is function.

_renderItem: function (ul, item) {
    var newlabel = String(item.value).replace(
            new RegExp(this.term,"ig"),
            "<strong>$&</strong>");
    return $("<li></li>")
        .data("item.autocomplete", item)
        .append("<div>" + newlabel + "</div>")
        .appendTo(ul);
}
