Javascript Begins With match regex

Got the following filter function but it isn't working. How should I modify it to match items that begin with the args.SearchString?

function myFilter(item, args) {
    var filterFieldName = columns[$('#filter-select-column').find(':selected').val()]["field"];
    var val = (item[filterFieldName].match("^" + args.searchString + "/i"));
    return val;

Use the RegExp constructor:

var val = (item[filterFieldName].match(new RegExp("^" + args.searchString, "i")));
