A simple, effective multi-dimensional row filtering script

rowFilter.js

var filter;

(function () {
    filter = function (searchBox, targetClass) {
        var value = searchBox.value;
        var hiddenClass = targetClass + "SearchHidden";

        //Nothing in the box, remove <targetclass>searchhidden class
        if (value.length < 1) {
            $("." + hiddenClass).removeClass(hiddenClass);
            return;
        }
        var targets = $("." + targetClass);

        console.log(targets);

        for (var i = 0; i < targets.length; i++) {
            var currentTarget = $(targets[i]);

            var parent = currentTarget.closest(".row");

            if (!currentTarget.text().trimLeft().startsWith(value)) {
                $(parent).addClass(hiddenClass);
            } else {
                $(parent).removeClass(hiddenClass);
            }
        }
    };
})();

Consider changing starts with to a match?
