solved Jquery or ?

$( document ).ready(function() {
    // something in here, this happens after the page loads.
});

function jrLoad(id,url,round_id,round_num) {
    if (typeof url == "undefined") {
        return false;
    }
    if (url == 'blank') {
        $(id).hide();
    }
    else if (id == '#hidden') {
        $(id).hide();
        $(id).load(url);
    }
    else {
        if (id == '#rank') {
            var t = $('#rank').height();
            if (t == null) {
                $('#main').html('<div class="inner"><div id="rank"></div></div>');
            }
        }
        var h = $(id).height();
        if (h > 150) {
            $(id).height(h);
        }

            $(id).load(url,function() {
                var l = $(id).text();
                if (l.length < 1 && id != '#player') {
                    $(id).html('');
                }
                if (h > 150) {
                    $(id).height('100%');
                }
                if (round_id && round_num > 0) {
