使用easyui时 进入一个新页面 前要经过一个页面混乱的时候 才到正常的页面去

var width = $(window).width();
        var height = $(window).height();
        var html = "<div id='loading' style='position:absolute;left:0;width:100%;height:" + height + "px;top:0;background:#EFEFEF;opacity:1;filter:alpha(opacity=100);'>";
        html += "<div style='position:absolute;cursor1:wait;left:" + ((width / 2) - 75) + "px;top:200px;width:150px;height:16px;padding:12px 5px 10px 30px;";
        html += "background:#EFEFEF url(/yxt-admin/js/easyui/themes/gray/images/loading.gif) no-repeat scroll 5px 10px;border:2px solid #ccc;color:#000;'>";
        html += "正在加载，请等待...";
        html += "</div>";
        html += "</div>";
        window.onload = function () {
            var mask = document.getElementById('loading');
            mask.parentNode.removeChild(mask);
        };
        document.write(html);        

加上这段代码就好了！
