    window.parent.$(function () {//使用window.parent调用父级jquery
        var head = document.getElementsByTagName("head").item(0);
 
        var linkList = window.parent.document.getElementsByTagName("link");//获取父窗口link标签对象列表
        for (var i = 0; i < linkList.length; i++) {
            var _link = document.createElement("link");
            _link.rel = 'stylesheet'
            _link.type = 'text/css';
            _link.href = linkList[i].href;
            head.appendChild(_link);
        }
 
        var scriptList = window.parent.document.getElementsByTagName("script");//获取父窗口script标签对象列表
        for (var i = 0; i < scriptList.length; i++) {
            var _script = document.createElement("script");
            _script.type = 'text/javascript';
            _script.src = scriptList[i].src;
            head.appendChild(_script);
        }
