jQuery最佳实践(不断更新中...)

<script type="text/javascript" src="http://xxx.com/jquery.min.js "></script>
<script type="text/javascript">
if(typeof jQuery == ‘undefined‘){
    document.write("<script type=‘text/javascript‘ src=‘js/jquery.min.js‘></script>");
}
</script>

    $(document).on(‘click‘,‘#qiehuan‘,function(){
        var isFs = $(this).attr("datas");
        $.cookie("isFs",isFs,{ expires: 7 }); 
    });
