div放在最外层

<div id="loadingImg" style="height: 100%;width: 100%;background-image: url('img/uploading.gif');background-position: center; position: fixed;top: 1px;background-repeat: no-repeat;background-color:#FFFFFF;filter:alpha(opacity=80); -moz-opacity:0.80; opacity:0.80;display: none;z-index: 9999 "></div>

         if (r) {
             parent.window.$("#loadingImg").css("display","");//显示上边的div效果
             $.ajax({
