之前不是回過你了？iframe和父頁是不同的區域，點擊iframe是無法響應父頁的click事件的，用透明的層遮蓋住iframe（跨域）或者沒有跨域的情況下給iframe添加click事件隱藏div
$("#contentFrame").load(function () {
var mainheight = $(this).contents().find("body").height();
$(this).height(mainheight);
//////////////////////////////增加下面的代碼觸發父頁綁定的click事件
$(this).contents().click(function () {
$(parent.document).trigger('click');
});
//////////////////////////////
});
或者透明層遮蓋住iframe
<div id="divmain" style="position:relative">
<div style="position:absolute;left:0px;top:0px;width:100%;height:100%;background:#000;filter:alpha(opacity=0);opacity:0"></div>
<iframe name="contentFrame" id="contentFrame" width="100%" height="500" allowtransparency="true" scrolling="no" border="0" frameborder="0" src="http://www.baidu.com" ></iframe>
</div>
