js实现H5网页飘窗寻技术

1.<div style="z-index: 1000; position: absolute; filter: Alpha(opacity = 90); width: 100px;padding: 10px; border: 1px solid #333" id="img" align="center">
<a href="javascript:void(0);" id="popInfo" style="text-decoration: none;color:#333">关于xxx的通知</a>
</div>

js代码

$('#popInfo').click(function() {
layer.open({
title : '通知',
type : 1,
area : [ '560px', '420px' ],
content : content
});
})
