一看就是不是搞前端的,只是简单的CSS透明。
<button type="button" onclick="fun()">弹出窗口</button>
<div id="mode"></div>
<div id="div">
<iframe src="http://www.baidu.com" scrolling="no" frameborder="0" width="100%" height="100%"></iframe>
</div>
<script type="text/javascript">
function fun(){
document.getElementById("mode").style.display="block";
document.getElementById("div").style.display="block";
}
</script>
</body>
</html>
