通过嵌套iframe 可以获取另一个页面的东西
<script type="text/javascript">
$(function () {
document.getElementById("ifm").src ="";//Url地址
$("#ifm").load(function () {
var h = document.body.clientHeight;
var w = document.body.clientWidth;
document.getElementById("ifm").height = h + "px";
document.getElementById("ifm").width = w + "px";
});
})
</script>
<body style="overflow-y:hidden;overflow-x:hidden">
<div id="pageone" style="">
<iframe name="ifm" id="ifm" scrolling="yes" style="background-color: transparent;" marginwidth="0" marginheight="0" frameborder="0">
