javascript 装载iframe子页面，自适应高度

复制代码 代码如下:

<div id="frameBox">
<iframe id="frameWin" src="1.html" name="opWin" style="width:100%; height:100% " frameborder="0" scrolling="no"></iframe>
</div>

复制代码 代码如下:

function aa(){
var newHeight = document.body.scrollHeight + 20 + "px";
window.parent.document.getElementById("frameBox").style.height = newHeight;
//以上firefox通过，但是ie6必须加上下面这句，不然iframe高度是改了，但是可见区域没有改
window.parent.document.getElementById("frameWin").style.height = newHeight;
}

复制代码 代码如下:

<div style="border:1px solid #7e99c6" id="frameBox">
<iframe id="frameWin" src="01.html" name="opWin" style="width:100%; height:100% " frameborder="0" scrolling="no" onload="test2()"></iframe>
</div>

复制代码 代码如下:

function test2(){
var frameWin = document.getElementById("frameWin");
var frameBox = document.getElementById("frameBox");
var newHeight;
if (frameWin.Document){
newHeight = frameWin.Document.body.scrollHeight + 20 + "px";
}else{
newHeight = frameWin.contentDocument.body.scrollHeight+ 20 + "px";
}
frameWin.style.height = newHeight;
frameBox.style.height = newHeight;
}
