iframe自适应高度

Question

<iframe id="myframe" name="myframe" width="566px" frameBorder="0" src="" runat="server"></iframe>
iframe 加上runat="server"了,因为我在后台要改变myframe的src,找了很多自适应高度的js但是不能用啊,一般都Onload=jvascript：SetHeight(this)， 关键是加了ruant="server" 不能用onload事件了,请教下还有什么办法能使iframe自适应高度？

Answer 1

你可以在body里面写onload
把iframe的ID传进去

Answer 2

写了,试了很多方法都不行,只有onload="javascript:SetWinHeight(this)", 把this传过去的时候可以

Answer 3

<iframe id="myframe" name="myframe" width="566px" frameBorder="0" src="default.aspx" onload="Javascript:SetWinHeight(this)"></iframe>function SetWinHeight(obj)
{
var win=obj;
if (document.getElementById)
{
if (win && !window.opera)
{
if (win.contentDocument && win.contentDocument.body.offsetHeight) win.height = win.contentDocument.body.offsetHeight; 
else if(win.Document && win.Document.body.scrollHeight)
win.height = win.Document.body.scrollHeight+100;
}
}
}
就这样的时候可以,然后我改了不用onload,把js代码放到iframe下面去也不行...试了半天了就不行..

我试过了,也不行啊,src="javascript:getSrc()"这样的话页面就一直刷新,关都关不了,我也不清楚为什么这样,不信你一会远程看看...
