.document引用到是的 iframe所在页面对象，
.Document (大写D)，才能引用到iframe内含对象

<html>
<head>
<script>
function SetCwinHeight(obj)
{
// alert(obj.document.getElementById("tDiv").innerText);//可以获得当前页面id为tDiv的div的值
 alert(obj.Document.all.tDiv.innerText);
//这个可以获得text.html里面id为tDiv的div的值、、、
}
</script>
</head>
<body>
<iframe src="test.html" onload="SetCwinHeight(this);" width="600px' id="myframe" 
name="myframe">
</iframe>
<div id="tDiv">
tdiv
</div>
</body>
</html

>
test.html


...
<div id="tDiv" name="tDiv">sdiv</div>
...

下面是兼容ie，ff。chome等的写法

、
function SetCwinHeight()
{
  var obj=document.getElementsByTagName("iframe")[0];
 // var obj2=document.getElementById("myframe");//chome和firefox不支持id取iframe
  //alert(obj2);
  var str="";
  var cwin=obj;
  var sobj=null;
  if (document.getElementById){
    if (cwin && !window.opera){
      if (cwin.contentDocument){
       sobj = cwin.contentDocument; //FF NS
       alert("ff or chome");
       }
      else if(cwin.Document){
        sobj = cwin.Document;//IE
        alert("ie");
        }
     }
     else{ 
        if(cwin.contentWindow.document){
        sobj = cwin.contentWindow.document;//Opera
	    alert("opera ");
        }

     }
   }
    for(i in sobj){
     str+=i+"<br/>";
    } 
    document.write(str);

}
