if(self!=top){top.location=self.location;}
function switchSysBar(){
if (switchPoint.innerText==3){
switchPoint.innerText=4
document.all( "frmTitle ").style.display= "none "
}else{
switchPoint.innerText=3
document.all( "frmTitle ").style.display= " "
}}
</script>

<table border= "0 " cellPadding= "0 " cellSpacing= "0 " height= "100% " width= "100% ">
<tr>
<td align= "middle " noWrap vAlign= "center " id= "frmTitle ">
<iframe frameBorder= "0 " id= "carnoc " name= "carnoc " scrolling=no src= "LeftTree.aspx " style= "HEIGHT: 100%; WIDTH: 170px; Z-INDEX: 2 ">
</iframe>

要簡單實現的話， lz用dw，里面有可以新建立框架，有好幾個模式給你選。 你建立了。然后拷貝到vs中就可以了。

框架。。或者你内嵌iframe、DIV 等对象都可以达到这个效果。
