JS高手请进！！！关于body的onload()问题，高分求解！！！
在做文本编辑的时候，就是那种能编辑文本的东东！！在哪个页面中含有一个<iframe name="Composition" width="80%" marginwidth="5" height="500" marginheight="1" scrolling="auto" class="Composition" id="Composition"> </iframe>，编辑文本用的。
当我要修改一条于有的信息的时候，希望在页面加载的时候就显示信息的内容，我是如下做的：
<script language="JavaScript">
function bcwrite()
{
var content ='<%=wpContent%>';//查询出来的信息的内容
Composition.document.body.innerHTML=content;
}
</script>
在页面加载的时候：
<body onLoad=" MM_callJS('bcwrite()')">调用这个JS函数；这是会报错：
Composition.document.body为空或者不是对象！
如果不是在onLoad的时候调用的话，不会抛出错误，但是那样需要按钮触发，不好。
不知大家在做文本编辑的时候是如何做的，在什么时候加载信息的内容。请指教！！！

不好意思，刚才没理解你的意思，
你用按纽时真的调用了这个Composition.document.body.innerHTML=content;
，而且正确？我怀疑你没有调用这一句。
<script language="JavaScript">
function bcwrite()
{
var content ='<%=wpContent%>';//查询出来的信息的内容
Composition.document.body.innerHTML=content;
}
</script>
这个要放在页面的开始部分。

是的，以上的方法都用过了！如此调用的话<body onLoad="bcwrite()">，会报错Composition.document.body为空或者不是对象！Top

to:liutang2(Believe I Can Fly！) 我如下写：
<script language="JavaScript">
function bcwrite()
{
Composition.document.body.innerHTML='<%=wpContent%>';
}
</script>
无论是放在<body>之前还是之后都是一样的错误！Top

试试这个
<SCRIPT LANGUAGE="JavaScript">
<!--
Composition.onload=new function() {
bcwrite();
}
//-->
</SCRIPT>Top

<body id="body" onLoad="bcwrite()">
把
Composition.document.body.innerHTML=content;
改成
document.body.innerHTML=content;
把你的代码贴全点，说得清楚以一点！Top

name="Composition" width="80%" marginwidth="5" height="500" marginheight="1" scrolling="auto" class="Composition" id="Composition"> </iframe>
你在这句话的后面，把正面的javascript加到里面
<script language="JavaScript">
var content ='<%=wpContent%>';//查询出来的信息的内容
Composition.document.body.innerHTML=content;
</script>

或者将
<script language="JavaScript">
function bcwrite()
{
var content ='<%=wpContent%>';//查询出来的信息的内容
Composition.document.body.innerHTML=content;
}
</script>
改成这样
<script language="JavaScript">
function bcwrite()
{
var content ='<%=wpContent%>';//查询出来的信息的内容
document.all.Composition.document.body.innerHTML=content;
}
</script>
