我的任务
分享求救，请各位高手帮忙。
可以帮我看看代码，页面执行下面的函数：
<script language="javascript">
function Extra()
{
var sHTML="<body bgColor='#000000'"+">"
var sScript = "<script language=Jscript.Encode src='/effect/gun.js'>" + "</" + "script>";
parent.message.document.body.insertAdjacentHTML("afterBegin",sHTML+sScript);
}
这里的message是一个iframe代码如下：
<script language="javascript">
document.write ('<iframe src="textbox.jsp?id=<%=request.getParameter("id")%>&action=<%=request.getParameter("action")%>" id="message" width="650" height="500" bgcolor = "#000000" align=center></iframe>')
frames.message.document.designMode = "On";
</script>
当我执行Extra()时把代码插到message(iframe)里面的textbox.jsp页面里var sScript = "<script language=Jscript.Encode src='/effect/gun.js'>" + "</" + "script>";可以实现，但是var sHTML="<body bgColor='#000000'"+">"就实现不了，这是为什么呢，请指点指点。var sHTML="<body bgColor='#000000'"+">"这个语句该怎么实现呢？

直接用js控制bgColor吧，
function Extra()
{ var sScript = "<script language=Jscript.Encode src='/effect/gun.js'>" + "</" + "script>";
parent.message.document.body.insertAdjacentHTML("afterBegin",sScript);
parent.message.document.body.bgColor="#000000";
}
function Extra()
{ var sScript = "<script language=Jscript.Encode src='/effect/gun.js'>" + "</" + "script>";
parent.message.document.body.insertAdjacentHTML("afterBegin",sScript);
parent.message.document.body.bgColor="#000000";
}
