<body bgcolor="#FFFFFF" text="#000000">
<select name="li">
  <option value="1">aaa</option>
  <option value="2">bbb</option>
  <option value="3">ccc</option>
</select>
<input type="submit" name="Submit" value="Submit" onclick="aa()">
<table width="100%" border="1">
<script language="javascript">
function aa()
{document.write("<TR><TD>hg</TD></TR>")
}
</script>
</table>
</body>
结果是将原有控件替换，我不想替换原有控件如何解决？

</SCRIPT>
下面的方法也可以，方法很多：
<div id=DivID></div>
<input type=button onclick="test()" value="addd">
<script>
function test(){
var sHTML="<table border='2'><tr><td>test</td><tr></table>"
document.all.DivID.insertAdjacentHTML("afterBegin",sHTML );
}
</script>
