按照上面的写应该可以了吧,用到的DHTML+JS,慢慢来,多试就可以了.
加上这句即可删除document.getElementById("sel1").options[i].removeNode(true);
下面这个直接点击就可以传送到另一个Select，采用DOM，能适合在不同的浏览器，希望您能参考一下，至于按钮点击传送您可以自己尝试在这个基础上修改：<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>两个select之间传值.html</title>
<script type="text/javascript">
function Transfer(Num,argsValue,argsText){
var sel1 = document.getElementById("s1");
sel1.remove(Num);
var sel2 = document.getElementById("s2");
var oOption = document.createElement("option");
sel2.options.add(oOption,parseInt(argsValue));
oOption.text = argsText;
oOption.selected = false;
}
</script>
</head>
<body>
<select id="s1" multiple="multiple" onchange="Transfer(this.selectedIndex,this.value,this.options[selectedIndex].text)" style="width:100px;height:100px">

很早写的，只适用于iemoveList<table>

很早以前写的一个例子：<script language="JavaScript">

</script>
<html>
<body>
<table align="center">

<td>
<select name="mae" size="20" style="width:120" MULTIPLE>
