利用两个select标签,当双击一个标签的选项后,该选项会添加到另一个选项中,并且当前选项移除,效果下图:



 

代码如下:

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>

<body>
<select multiple="multiple" id="s1" style="width: 200px;height: 200px" ondblclick="move(this,getElementById('s2'))">
<option value="a">李逍遥</option>
<option value="b">赵灵儿</option>
<option value="c">林月如</option>
<option value="d">刘晋元</option>
<option value="e">唐钰小宝</option>
<option value="f">阿奴</option>
</select>
<select multiple=" multiple" id="s2" style="width: 200px;height: 200px" ondblclick="move(this,getElementById('s1')>
</select>
</body>
<script type="text/javascript">
function move(s1,s2){
var ops1=s1.options;
var ops2=s2.options;
var index=s1.selectedIndex;
if(index<0){
return;
}
var op=new Option();
op.value=ops1[index].value;
op.text=ops1[index].text;

ops2.add(op);
ops1.remove(index);
}
</script>
</html>
