optiontransferselect标签

optiontransferselect标签左右各有一个列表，右边的选项可以转到左边，左边的选项也可以转到右边。optiontransferselect标签是利用两个<select>实现的。代码如下：

 1 <struts:head theme="ajax" />    <!-- 使用Ajax主题 -->
 2 
 3 <style type="text/css">
 4 body,td {
 5     font-size: 12px;
 6 }
 7 select {
 8     width: 120px; 
 9 }
10 </style>
11 </head>
12 
13 <body>
14 <%
15     List<String> provinceSelected = new ArrayList<String>();  // 选中省份的List
16 
17     provinceSelected.add("北京");                              // 添加数据
18     provinceSelected.add("上海");
19     provinceSelected.add("天津");
20     provinceSelected.add("重庆");
21     provinceSelected.add("河北");
22     provinceSelected.add("河南");
23     provinceSelected.add("山东");
24     provinceSelected.add("山西");
25     provinceSelected.add("江苏");
26     provinceSelected.add("浙江");
27 
28     request.setAttribute("provinceSelected", provinceSelected);  // 放到request中
29 
30     List<String> provinceUnselected = new ArrayList<String>();   // 没有选中省份的List
31 
32     provinceUnselected.add("湖南");                               // 添加数据
33     provinceUnselected.add("湖北");
34     provinceUnselected.add("云南");
35     provinceUnselected.add("广东");
36     provinceUnselected.add("广西");
37 
38     request.setAttribute("provinceUnselected", provinceUnselected);  // 放到request中
39 %>
40 <struts:form action="login">
41     <struts:optiontransferselect name="province"
42         doubleList="#request.provinceSelected"
43         list="#request.provinceUnselected" doubleName="city" leftUpLabel="向上"
44         leftDownLabel="向下" rightDownLabel="向下" rightUpLabel="向上"
45         leftTitle="已经选中的省份" headerKey="" headerValue="---请选择省份---"
46         rightTitle="剩余的省份" />
47 </struts:form>
48 
49 </body>
