效果图：

一、使用

1、引用css和js文件

 <link href="scripts/bootstrap-3.3.5-dist/css/bootstrap.min.css" rel="stylesheet" />
 <!--<link href="//cdnjs.cloudflare.com/ajax/libs/prettify/r298/prettify.min.css" rel="stylesheet">-->
 <link href="scripts/duallistbox/bootstrap-duallistbox.min.css" rel="stylesheet" />
 <script src="scripts/jquery/jquery-2.1.4.min.js"></script>
 <script src="scripts/bootstrap-3.3.5-dist/js/bootstrap.min.js"></script>
 <!--<script src="https://cdnjs.cloudflare.com/ajax/libs/prettify/r298/run_prettify.min.js"></script>-->
 <script src="scripts/duallistbox/jquery.bootstrap-duallistbox.min.js"></script>

2、初始化class属性为demo1的select元素

<script type="text/javascript">
  $(function () {
   var demo2 = $('.demo1').bootstrapDualListbox({
    nonSelectedListLabel: 'Non-selected',
    selectedListLabel: 'Selected',
    preserveSelectionOnMove: 'moved',
    moveOnSelect: false,
    nonSelectedFilter: 'ion ([7-9]|[1][0-2])'
   });

   $("#showValue").click(function () {
    alert($('[name="duallistbox_demo1"]').val());
   });
  });
 </script>

3、html代码

<div class="col-md-7">
  <select multiple="multiple" size="10" name="duallistbox_demo1" class="demo1">
   <option value="1">Option 1</option>
   <option value="2">Option 2</option>
   <option value="3" selected="selected">Option 3</option>
   <option value="4">Option 4</option>
   <option value="5">Option 5</option>
   <option value="6" selected="selected">Option 6</option>
   <option value="7">Option 7</option>
   <option value="8">Option 8</option>
   <option value="9">Option 9</option>
   <option value="10">Option 10</option>
  </select>
  <br />
  <input id="showValue" type="button" value="show selected data" />
 </div>

这样就完成了插件的调用

二、扩展

一个通用的、初始化数据的js函数：

/*初始化duallistbox*/
  //queryParam1：参数
  //selectClass：select元素class属性
  //selectedDataStr：选中数据，多个以,隔开
  function initListBox(queryParam1,selectClass, selectedDataStr) {
   var paramData = {
    'testParam1': queryParam1
   }
   $.ajax({
    url: 'DataHandler.ashx',
    type: 'get',
    data: paramData,
    async: true,
    success: function (returnData) {
     var objs = $.parseJSON(returnData);
     $(objs).each(function () {
      var o = document.createElement("option");
      o.value = this['id'];
      o.text = this['name'];
      if ("undefined" != typeof (selectedDataStr) && selectedDataStr != "") {
       var selectedDataArray = selectedDataStr.split(',');
       $.each(selectedDataArray, function (i, val) {
        if (o.value == val) {
         o.selected = 'selected';
         return false;
        }
       });
      }
      $("." + selectClass + "")[0].options.add(o);
     });
     //渲染dualListbox
     $('.' + selectClass + '').bootstrapDualListbox({
      nonSelectedListLabel: 'Non-selected',
      selectedListLabel: 'Selected',
      preserveSelectionOnMove: 'moved',
      moveOnSelect: false//,
      //nonSelectedFilter: 'ion ([7-9]|[1][0-2])'
     });
    },
    error: function (e) {
     alert(e.msg);
    }
   });
  }

html代码：

<div class="col-md-7">
  <select multiple="multiple" size="10" name="duallistbox_demo2" class="demo2">
  </select>
  <br />
  <input id="showValue" type="button" value="show selected data" />
 </div>

调用：

$(function () {
   //初始化
   initListBox('hangwei.cnblogs.com', 'demo2');

   $("#showValue").click(function () {
    alert($('[name="duallistbox_demo2"]').val());
   });
  });

DataHandler.ashx代码：

<%@ WebHandler Language="C#" Class="DataHandler" %>

using System;
using System.Web;
using System.Collections.Generic;
using Newtonsoft.Json;

public class DataHandler : IHttpHandler {
 
 public void ProcessRequest (HttpContext context) {
  var china = new { id = "China", name = "中国" };
  var usa = new { id = "USA", name = "美国" };
  var rsa = new { id = "Russia", name = "俄罗斯" };
  var en = new { id = "English", name = "英国" };
  var fra = new { id = "France", name = "法国" };
  List<object> list = new List<object>();
  list.Add(china);
  list.Add(usa);
  list.Add(rsa);
  list.Add(en);
  list.Add(fra);
  string returnJson = JsonConvert.SerializeObject(list);
  context.Response.ContentType = "text/plain";
  context.Response.Write(returnJson);  
 }
 
 public bool IsReusable {
  get {
   return false;
  }
 }

}

效果：

本文的demo使用的开发环境：VS2013、.NET Framework4.5.
