本文主要为大家介绍了双向select控件Bootstrap Dual Listbox的使用方法，Bootstrap Dual列表是一个为响应Twitter优化的列表框插件，它可以用在所有的现代浏览器和触摸设备上，分享给大家，具体如下：

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="//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：
