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="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="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> <select multiple="multiple" size="10" name="duallistbox_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> <select multiple="multiple" size="10" name="duallistbox_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#" %> 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; } } }
