[Java教程]Jquery双向select控件Bootstrap Dual Listbox


效果预览:

一. 下载插件

github地址:https://github.com/istvan-ujjmeszaros/bootstrap-duallistbox

也可以在这个网站中下载:http://www.virtuosoft.eu/code/bootstrap-duallistbox/(排版很好,推荐做为API参考地址)

二. 使用

引用css和js文件:

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

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>

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。

三. 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;    }  }}

四. 总结

1. 关于jquery版本问题,我自己写的demo使用的是1.10.2,实际上,只要jquery版本大于1.9.1即可,主要是匹配Bootstrap3.3.5版本需求的最低jquery版本。

   另外,如果忽略Bootstrap报错,1.8.2版本也是可行的,控件渲染没有问题。

2. 本文demo使用的开发环境: VS2013 ,.NET Framework4.5
