bootstrap 之下拉多选

效果如图：

一、HTML代码

 <label class="col-sm-1 control-label text-right" for="ds_host">
                科室:</label>
            <div class="col-sm-3">
                <select id="sl_ks" class="selectpicker" data-live-search="false" multiple="multiple">
                    <option value="0" selected="selected">全部</option>
                </select>
            </div>

二、js绑定值

        $.ajax({
                type: 'get',
                url: 'jgdx.ashx?action=bindBm',
                dataType: 'json',
                success: function (datas) {//返回list数据并循环获取  
                    var select = $("#sl_ks");
                    for (var i = 0; i < datas.length; i++) {
                        select.append("<option value='" + datas[i].id + "'>"
                                 + datas[i].gzbm + "</option>");
                    }
                    $('#sl_ks.selectpicker').selectpicker('val', '');
                    $('#sl_ks.selectpicker').selectpicker('refresh');
                }
            });

三、后台构造的json格式

[{"gzbm":"办公室","id":"1"},
{"gzbm":"领导班子","id":"2"},
{"gzbm":"研发部","id":"3"},
{"gzbm":"后勤部","id":"4"},
{"gzbm":"质检部","id":"5"},
{"gzbm":"媒介部","id":"19"}]
