EasyUI combobox下拉多选框的实现

combobox实现下拉列表多选， 效果如下

一、先定义一个easyui-combobox

<td>
     目标人群:
</td>
<td>
     <input id="cmbAgeType" class="easyui-combobox" name="dept" />
</td>

二、在javascript中写入如下代码

   $(\'#cmbAgeType\').combobox({
                url: \'AjaxHandler/RadioCommon.ashx?action=bindAgeType\',//对应的ashx页面的数据源
                method: \'get\',
                valueField: \'CID\',//绑定字段ID
                textField: \'CNAME\',绑定字段Name
                panelHeight: \'auto\',//自适应
                multiple: true,
                formatter: function (row) {
                    var opts = $(this).combobox(\'options\');
                    return \'<input type="checkbox" class="combobox-checkbox" id="\' + row[opts.valueField] + \'">\' + row[opts.textField]
                },

                onShowPanel: function () {
                    var opts = $(this).combobox(\'options\');
                    var target = this;
                    var values = $(target).combobox(\'getValues\');
                    $.map(values, function (value) {
                        var el = opts.finder.getEl(target, value);
                        el.find(\'input.combobox-checkbox\')._propAttr(\'checked\', true);
                    })
                },
                onLoadSuccess: function () {
                    var opts = $(this).combobox(\'options\');
                    var target = this;
                    var values = $(target).combobox(\'getValues\');
                    $.map(values, function (value) {
                        var el = opts.finder.getEl(target, value);
                        el.find(\'input.combobox-checkbox\')._propAttr(\'checked\', true);
                    })
                },
                onSelect: function (row) {
                    var opts = $(this).combobox(\'options\');
                    var el = opts.finder.getEl(this, row[opts.valueField]);
                    el.find(\'input.combobox-checkbox\')._propAttr(\'checked\', true);
                },
                onUnselect: function (row) {
                    var opts = $(this).combobox(\'options\');
                    var el = opts.finder.getEl(this, row[opts.valueField]);
                    el.find(\'input.combobox-checkbox\')._propAttr(\'checked\', false);
                }
            });

三、后台传到前台的Json格式
