关于select的多选框实现

借助easyui-combobox来实现, 具体代码如下

<td>多选</td>
                    <td>
                        <select id="businessContent" style="height: 30px" name="businessContent" multiple="multiple"
                                 class="easyui-combobox" data-options="multiple:true">
                            <option value="">--请选择--</option>
                            <option value="1">A</option>
                            <option value="2">B</option>
                            <option value="3">C</option>
                        </select>
                    </td>

设置回显值, 通过其 setValues. 传一个数组即可.注意在页面加载完后进行

var businessContentVal = '${review.businessContent}';
        if (businessContentVal != null && businessContentVal != '') {
            var arr = businessContentVal.split(",");
            $("#businessContent").combobox("setValues",arr);
        }
