    <script src="Easyui/locale/easyui-lang-zh_CN.js"></script>
    <script type="text/javascript">
        $(function () {
            $('#cc').combobox({
                url: 'Home/getOffice',
                valueField: 'id',
                textField: 'text',
                required: true,
                queryParams: { OFFID: 100 },
                editable: false,//不可编辑，只能选择
                disabled: false,
                value: '选择部门'
            });
        });
        function getValue()
        {
            var value = $('#cc').combobox('getValue');
            alert(value);
        }
        function getText()
        {
            var text = $('#cc').combobox('getText');
            alert(text);
        }
    </script>
</head>
<body>
  <input id="cc" name="dept" value=""    />       
  <div><input type="button" value="获取Value的值" style="width:100px;" onclick="getValue()"/>&nbsp;&nbsp;&nbsp;<input type="button" value="获取text的值" onclick="getText()" style="width:100px;" /></div>  
<div style="height:30px;"></div>
<span>combobox 另一种定义形式</span>
<div>
<select id="Select1" class="easyui-combobox" name="dept" style="width:200px;">
    <option value="aa">aitem1</option>
    <option>bitem2</option>
    <option>bitem3</option>
    <option>ditem4</option>
    <option>eitem5</option>
</select>
</div>
</body>
</html>


3、Home后台代码

        public JsonResult getOffice(string OFFID)
        {
             Int32 officeID = Convert.ToInt32(OFFID);
            List<ComboModel> myList = new List<ComboModel>();          
        
                for (int i = 1; i < 20; i++)
                {
                    ComboModel model = new ComboModel()
                    {
                      id=i,
                       text="部门"+i.ToString()
                    };
                    myList.Add(model);
                }

            
            return Json(myList, JsonRequestBehavior.DenyGet);
        }
   public class ComboModel
    {
        public System.Int32 id { get; set; }
        public System.String text { get; set; }
    }
