给Easyui combobox设定默认值

      今天做到那个北理工二期的项目,里面刚好有几个dialog需要弄一个默认值,一般是选择启用与否,但是,为了方便用户,最好有一个默认值,所以,增加一个默认值的属性.代码入下:

JS代码:

 

$(function () {

            $('#OfficeInfoList').datagrid({

                toolbar: [{

                    text: '新D?增?',

                    iconCls: 'icon-add',

                    handler: function () {

                        $('#dlg').dialog('open').dialog('setTitle', '新D?增?办°ì公1?室êò信D?息￠');

                        $('#dlg_form').form('clear')

                        $('#buildname').combobox('reload', '/Iframes/ClassRoomInfo.aspx?from=sel-Buildname');

                        $('#departmentname').combobox('reload', '/Iframes/ClassRoomInfo.aspx?from=sel-DepartName');

                        $('#kt_dk').combobox('reload', '/Iframes/ClassRoomInfo.aspx?from=sel-kt_dk');

                        $('#dg_dk').combobox('reload', '/Iframes/ClassRoomInfo.aspx?from=sel-dg_dk');

                        $('#zbdnjd').combobox('reload', '/Iframes/ClassRoomInfo.aspx?from=sel-zbdnjd');

                        $('#kt_gzfs').combobox('setValue', '1');//这个就是需要给默认值的地方,1表示启用,与下面的值对应.

                        $('#kt_sfqy').combobox('select', '1');//经过测试,select也可以的

                        url = '/Iframes/OfficeInfo.aspx?from=sel-add';

                    }

                },

                ......

html代码:

 

< div   class ="fitem">
                 < label >
                    工作方: </ label >
                 < select   id ="kt_gzfs"   class ="easyui-combobox"   name ="kt_gzfs"   data-options ="panelHeight:'auto'"   style =" padding : 2px;
                     width : 141px;">
                     < option   value ="1" selected ="selected"> 自动</ option >
                     < option   value ="0"> 手动 </ option >
                 </ select >
             </ div >

第二种情况就是:如果是动态获取的数据的话,上面的方法是不可以的,在网上找到另一种方法,代码如下:

前台:

        $(document).ready(function () {

            

            $('#BuildingId').combobox('reload', 'TheLatestMeterInfo.aspx?from=sel-Buildname');

            $.ajax({

                type: "POST",

                url: location.href,

                success: function () {

                    var data = $('#BuildingId').combobox('getData');

                    if (data.length > 0) {

                        $('#BuildingId').combobox('select', data[0].ID);

                        var BuildingName = $("#BuildingId").combobox('getValue');

                        $('#List').datagrid('reload', {

                            from: 'sel',

                            BuildingName: BuildingName

                        })

                    }

                }

            });

        });

 

后台:

//加载建筑物信息

            if (!string.IsNullOrWhiteSpace(Request["from"]) & Request["from"] == "sel-Buildname")

            {

                List<BuildingInfoForModel> mList = DataLoader.GetBuildingInfo();

                var queryDdlData = from m in mList

                                   select new { ID = m.BuildID, Name = m.BuildName };

                Response.Write(JsonHelper.Serialize(queryDdlData));

                Response.End();

            }
