从后台返回一条JSON数据，如何转换成ext的record

Question

var r = action.result.jsondata;
想把json转换成record，然后EditUserInfofp.getForm().loadRecord（record）进行页面加载

Answer 1

json格式是什么
record格式是什么 
说明下

Answer 2

 // 定义一个用户对象,这样便于我们动态的添加记录,虽然也可以设置成匿名内置对象
    var User = Ext.data.Record.create([
           // 下面的 "name" 匹配读到的标签名称, 除了 "birthDay",它被映射到标签 "birth"
           {name: 'id', type: 'int' },
           {name: 'name', type: 'string'},
   {name: 'area'},
           {name: 'email', type: 'string'},
           {name: 'age', type: 'int'},             // automatic date conversions
           {name: 'birth', type: 'date'},
           {name: 'sex', type: 'bool'}
      ]);var p = {
             name: '新用户' + n,
                    area: '北京',
email: '[email protected]',
                    age: 20,
                    birth: (new Date()).clearTime(),
                    sex: 1
             };var pp = new User(p);EditUserInfofp.getForm().loadRecord（pp）

//主页面定义一个store
var fields = ["user_no","user_id","user_name","lpwd","shop_no","shop_name","isadmin","lltime","available"];
var USERstore = new Ext.data.GroupingStore({
        proxy:new Ext.data.HttpProxy(
        {
            url:"SysUserBrowse.aspx?param=SysUser"
        }),
        reader:new Ext.data.JsonReader(
        {
            fields:fields,
            root:"data",
            id:"user_no",
            totalProperty:"totalCount"
        }),
        sortInfo:{field:'user_no',direction: "ASC"}
});
//加载时参数
USERstore.load({params:{start:0,limit:pageSize}});//定义一个EditUserInfoWin，在添加数据提交成功后，想加载刚才的最新记录
EditUserInfofp.form.submit({
                                    url:"SysUserHandle.aspx?func_id="+func_id+"&&user_no="+EditUserInfofp.form.findField("user_no").getValue(),
                                    params:{dp_datas:jsonData},
                                    method:"POST",
                                    success:function(form,action)
                                    {
                                        var flag=action.result.success;
                                        if(flag=="true")
                                        {
                                            Ext.MessageBox.show({
                                                title: '提示',
                                                msg:'信息保存成功!',
                                                animEl:'saveid',
                                                buttons:Ext.Msg.OK,
                                                closable:false,
                                                icon:Ext.MessageBox.WARNING,
                                                fn:function(btn)
                                                {
                                                    if(btn=="ok")
                                                    {
                                                        USERstore.reload();
var r = action.result.jsondata;//此处USERstore是reload了，但是在此处访问时访问不到最新的数据，所以只能在这边做处理，返回刚才的最新数据r，并想转换成record，form重新加载                                                                                                            }
                                                }
                                            });
                                        }
                                        else
                                        {
                                            var message=action.result.error
                                            Ext.MessageBox.show({
                                                title: '提示',
                                                msg:message,
                                                animEl:'saveid',
                                                icon:Ext.MessageBox.ERROR
                                            });
                                        }
                                    },
                                    failure:function(form,action)
                                    {
                                        Ext.MessageBox.show({
                                            title:'提示',
                                            msg:'保存信息失败!',
                                            animEl:'saveid',
                                            icon:Ext.MessageBox.ERROR
                                        });
                                    }
                                });

Answer 4

你的思路应该对我来说是很有用的，但是感觉有点繁琐，毕竟当字段比较多的时候，那么Ext.data.Record.create的时候就比较繁琐了，我刚才把我的代码贴在上面了，不晓得大家还能看的懂，其实意思就是：无路是修改还是添加数据后，模态Window不关闭，直接重新加载刚才保存的数据

Answer 5

试试：if(btn=="ok")
                                                    {
                                                        USERstore.reload();
var r = action.result.jsondata;USERstore.loadData(r);
//此处USERstore是reload了，但是在此处访问时访问不到最新的数据，所以只能在这边做处理，返回刚才的最新数据r，并想转换成record，form重新加载                                                                                                            }
                                                }

Answer 6

我这边loadData不行，是不是对r的格式有要求？？？
USERstore的格式已经定义在前面了，那么返回的r应该格式是什么样的？
