extjs4.0 给grid加载数据 问题

Question

Ext.define('CompanyModel', {
        extend:'Ext.data.Model',
        fields:[
            {name:'AutoID',type:'int'},
            {name:'CompanyNO',type:'string'},
            {name:'CompanyName',type:'string'},
            {name:'Tel',type:'string'},
            {name:'Address',type:'string'},
            {name:'AddressEng',type:'string'},
            {name:'Postcode',type:'string'},
            {name:'Re',type:'string'},
            {name:'Creator',type:'string'},
            {name:'CreatedTime',type:'string'},
            {name:'DeletedBy',type:'string'},
            {name:'DeletedTime',type:'string'},
            {name:'Deleted',type:'boolean'}
        ]
    });    var CompanyStore=Ext.create('Ext.data.Store',{
        model: 'CompanyModel',
    proxy: {
            type: 'ajax',
            url: 'listCompany.action',
            reader: {
                type: 'json',
                root: 'companylist'
            }
        },
    autoLoad: false
});
    CompanyStore.load();listCompany.action 可以执行companylist为：
[{Deleted=false, CreatedTime=2011-09-15 08:30:23.0, Creator=jet, Fax=123456, DeletedBy=null, CompanyNO=AA, CompanyName=AA, Postcode=123466, Address=上海, DeletedTime=null, AddressEng=shanghai, Re=null, AutoID=1, Tel=123456}]但是在js页面中的CompanyStore没有记录 

Answer 1

 root: 'companylist' 你的action得回的结果是
[companylist:[{Deleted=false, CreatedTime=2011-09-15 08:30:23.0, Creator=jet, Fax=123456, DeletedBy=null, CompanyNO=AA, CompanyName=AA, Postcode=123466, Address=上海, DeletedTime=null, AddressEng=shanghai, Re=null, AutoID=1, Tel=123456}]]
这样吗？

Answer 2

他的ACTION结果应该是
{companylist:[{Deleted=false, CreatedTime=2011-09-15 08:30:23.0, Creator=jet, Fax=123456, DeletedBy=null, CompanyNO=AA, CompanyName=AA, Postcode=123466, Address=上海, DeletedTime=null, AddressEng=shanghai, Re=null, AutoID=1, Tel=123456}]}

Answer 3

action 如下：public class CompanyListAction extends ActionSupport {
    public String execute() throws Exception {
        String strsql="select AutoID,CompanyNO,CompanyName,Tel,Fax,Address,AddressEng,\n"+
                "Postcode,Re,Creator,CreatedTime,DeletedBy,DeletedTime,Deleted from HR_Company where Deleted=0";
        List<Company> companylist=(List<Company>)getwlcspService().findBySQL(strsql);
        System.out.print("companylist------------"+companylist);
     return this.SUCCESS;
}
}

Answer 4

grid代码如下：
var companyGridPanel=Ext.create('Ext.grid.Panel', {
       id:'grid_companygridpanel_id',
       name:'grid_companygridpanel_name',
       loadMask: true,
       columnLines: true,
       disableSelection: false,
   renderTo:'CompanyList',
       store:CompanyStore,
   columns: [
           {header:'AutoID',dataIndex : 'AutoID'},
           {header:'CompanyNO',dataIndex : 'CompanyNO'},
           {header:'CompanyName',dataIndex:'CompanyName'},
           {header:'Tel',dataIndex:'Tel'}
       ]
});

Answer 5

'companylist':[
        { 'name': 'Lisa',  "email":"[email protected]",  "phone":"555-111-1224"  },
        { 'name': 'Bart',  "email":"[email protected]",  "phone":"555-222-1234" },
        { 'name': 'Homer', "email":"[email protected]",  "phone":"555-222-1244"  },
        { 'name': 'Marge', "email":"[email protected]", "phone":"555-222-1254"  }
    ]///参照此格式返回数据

Answer 6

public class CompanyListAction extends ActionSupport {
    public String execute() throws Exception {
        String companylist="[{ 'AutoID': 1,'CompanyNO':'GC','CompanyName':'GC','Tel':'123'}]";
     return this.SUCCESS;
}
}
我换成上面的数据源 还是加载不了

Answer 7

{companylist:[{Deleted=false, CreatedTime=2011-09-15 08:30:23.0, Creator=jet, Fax=123456, DeletedBy=null, CompanyNO=AA, CompanyName=AA, Postcode=123466, Address=上海, DeletedTime=null, AddressEng=shanghai, Re=null, AutoID=1, Tel=123456}]}最外面是大括号，不是方括号！！！

Answer 8

不好意思 第一次使用 structs  问题自己试出来了public class CompanyListAction extends ActionSupport {    
    private List<Company> companylist=new ArrayList();    public List<Company> getCompanylist() {
return companylist;
    }
        public String execute() throws Exception {
        String strsql="select AutoID,CompanyNO,CompanyName,Tel,Fax,Address,AddressEng,\n"+
                "Postcode,Re,Creator,CreatedTime,DeletedBy,DeletedTime,Deleted from HR_Company where Deleted=0";
        companylist=(List<Company>)getwlcspService().findBySQL(strsql);
        System.out.print("companylist------------"+companylist);     return this.SUCCESS;
}
}
