Hi Sword,do you know why i get the error ' records.get is not a function ' when i try to use the function that belongs to Ext.data.Record?

[sword-it]

Hi,

you can try this:

 for(var i=0; i< records.length;i++){
    records[i].get('propertyname');
}

Hi Sword,the function 'get' works now according to what u said.but still cant get the data.
like

records[0].get('groups') ;//undefined

[sword-it]

Hi,

you can use like this one:

records[0].get('group1')

[Baron89]

Hi,

you can use like this one:

records[0].get('group1')

Hi，I finally get the data like below
record[0].get('data1')
let me show you my store code

 var WorkOrderRecord = Ext.data.Record.create([
     {name: 'data1'}  ]);
  myStore = Ext.extend(Ext.ux.MultiGroupingStore, {
    constructor: function(cfg) {
        cfg = cfg || {};
        myStore.superclass.constructor.call(this, Ext.apply({
            
            proxy: new Ext.data.HttpProxy({
             method: 'POST',
             url: '**/test.json'
            }),
            autoLoad: false,   
            
            reader: new Ext.data.JsonReader({
            root: 'rows',
            successProperty: 'success',
            messageProperty: 'message',
            totalProperty: 'total',         
    
   },
   WorkOrderRecord    
   )
 }));
    }
});

Providing your root config in the beginning would've helped

I really would recommend using Firebug and the console.log() function, since this would've helped you to see exactly what type of object records was, and what the child names are.

Hey buddy,how to use firebug to see the child names of records?

[willigogs]

console.log(records)
