var store = new Ext.data.JsonStore({
                                                id:'jfields',
                                                totalProperty:'totalcount',
                                                root:'rows',
                                                url: 'data.php',  
                                                fields:[{ name:'jfields' },
                                                        { name:'firstyear' , mapping :'firstyear' , type:'float' },
                                                        { name:'secondyear', mapping :'secondyear', type:'float' },
                                                        { name:'thirdyear' , mapping :'thirdyear' , type:'float' },
                                                        { name:'fourthyear', mapping :'fourthyear', type:'float' },
                                                        { name:'fifthyear' , mapping :'fifthyear' , type:'float' } ]

                                                }                                                   
                                            });

what i want is to add data at the end for this store , but i am totally confused , what i did is i add the following code to it but not working.
listeners:{ load : function(){ BG_store.add([{"jfields":"Monthly","firstyear":22.99,"secondyear":21.88,"thirdyear":21.88,"fourthyear":22.99,"fifthyear":21.88}]); } But i do not think my concept are cleared ,Please any body show some way how to do it .

Answer 1

You need to define a record type, create it and at it, e.g:

TaskLocation = Ext.data.Record.create([
    {name: "id", type: "string"},
    {name: "type", type: "string"},
    {name: "type_data", type: "string"},
    {name: "display_value", type: "string"}
]);

Then:

var record = new TaskLocation({
    id: Ext.id(),
    type: "city",
    type_data: "",
    display_value: "Brighton"
});

Then:

my_store.add(record);
my_store.commitChanges();

Remember by the time the data is in the store it's not in the same format as you sent it down but in Record objects instead.

Hi guys , I have also figured out a simple solution to this ----> listeners:{ load: function( xstore , record , option ) { var u = new xstore.recordType({ jfields : 'monthly' }); xstore.insert(record.length, u); }

Here what i have to add is this listeners as when the data loads it will create the record type and u can add fields as data as many as u want
