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 .

extjs
