    Default Problems with a Store loading JSON Data

    Problems with a Store loading JSON Data


    Hello,

    sorry for that basic problem. But I'm very new to ExtJS. I've got a problem loading JSON Data provided by an php file into a store to display the data in a form.

    What I've done is this:

    Code:
    Ext.onReady(function () {
        
            store1 = new Ext.data.JsonStore({  
            url: 'data.php?data=1',  
            root: 'thedata',  
            fields: [{name:'data1',type:'float'}]
        });  
        
    store1.loadData();    
    
        
    });
    OK, this shows up an message in Firebug like this:

    Code:
    g is undefined
    (function(){var e=this,a=Object.protot...eate("Ext.XTemplate",j,g)}return j}});
    g is undifined. Oh yes, tells me nothing.

    My JSON looks like this:

    Code:
    {"thedata":{"data1":1.22}}
    Where did it go wrong?

    Thanks for any hint!

    KJH

    Your life will be easier if you (for now) use ext-all-debug.js - it's not minified, so "g" would actually be a meaningful reference.

    As for your store, can you try something like this?

    PHP Code:
    Ext.define('MyModel', {
        
    fields: [
            { 
    name'data1'type'float' }
        ]
    });

    var 
    store1Ext.create('Ext.data.Store', {
        
    model'MyModel'
        
    autoLoadtrue
        
    proxy: {
            
    type'ajax'
            
    url'data.php?data=1',
            , 
    reader: {
                
    type'json'
                
    root'thedata'
            
    }
        }
    });

    You are using ExtJS 4? IMHO there is no JsonStore anymore.

    The stores still exist in the sources (ExtJS package src/data/JsonStore.js). They're not in the docs though.
