    Get data from complicated JSON


    How to get data (I need ID and Name) from this JSON:
    Code:
    {"d" : {
    "results": [
    {
    "__metadata": {
    "uri": "http://localhost:2376/WebApp/0/ServiceModel/EntityDataService.svc/AccountCollection(guid'42ce8b78-167e-4ce0-b971-000ec687a4ac')", "type": "Noname.Configuration.Account"

    }
    }, "PrimaryContact": {

    }
    }, "Code": "", "Type": {
    "__deferred": {

    }
    }, "AccountCategory": {

    }
    }, "EmployeesNumber": {

    }
    }, "AnnualRevenue": {
    "__deferred": {
    "uri": "http://localhost:2376/WebApp/0/ServiceModel/EntityDataService.svc/AccountCollection(guid'42ce8b78-167e-4ce0-b971-000ec687a4ac')/AnnualRevenue"
    }
    }, "Notes": "", "Logo": {
    "__deferred": {

    }
    }, "AlternativeName": ""
    }
    ]
    }
    }
    Now I try to do it so:
    Code:
    Ext.regModel('JSONData', {            fields: ['ID', 'Name']
            });
            var JSONStore = new Ext.data.Store({
                model: 'JSONData',
                proxy: {
                    type: 'ajax',
                    headers: {
                        'Accept': 'application/json',
                        'Authorization': 'Basic ' + Ext.util.base64.encode('TestUser:TestUserPass')
                    },
                    url: 'ServiceModel/EntityDataService.svc/AccountCollection',
                    reader: {
                        type: 'json',
                        root: 'd'
                    }
                },
                autoLoad: true
            });
    But I get nothing (of course), cause node 'd' has another subnode 'results'. And only it has useful data. How to parse it correctly using reader of store (or another variant)?

    First Ext.regModel is deprecated, you should use Ext.define instead.

    Second, root config has been renamed to rootProperty.

    Third, you should assign rootProperty to 'd.results'
