    Question Proxy not working with type 'jsonp' !!!

    Proxy not working with type 'jsonp' !!!


    Hi All,

    I was tried to use proxy with type 'jsonp' in a store. But I'm getting an error like as follows,
    "Uncaught SyntaxError: Unexpected token :"

    I am using ST2.0 with MVC pattern. The code which I wrote is given below:

    Code:
    Store
    -------------
    Ext.define('Sencha.store.Latestarticles', {
        extend  : 'Ext.data.Store',
        model   : 'Sencha.model.Latestarticles',
        requires: ['Sencha.model.Latestarticles'],
        
        proxy : {
            type : 'jsonp',
            url : 'http://192.168.8.128/magazine/getlatestarticles.php',
            reader : {
              type : 'json',
              root : 'articles',
              totalCount : 'total'
            }
        },
        autoLoad: true
    });
    
    Model
    -----------
    Ext.define('Sencha.model.Latestarticles', {
        extend: 'Ext.data.Model',
    
        fields: [
            {name: "articleid", type: "number"},
            {name: "catogery", type: "string"},
            {name: "image", type: "string"},
            {name: "title", type: "string"}       
        ]
    });
    
    
    Response
    ----------------
    {"success":true,"total":10,"articles":[{"articleid":"24","catogery":"CARS, BIKES, BOATS & PLANES","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/n1_0.jpg","title":"The man behind Ferrari's new<br\/>tailor made service"},{"articleid":"21","catogery":"SPORT","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/sachin.jpg","title":"Sachin Tendulkar - The legend"},{"articleid":"16","catogery":"HOUSE & GARDEN","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/mn1.jpg","title":"How does a garden really grow?"},{"articleid":"14","catogery":"ART & COLLECTING","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/art.jpeg","title":"A torrent of new work from a<br\/>late-flowering artist"},{"articleid":"18","catogery":"WATCHES & JEWELLERY","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/wtc.jpg","title":"It's the ultimate selection of<br\/>fine watches"},{"articleid":"20","catogery":"HEALTH & GROOMING","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/art.jpg","title":"Spa junkie at... bodyism"},{"articleid":"17","catogery":"LIFESTYLE","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/n1.jpg","title":"The Aesthete"},{"articleid":"23","catogery":"PHILANTHROPY","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/mn1_0.jpg","title":"Where are India's great<br\/>philanthropists?"},{"articleid":"19","catogery":"FASHION","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/n3.jpg","title":"Confessions of a Boden addict"},{"articleid":"22","catogery":"FOOD & DRINK","image":"http:\/\/192.168.8.128\/bo-magazine\/sites\/default\/files\/kp.jpg","title":"Super delicious food in an<br\/>cool restaurant"}]}

    Default


    you're forgetting the callback function.
    use the parameter
    callbackKey: ' myCallback'

    on server side, concat the json with your callback function, passed by GET
    php example:

    echo $_GET['myCallback']."(". json_encode(your_json). ")";
