Question

On a sencha-touch, here’s is my store declaration

Ext.regStore('newsStore',  {
    model: 'News',
    autoLoad: true,
    proxy: {
        type: 'ajax',
        url: '../news/list.form?format=json',
        reader: {
            type: 'json',
            root: ''
        }
    },                        
});

How can I modify params? I tried

params:{ format: 'json'}

But its doesn’t work!

Store declaration

new Ext.data.Store({
model:'prj.models.ContactInfo',
storeId:'contactInfoId',
proxy:{
    type:'ajax',
    url:'/GetContactInfoByID',
    reader:{
        type:'json'
    },
    extraParams:{
        format:'json'
    },
    listeners:{
        exception:function(proxy, response, orientation){
            console.error('Failure Notification', response.responseText);
            Ext.Msg.alert('Loading failed', response.statusText);
        }
    }
}   
});

Adding params to proxy and read ajax store

prj.stores.contactInfoId.getProxy().extraParams.partyID = options.partyID;
prj.stores.contactInfoId.getProxy().extraParams.eventName = options.eventName;
prj.stores.contactInfoId.read();

Hope this helps.
