How can I change/add params on a store

Question

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

Ext.regStore(\'newsStore\',  {
    model: \'News\',
    autoLoad: true,
    proxy: {
        type: \'ajax\         


        

Answer 1

I suggest you a more elegant solution, the Sencha way to do that:

//Take your store
var store = Ext.StoreMgr.get('YOUR_STORE_ID');

//Apply the params
Ext.apply(store.getProxy().extraParams, {
    partyID: options.partyID,
    eventName: options.eventName
});

//Reload your store
store.contactInfoId.read();

Hope this helps.

You could try using extraParams:

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

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.

For dynamically setting extra parameters:

If you want to set single parameter at a time, you can use following

var proxy= myStore.getProxy();
proxy.setExtraParam('param1', 'value 1' );
proxy.setExtraParam('param2' , 'value 2' );
myStore.load();

If you want to set multiple parameters at a time, you can use following

proxy.setExtraParams({
     'param1':'value 1',
     'param2':'value 2'
});
