On a sencha-touch, here\'s is my store declaration
Ext.regStore(\'newsStore\', {
model: \'News\',
autoLoad: true,
proxy: {
type: \'ajax\
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'
});
