ajax - Ext JS auto complete field with additional post variables -

i using ext js combobox in example: stackoverflow: how 1 html input tag autocomplete in ext.js?

it works perfect sending simple query on post server. (firebug output: query=smth)

but have bit different use case. want send additional information server. like: query=smth&variableid=8&somemore=xy.

of course add variables url of jsonstore , send on get. wondering if there params object can specify custom variables , considered request.

thank time.

yes. can define store with

baseparams: {    thiswillbeaddedtoeachrequest: 'foo' } 

or can use beforeload listener

listeners: {   beforeload: funciton(store) {     store.setbaseparam('paramtobesetbeforeeachrequest',somevariable);   } }
