javascript - Passing parameters to function before this.control() in Ext-JS 4 -


i have this:

{     listeners['combobox[name="counterparty_id"]'] = {         afterrender: {             fn: this.oncomboboxcounterpartyafterrender,             scope:         }     };            this.control(listeners); }    // function being called after rendering combobox  oncomboboxcounterpartyafterrender: function(combobox, eopts){  // code  },

so, how can send additional parameteres oncomboboxcounterpartyafterrender function?

maybe this:

listeners['combobox[name="counterparty_id"]'] = {             afterrender: {                 fn: this.oncomboboxcounterpartyafterrender,                 scope: this,                 params: someparameters             }         };

there might better way, can do:

listeners['combobox[name="counterparty_id"]'] = {     afterrender: {         fn: function(combobox, eopts) {             this.oncomboboxcounterpartyafterrender(combobox, eopts, params)         }         ...
