Add "OnSelect" event listner, without override the existing event listner

[Shon]

Hello dear friends,

I am trying to add another event listner for "onSelect" event without overriding the existing one, but i dont know thow to do this.

I initialize the combogrid like this:
jobjInput.combogrid({
            url: strUrl,
            mode: 'remote',
            .....
            onSelect: function() { ... }
});

and after that trying to add another event listner to the input like this:
jobjInput.combogrid({ onSelect: function() { ... } });

but if i do it in this way, the original "onSelect" event not raised.

apperantly there is another way to add event listener, can you please direct me what is the way? I searched the web without success

Thank u very much,
Shon

Please try to extend the 'attachEvent' method for the combogrid component.

Code:

$.extend($.fn.combogrid.methods, {
	attachEvent: function(jq, param){
		return jq.each(function(){
			var grid = $(this).combogrid('grid');
			var opts = $(this).combogrid('options');
			opts.handlers = opts.handlers || {};
			var cbs = opts.handlers[param.event];
			if (cbs){
				cbs.push(param.handler);
			} else {
				cbs = [opts[param.event], param.handler];
			}
			opts.handlers[param.event] = cbs;
			opts[param.event] = grid.datagrid('options')[param.event] = function(){
				var target = this;
				var args = arguments;
				$.each(opts.handlers[param.event], function(i,h){
					h.apply(target, args);
				})
			}
		})
	}
})

Call 'attachEvent' method to add your own event handler.

Code:

jobjInput.combogrid('attachEvent',{
  event: 'onSelect',
  handler: function(index,row){
    //...
  }
});

thanks stowrthy for the extended method. but it's not working when i try other event like 'onChange',

Code:

$(zone_id_dest.target).combogrid('attachEvent',{
          event: 'onChange',
          handler: function(nv,ov){
            console.log(nv);
          } 
        });

i check the console but it won't show up.

thanks
