ext handler 中传递参数

				var btn = {
					xtype: 'tbbutton',
					text: apps[i].name,
					tooltip: apps[i].name,
					location : apps[i].location,
					handler: Application.openApplication, location: apps[i].location
				};

 则在 openApplication 方法中,会自动得到一个对象参数,这个对象包含属性 location,及其对应的属性值。如:

		openApplication: function(o){

			var url = 'http://' + host + ':' + port + o.location + '?sso=http://' + host + ':' + port;
			open(url, '_blank');
		}
