is to possible to attach custom events to the document's body? I wanna implement a simple message bus. I did it many times with jQuery, but not sure how to do it in ExtJS.
Thank you.
You don't need to attach the event to the body or any DOM element, I would rather attach them to a dedicated object.
Like :
MyApp.MessageBus = Ext.extend(Ext.util.Observable, {
// I don't think it's necessary to declare all events
events : {
sayHello : true
}
});
MsgBus = new MyApp.MessageBus();
And, somewhere in your code :
MsgBus.on('sayHello', function(who) { alert("Hello, " + who); });
And, on another place :
MsgBus.fireEvent('sayHello', 'innerJL');
