Question

Let’s suppose I have this this simple button:

{
   xtype :'button',
   text :'button',
   id:'address'+counter.no,
   handler : function() {}
}

How can I get access to the current button and get access to its properties such as name, id, etc?

I’m aware of Ext.getCmp('compid') but I need to get access to CURRENT button, and I don’t know its id.

Answer 1

Do you mean inside the handler function?

See docs at description for handler.
As first parameter this button object is passed, so you could do the following:

{
   xtype :'button',
   text :'button',
   id:'address'+counter.no,
   handler : function(thisButton, eventObject) {
       //Do something with thisButton like:
       alert(thisButton.getId());
   }
}
