Yes, you can do this but this is based on the parameters provided by the caller of the handler. In case of it button this would be the 'click' event. But you can always view all passed arguments when reading the arguments array like

handler:function(){
    console.log(arguments);
}

and if you know that there is for example one argument you know you (lets take the button) can define it

handler:function(btn){
    btn.disable();
}

You also need to know that alert is not capable of printing JavaScript Objects! Use console.log for this.

@BurhanMughal Then you should alter your question cause no one will know what you are trying to archive and what I wrote is is correct in the context you asked the question. I must say that I can't follow you so you should really alter your question. And Kindly change your second answer to first one what do you mean by that?
