Multiple event

We can combine multiple events and run the same code. Each event has to be separated by a space.

$('#id_dtl').bind('blur keyup', function(){
// Your code here
});
Here either blur or keyup any one event can fire the code inside.

How to identify which event has occurred

We can use e.type to get the details of the event.
$("#b1").on('dblclick click',function(e){
$("#t1").html('Your type of Click event  : '+e.type);
});
