How jQuery implements custom events_jquery

The example in this article describes how jQuery implements custom events. Share it with everyone for your reference. The specific analysis is as follows:

jQuery is a very powerful tool. One of the very useful features of jQuery is the ability to implement event binding. You can create, bind events, and trigger your own defined jQuery events.

Custom event trigger

The code below is its custom event trigger. You can bind to this custom event.

$event.trigger("myEventName");

Custom event binding

The code below creates a binding to a custom event and will be executed when the custom event fires.

$(this).bind("myEventName",function(){
alert("myEventName triggered");
});

It can be seen that JQuery’s custom events are very useful.

I hope this article will be helpful to everyone’s jQuery programming.
