JavaScript custom Event Listener
event-listener, javascript
Solution
var evt = document.createEvent("Event");
evt.initEvent("myEvent",true,true);
// custom param
evt.foo = "bar";
//register
document.addEventListener("myEvent",myEventHandler,false);
//invoke
document.dispatchEvent(evt);
Here is the way to do it more locally, pinpointing listeners and publishers: http://www.kaizou.org/2010/03/generating-custom-javascript-events/
Problem
I was wondering if anyone can help me understand how exactly to create different Custom event listeners. I don't have a specific case of an event but I want to learn just in general how it is done, so I can apply it where it is needed. What I was looking to do, just incase some folks might need to know, was: ``` var position = 0; for(var i = 0; i < 10; i++) { position++; if((position + 1) % 4 == 0) { // do some functions } } ```
