electronvolt v1.0.2

eV

The eV (electronvolt) provides a simple DOM-like event system.

Installation

$ npm install electronvolt

Example

var ev = require("electronvolt");

// create event nodes
var node = new ev.EventNode();
var parent = new ev.EventNode();

// compose event flow
node.parentNode = parent;

var listener = function (event) {
    switch (event.eventPhase) {
        case ev.EventPhase.AT_TARGET:
            console.log("at target");
            break;
        case ev.EventPhase.BUBBLING_PHASE:
            console.log("bubbling phase");
            break;
        case ev.EventPhase.CAPTURING_PHASE:
            console.log("capturing phase");
            break;
    }
};

// add event listeners
node.addEventListener("example", listener);
parent.addEventListener("example", listener);
parent.addEventListener("example", listener, true);

// dispatch event into the event flow
node.dispatchEvent(new ev.Event("example", true));
// -> capturing phase
// -> at target
// -> bubbling phase
