为元素添加trigger方法

[javascript]代码库

Element.prototype.trigger = function (type, data) {
    var event = document.createEvent('HTMLEvents');
    event.initEvent(type, true, true);
    event.data = data || {};
    event.eventName = type;
    event.target = this;
    this.dispatchEvent(event);
    return this;
};

NodeList.prototype.trigger = function (event) {
    []['forEach'].call(this, function (el) {
        el['trigger'](event);
    });
    return this;
};
