1. 定义
Events = function() {
var listen, log, obj, one, remove, trigger, __this;
obj = {};
__this = this;
listen = function( key, eventfn ) { //把简历扔盒子, key就是联系方式.
var stack, _ref; //stack是盒子
stack = ( _ref = obj[key] ) != null ? _ref : obj[ key ] = [];
return stack.push( eventfn );
};
one = function( key, eventfn ) {
remove( key );
return listen( key, eventfn );
};
remove = function( key ) {
var _ref;
return ( _ref = obj[key] ) != null ? _ref.length = 0 : void 0;
};
trigger = function() { //面试官打电话通知面试者
var fn, stack, _i, _len, _ref, key;
key = Array.prototype.shift.call( arguments );
stack = ( _ref = obj[ key ] ) != null ? _ref : obj[ key ] = [];
for ( _i = 0, _len = stack.length; _i < _len; _i++ ) {
fn = stack[ _i ];
if ( fn.apply( __this, arguments ) === false) {
return false;
}
}
return {
listen: listen,
one: one,
remove: remove,
trigger: trigger
}
}
2.使用
var adultTv = Event();
adultTv .listen( ‘‘play‘, function( data ){
alert ( "今天是谁的电影" + data.name );
});
//发布者
adultTv .trigger( ‘‘play‘, { ‘name‘: ‘麻生希‘ } )；
