定时器函数

定义一个定时器

var setTimer = function(fn, interval) {
    var recurse, ref;
    ref = {};
    ref["continue"] = true;
    (recurse = function() {
        if (ref["continue"]) {
            ref.timeout = setTimeout((function() {
                fn();
                recurse();
            }), interval);
        }
    })();
    return ref;
}

清除定时器

var clearTimer = function(ref) {
    ref["continue"] = false;
    clearTimeout(ref.timeout);
}
