    setTimeout(function() {
        d.resolve("first");
    }, 1000);
    return d;
};
var asyncFunc2 = function() {
    var d = Promise.defer();
    setTimeout(function() {
        d.resolve("second");
    }, 1000);
    return d;
}

Promise.when(asyncFunc1, asyncFunc2)
.then(function(results) {
    console.log(results[0]); // "first"
    console.log(results[1]); // "second"
});
</script>

}, 2000);
.next(function(res) {
    console.log(res); // call after more 2000ms, and res is "ok"
}, 2000);
