我被引导相信Promise.all会并行执行你传递它的所有函数,而不关心返回的promises完成的顺序.

但是当我写这个测试代码时:

function Promise1(){
    return new Promise(function(resolve, reject){
        for(let i = 0; i < 10; i++){
            console.log("Done Err!");
        }
        resolve(true)
    })
}

function Promise2(){
    return new Promise(function(resolve, reject){
        for(let i = 0; i < 10; i++){
            console.log("Done True!");
        }
        resolve(true)
    })
}

Promise.all([ 
    Promise1(),
    Promise2()
])
.then(function(){
    console.log("All Done!")
})

我得到的结果就是这个

Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done Err!
Done True!
Done True!
Done True!
Done True!
Done …

我正在为我的键盘修改一些驱动程序软件,其中一部分是将日期输出到键盘屏幕的插件.目前它说1月1日,但我真的希望它说第1,第2,第3或第4或其他什么.

我一直在寻找各种代码,这些代码会给我一些关于如何做到这一点的想法,但我只能找到C#的例子而且我正在使用C.

const char *ordinals[] = {"", "1st", "2nd", "3rd", "4th", "5th", "6th", "7th", "8th", "9th", "10th", "11th", "12th", "13th", "14th", "15th", "16th", "17th", "18th", "19th", "20th", "21st", "22nd", "23rd", "24th", "25th", "26th", "27th", "28th", "29th", "30th", "31st"};

sprintf(date, "%s %s", ordinals[t->tm_mday], mon);
