const designated = "1 jan 2021"

function countdown(designated_time){

    const currentTime = new Date();
    const future_time = new Date(designated_time);
    console.log(future_time - currentTime);
}

countdown(designated);

setInterval(countdown, 1000, designated);

有很多方法可以做到这一点，我个人认为这是干净和甜蜜的。

你可以使用匿名函数;

setInterval(function() { funca(10,3); },500);

这个问题的最佳解决方案是下一段代码:

setInterval(() => yourFunction(param1, param2), 1000);

我知道这个话题是如此古老，但这是我的解决方案传递参数在setInterval函数。

Html:

var fiveMinutes = 60 * 2;
var display = document.querySelector('#timer');
startTimer(fiveMinutes, display);

JavaScript:

function startTimer(duration, display) {
    var timer = duration,
        minutes, seconds;

    setInterval(function () {
        minutes = parseInt(timer / 60, 10);
        seconds = parseInt(timer % 60, 10);

        minutes = minutes < 10 ? "0" + minutes : minutes;
        seconds = seconds < 10 ? "0" + seconds : seconds;

        display.textContent = minutes + ":" + seconds;
        --timer; // put boolean value for minus values.

    }, 1000);
}

     setInterval(function(a,b,c){

          console.log(a + b +c);  

      }, 500, 1,2,3);

           //note the console will  print 6
          //here we are passing 1,2,3 for a,b,c arguments
         // tested in node v 8.11 and chrome 69

另一个解决方案是像这样传递你的函数(如果你有动态变量): setInterval(“funca (' + x + ', ' + y + ') ', 500);
