Question

所以我一直在为我的番茄钟（番茄）时钟调试我的脚本。我希望这个脚本做的是它将收到输入（在几分钟内）。现在我的脚本正在做的是倒数5而不是1秒。它也不会像我想要的那样显示分钟。

我以合理的方式编写脚本以登录到控制台并对其进行测试。我在控制台中看到的是它每秒显示一次，但如果有意义则每秒显示5秒。这是jsbin：https://jsbin.com/gigohajawo/3/edit?js,consolehttps://jsbin.com/gigohajawo/3/edit?js,console

这是代码，任何帮助将不胜感激!!!

//makes sure the page is loaded first
$(document).ready(function() {
    //global variables
    //grabs text of an id and converts it to an int
    var countMin = 5;
    var count1 = 60;


    //when button id "but" is clicked...

       //while page is up, it keeps track each second that has passed
       for(; countMin >=0;countMin--){
            var counter1 = setInterval(function(){
                //calls timer function to count down
                 count1 = Timer(count1,counter1,countMin);
            },1000);
          count1 =60;
        }



    //counts down
    function Timer(count,counter,minutes){
        count--;
        //once it hits 0 seconds, the interval will stop counting
        if(count <=0){
            clearInterval(counter); 
            return count;
        }

        //displays the countdown
        if(minutes < 10){
            if(count < 10){
                console.log("0:0" + count);
            } else {
                console.log("0:" + count);
            }
        }else if(minutes > 0 && minutes < 10){
            if(count < 10){
                console.log("0" + minutes +":0" + count);
            } else {
               console.log("0"+minutes+":" + count);
            }
        } else{
            if(count < 10){
                console.log(minutes+":0" + count);
            } else {
               console.log=minutes+":" + count;
            }
        }

        return count;
    }

This JSBin似乎按照你的意图行事。

代码：

//makes sure the page is loaded first
$(document).ready(function() {
    //global variables
    //grabs text of an id and converts it to an int
    var count1 = 120;

    // Call a function every 1000 milliseconds (1 second)
    var counter1 = setInterval(function() {
      count1 = Timer(count1, counter1);
    }, 1000);


    //counts down
    function Timer(count,counter){
        // Decrement the seconds counter
        count--;

        // Get the minutes and seconds in whole numbers
        var minutes = Math.floor(count / 60);
        var seconds = count % 60;

        // Once it hits 0 seconds, the interval will stop counting
        if(count <=0){
            clearInterval(counter);     
        }

        // Pads the seconds with a 0
        if (seconds < 10) {
          seconds = "0" + seconds;
        }

        // Pads the minutes with a 0
        if (minutes < 10) {
          minutes = "0" + minutes;
        }

        //displays the countdown
        console.log(minutes + ":" + seconds)

        return count;
    }

});

请注意：

由于您已将count1定义为全局变量，因此无需将其传递给Timer
counter1

如果我改写它，我会做这样的事情：

//makes sure the page is loaded first
$(document).ready(function() {
    var timeInSeconds = 120;

    var timeCounter = setInterval(function() {
      timeInSeconds--;

      // If we hit 0 seconds clear the timer
      if (timeInSeconds <= 0) {
        clearInterval(timeCounter);
      }

      // Display the current time
      displayTime();
    }, 1000);


    function displayTime(){
        // Get the minutes and seconds in whole numbers
        var minutes = Math.floor(timeInSeconds / 60);
        var seconds = timeInSeconds % 60;

        // Pad with zeros using the Ternary operator
        seconds = (seconds < 10) ? "0" + seconds : seconds;
        minutes = (minutes < 10) ? "0" + minutes : minutes;

        // Display the countdown
        console.log(minutes + ":" + seconds)
    }

});

CountDown脚本，无法正确显示或倒计时
