Question

var rand;
var count = 0;

function gimmeRandom();
{

    rand = Math.floor(Math.random()*10)+1;
    count++;
    return(gimmeRandom);
}

function countToRandom();
{
    var count;
    for(count = 1; count <= rand; count++)
 {
    console.log(count);
 }

}

console.log("counting to a random number");
gimmeRandom();
countToRandom();
console.log("counting to another random number");
gimmeRandom();
countToRandom();
console.log(there has been "+count+" random numbers");

所以我需要的帮助是使用这段代码，但让countToRandom接受一个参数，然后计算参数中提供的值。

谢谢，

Answer 1

function countToRandom(count) {
    for(var i = 1; i <= count; i++)
    {
        console.log(i);
    }
}

countToRandom(15);

Answer 2

代码正在运行。只需删除分号和第一个函数中的return-statement。

<强>缩短

var rand;
var count = 0;

function gimmeRandom() {
  rand = Math.floor(Math.random() * 10) + 1;
  console.log("rand", rand);
  count++;
}

function countToRandom() {
  for (var i = 1; i <= rand; i++) {
    console.log(i);
  }
}

console.log("counting to a random number");
gimmeRandom();
countToRandom();
console.log("counting to another random number");
gimmeRandom();
countToRandom();
console.log("there has been " + count + " random numbers");

Answer 3

    var rand;
    var count = 0;

    function gimmeRandom()
    {
      var rand = Math.floor(Math.random()*10)+1;
      return(rand);
    }

    function countToRandom(rand,count)
    { 
      for(var i = 1; i <= rand; i++)
      {
       console.log(i);
      }
       count++;
       return(count);
     }

console.log("counting to a random number");
rand = gimmeRandom();
count = countToRandom(rand,count);
console.log("counting to another random number");
rand = gimmeRandom();
count = countToRandom(rand,count);
console.log("there has been "+count+" random numbers");

countToRandom（）接受参数
