Javascript：如何创建一个值之间有可变间隙的数组？

Question

I am trying to create an array with a variable gap between its values.

Eg.: supposing my gap equals 15, then my array will be [0, 15, 30, 45, 60].

This is what I have tried to do, but I couldn't make this work.

var min_array = 0;
var max_array = 60;
var gap = 15;

var arr = [];

while(min_array < max_array +1){
  arr.push(min_array+gap);
}

console.log(arr);

Answer 1

You have to count up min_array also with gap . Otherwise it will end in an infinity loop.

while(min_array < max_array){
  arr.push(min_array+gap);
  min_array += gap;
}

Answer 2

Edit your code to be like the code below , the problem with your code is that its runs for ever so you need to increase the min_array value every time you run the loop .

 var min_array = 0; var max_array = 60; var gap = 15; var arr = []; while(min_array < max_array) { min_array = min_array+gap arr.push( min_array); } console.log(arr); 

Answer 3

The previous answers are almost correct, but to include 0 do the following:

var min_array = 0;
var max_array = 60;
var gap = 15;

var arr = [];

while(min_array <= max_array){
  arr.push(min_array);
  min_array += gap;
}

console.log(arr);  // [0, 15, 30, 45, 60]

Answer 4

Also, just as a heads up, the JS for loop can also do this pretty easily.
See this for the documentation.

var arr = [];
for (var i = 0; i <= 60; i+=15) {
    // Parameters: the first argument is your min_array, the next is your max_array, and the final is your gap.
    arr.push(i);
}
