如何使用 jquery 在随机秒后将数字增加 1？

Question

Is there any way to increase a number by 1 after random seconds. For example, the base value is 10. So it will change by 1 after a random seconds(ie. 1/2/3/4/5 seconds randomly).

i have tried like this:

var startVal = 10;
setInterval(function(){
    var theVal = startVal + 1; 
    startVal = theVal;
}, Math.round(Math.random() * (6000 - 2000)) + 2000);

Number is increasing but the time is not random. Please help.

Answer 1

Here is a working example. Will raise the number by one after 0,1 or 2 seconds

let number = 10;

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}
function addNumber() {
  number++;
  console.log(number)
}
setTimeout(addNumber, getRandomInt(3) * 1000)

Answer 2

If you want the time to change on each iteration, you will need to use setTimeout.

 var startVal = 10; function increase() { setTimeout(function(){ var theVal = startVal + 1; startVal = theVal; increase(); console.log(startVal); }, Math.round(Math.random() * (6000 - 2000)) + 2000); } increase()
