How can I pad a value with leading zeros when value equals to one digit number?-CodePudding

I want to convert seconds into minutes. For example 61 seconds should be displayed like 1:01 (not 1:1) I tried with parseInt(sec / 60) : sec % 60. If sec=61 it is showing like 1:1.

I have data from music API that gives me music duration in seconds and I have to convert them into minutes. I tried

{parseInt(data.duration / 60 )} : {data.duration % 60}

sometimes it is giving me 3:35, 3:24 and 3:1. I have to add 0 before 1 as well. How can I do it I also tried with

{parseInt(data.duration / 60 )} : {parseFloat(data.duration % 60).toFixed(2)}

it is showing 1:1.00 I want to display it like 1:01.

Thank you for your help in advance.

function parseTime(time) {
    const minutes = Math.floor(time / 60);
    const second = time % 60;
    // return `${minutes}:${second < 10 ? "0" : ""}${second}`;
    return `${minutes}:${second.toString().padStart(2, "0")}`;
}

You can use the if else statement to verify the second or use padStart to make sure the length of the second is always 2.

try this

const convertToTime = (time) => (time < 10 ? `0${time}` : time);

const sec = 69;
const result = `${convertToTime(parseInt(sec / 60))}:${convertToTime(sec % 60)}`;;

console.log(result);

Thank you all for your support. I found the answer. Thank to @ace1234

{parseInt(data.duration / 60)} : {parseFloat(data.duration % 60 ).toString().padStart(2, "0")

CodePudding user response：

You can write a logic to handle it or use padStart

const something = 7;

const fun1 = (s) => s < 10 ? `0${s}` : s;
const fun2 = (s) => s.toString().padStart(2, '0');

console.log( fun1(something) );
console.log( fun2(something) );

Do it like

let min = sec/60;

And display like

min: sec - (min*60)
