I have my DOM like this :
<input type="number" id="input" value="" placeholder="Enter time in minutes">
<button id="button">Go</button>
<button id="reset">reset</button>
<div class="timer">
<div class="mint" id="mint"></div>
<div class="sec" id="sec"></div>
</div>
And my JavaScript Like this :
let currentTime = 0;
let intervalClear;
let input = document.getElementById('input');
let button = document.getElementById('button')
button.addEventListener('click', ()=>{
let value = input.value * 60000;
function getTime(){
currentTime
function backcount(currentTime){
let output = value - currentTime
console.log(output);
const mint = document.getElementById('mint'),
sec = document.getElementById('sec');
let minute = Math.floor(output/60000)
let second = ((output % 60000) / 1000).toFixed(0)
mint.innerText = minute;
sec.innerText = second;
if(output == 0){
clearInterval(intervalClear)
}
}
backcount(currentTime);
}
getTime()
intervalClear = setInterval(getTime, 1000)
})
const reset = document.getElementById('reset')
reset.addEventListener('click', ()=>{
clearInterval(intervalClear);
input.value = '';
})
now I want to display value in my web page But it doesn't updating. seems like its freezes. but my "setInterval()" running properly.
How can I resolve this issue? need help!

You need instead of this code
let output = value - currentTime
use this
let output = value - (currentTime * 1000)
let currentTime = 0;
let intervalClear;
let input = document.getElementById('input');
let button = document.getElementById('button')
button.addEventListener('click', ()=>{
let value = input.value * 60000;
function getTime(){
currentTime
function backcount(currentTime){
let output = value - (currentTime * 1000)
console.log(output);
const mint = document.getElementById('mint'),
sec = document.getElementById('sec');
let minute = Math.floor(output/60000)
let second = ((output % 60000) / 1000).toFixed(0)
mint.innerText = minute;
sec.innerText = second;
if(output == 0){
clearInterval(intervalClear)
}
}
backcount(currentTime);
}
getTime()
intervalClear = setInterval(getTime, 1000)
})
const reset = document.getElementById('reset')
reset.addEventListener('click', ()=>{
clearInterval(intervalClear);
input.value = '';
})
