I need a JavaScript code that would perform a function after a countdown of a value assigned to a variable

Question

Like var a = Number(document.getElementById('cD').value)
Html
***********************
<input type='text' id='cD' />
***********************

So that when I enter value 5, it counts down to 0 and performs the task I want it to.

Thanks in advance..... 🤘🤘🤘

Answer 1

function count_down(n, callback){
if(n >= 0) return callback()
setTimeout(count_down(n - 1), 1000)
console.log(n)
}
your_input_element.oninput = () => {
count_down(Number(your_input_element.value), your_function)
}

I just have typed this so I don't know if it works, but you can try 😃
