		+ parseFloat(document.getElementById("qty" + idx).value);



	document.getElementById("price" + idx).value = isNaN(price) ? "0.00" : price.toFixed(3);

}



function totalIt() {

	var qtys = document.getElementsByName("qty");

	var total = 0;

	for (var i = 1; i <= qtys.length; i++) {

		calc(i);

		var price = parseFloat(document.getElementById("price" + i).value);

Update parameter in function calc(idx, iscallTotalit). Add condition in function if (!iscallTotalit). Updatecalc(i, true); in totalit() function.

Edit

document.getElementById("cost" + idx).value || 0 Added || 0 at the end so if the value is null or empty then it will replace it with 0.

function calc(idx, iscallTotalit) {

	var cost = 0;

	var qty = 0;

	var del = 0;



	var price = parseFloat(document.getElementById("cost" + idx).value || 0)

Here is a simple example on how to handle the input directly:

const $source = document.querySelector('#source');

const $result = document.querySelector('#result');



const typeHandler = function(e) {

  $result.innerHTML = e.target.value; //Here you can handle the event, make your calculation and display the calculated data

}



$source.addEventListener('input', typeHandler) // register for oninput

$source.addEventListener('propertychange', typeHandler) // for IE8

<input id="source" />

<div id="result"></div>

Update parameter in function calc(idx, iscallTotalit). Add condition in function if (!iscallTotalit). Updatecalc(i, true); in totalit() function.

Edit

document.getElementById("cost" + idx).value || 0 Added || 0 at the end so if the value is null or empty then it will replace it with 0.

function calc(idx, iscallTotalit) {

	var cost = 0;

	var qty = 0;

	var del = 0;



	var price = parseFloat(document.getElementById("cost" + idx).value || 0)

		+ parseFloat(document.getElementById("del" + idx).value || 0)

		+ parseFloat(document.getElementById("qty" + idx).value || 0);



	document.getElementById("price" + idx).value = isNaN(price) ? "0.00" : price.toFixed(3);



	if (!iscallTotalit)

	    totalIt();

}



function totalIt() {

	var qtys = document.getElementsByName("qty");

	var total = 0;

	for (var i = 1; i <= qtys.length; i++) {

		calc(i, true);

		var price = parseFloat(document.getElementById("price" + i).value || 0);

		total += isNaN(price) ? 0 : price;

	}



	document.getElementById("total").value = isNaN(total) ? "0.00" : total.toFixed(3);

}





window.onload = function () {

Here is a simple example on how to handle the input directly:

const $source = document.querySelector('#source');

const $result = document.querySelector('#result');



const typeHandler = function(e) {

  $result.innerHTML = e.target.value; //Here you can handle the event, make your calculation and display the calculated data

}



$source.addEventListener('input', typeHandler) // register for oninput

$source.addEventListener('propertychange', typeHandler) // for IE8

<input id="source" />

<div id="result"></div>
