Use JavaScript toLocaleString method to convert the Locale string into a number.
An easy way to convert a string that might contain commas to a number is to find any non-digits within the string and remove it, thus, remaining with only digits.
var num = number.toLocaleString().replace(/\D/g,''); //1000000Locale string to number JavaScript
Simple example code.
<!DOCTYPE html>
<html>
<body>
<script>
var number = 1000000;
console.log('numeric number', number);
var str = number.toLocaleString();
console.log('with commas', str);
var num = str.replace(/\D/g,'');
console.log('string without commas', num);
var num2 = parseInt(num);
console.log('numeric', num2);
</script>
</body>
</html> Output:

How to convert String to Number according to locale JavaScript?
Answer: The following function will first construct a NumberFormat based on the given locale. Then it will try to find the decimal separator for that language.
Finally, it will replace all but the decimal separator in the given string, then replace the locale-dependant separator with the default dot and convert it into a number.
<script>
function convertNumber(num, locale) {
const { format } = new Intl.NumberFormat(locale);
const [, decimalSign] = /^0(.)1$/.exec(format(0.1));
return +num
.replace(new RegExp(`[^${decimalSign}\\d]`, 'g'), '')
.replace(decimalSign, '.');
};
console.log(convertNumber('100,45', 'de-DE'))
</script>Output: 100.45
