i want to remove comma from a number (e.g change 1,125 to 1125 ) in a .tpl file. The value comes dynamically like ${variableMap[key]}

var a='1,125';
a=a.replace(/\,/g,''); // 1125, but a string, so convert it to number
a=parseInt(a,10);

Hope it helps.

You can use the below function. This function can also handle larger numbers like 123,123,123.

function removeCommas(str) {
    while (str.search(",") >= 0) {
        str = (str + "").replace(',', '');
    }
    return str;
};

var s = '1,125';
s = s.split(',').join('');

Hope that helps.

You can use Regular Expression to change as it is faster than split join

var s = '1,125';
s = s.replace(/,/g, '');

//output 1125

Incoming value may not always be a string. If the incoming value is a numeric the replace method won't be available and you'll get an error. Suggest using isNaN to see if numeric, then assume string and do replacement otherwise.

if(isNaN(x)) {
    x = parseInt(x.replace(/[,]/g,''));
}

(Not foolproof because 'not number' doesn't prove it is a string, but unless you're doing something very weird should be good enough). You can also add other symbols to the character group to remove other stray chars (such as currency symbols).

✨ ES2021 ✨ added replaceAll, so no need for regular expression:

const str = '1,125.05';
const number = parseFloat(str.replaceAll(",", ""));
