The following can be used in JavaScript to remove all commas from a number:
var StartNumber = ‘444,555,666‘;
var ReplacedNumber = StartNumber.replace(/\,/g,‘‘);
document.write(ReplacedNumber);
The preceding example uses the JavaScript replace function and utilizes a regular expression to replace all the commas in a number. In the regular expression, the backslash (\) before the comma is used as an escape character, meaning that the comma should be treated as a literal comma. The ‘g‘ means that the replace should be applied globally. Without this, only the first comma would be removed.
