js remove dollar sign from string

1A common problem with HTML input forms is that users tend to include dollars signs when inputting currency numbers.
2These dollars signs can be easily removed through JavaScript by using the JavaScript replace function and a simple regular expression.
3This is demonstrated in the following example:
4
5var Amount = '$13.22';
6var ReplacedAmount = Amount.replace(/\$/g,'');
7document.write(ReplacedAmount);
