I'll start by saying I know virtually nothing about Javascript, beyond a broad idea of where it goes and what it does.

I have a small problem in terms of getting a form submitted to my action page (which, if relevant, is programmed in Coldfusion). The text field may contain certain characters that I need to replace before they hit the action page. For example, the user may enter something like 'Save 5.00'. I therefore need to change the '' to '£' - but I need to do this before the form is submitted.

My gut feeling is this is a job for Javascript - can anyone enlighten me please?
