How do I remove letters and dashes and dollar signs in a string using a regular expression?

Question

I\'m trying to find all letters and dashes and dollar signs and remove them from a text box.

function numbersOnly()
{
    if ($(\'.sumit\').val().indexOf([A         


        

Answer 1

This worked for me:

$('.sumit').val().replace(/[^\d]/g, "");

I tried Mike's answer with the capital \D instead of negating a \d first which for some reason didn't remove parenthesis and other punctuation for me. Negating \d works perfect.

If you want to keep decimals, maybe put a dot and other symbols within the square brackets too.

PS The environment in which I tested was Titanium SDK.
