Matching numbers with regular expressions — only digits and commas

Question

I can\'t figure out how to construct a regex for the example values:

123,456,789
-12,34
1234
-8

Could you help me?

Answer 1

Try this:

    boxValue = boxValue.replace(/[^0-9\.\,]/g, "");

This RegEx will match only digits, dots, and commas.
