How do I replace non-numeric characters in string while excluding periods?

Question

So I have this-

lr_min = $('#lr_min').val().replace(/\D/g,'');

It gets rid of all the nonnumeric characters in the string. How do I exclude periods (.) from this replace?

Answer 1

You can use

lr_min = $('#lr_min').val().replace(/[^\d.]+/g,'');

The + isn't strictly necessary but will usually give better performances (less replacements)
