How to remove periods in a string using jQuery

The first argument to replace() is usually a regular expression.

Use the global modifier:

$('#request_artist').val().replace(/\./g, "");

replace() at MDC

The method used to replace the string is not recursive, meaning once it found a matching char or string, it stop looking. U should use a regular expression replace.

$("#request_artist").val().replace(/\./g, '');
