Question

I need to replace all chars which are not match with range a-zA-Z_-0-9. So I do val.replace(/[^a-zA-Z_-0-9]/g, \'\') but get error. How can I bit t

Answer 1

try this:

val.replace(/[^a-zA-Z_0-9-]/g, '');

Answer 2

The - character is treated as a literal character if it is the last or the first (after the ^) character within the brackets.

Answer 3

$(this).val($(this).val().replace(/[^a-zA-Z_0-9-]/g, ''));

Answer 4

You have a bad range, remove the - between _ and the number range and put it at the end or at the beginning.

Answer 5

I would prefer this regex:

val.replace(/[^\w-]+/gi, "");

Answer 6

If you want to include the minus sign "-" in the character class, you have to put it into the end of range:

val.replace(/[^a-zA-Z_0-9-]/g, '')
