Val.replace (/ [^ a-zA-Z_-0-9] / g, '') raises SyntaxError: invalid range in character class

Question

I need to replace all characters that do not match the range a-zA-Z_-0-9 . So I am doing val.replace(/[^a-zA-Z_-0-9]/g, '') but I get an error. How can I bite this? Thanks

Answer 1

If you want to include the minus sign “-” in the character class, you must put it at the end of the range:

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

Answer 2

I would prefer this regex:

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

Answer 3

Character - considered as an alphabetic character if it is the last or first (after the ^ character) in brackets.

Answer 4

You expect the - character - be parsed as a literal, but it is parsed as a range: _-0 means _ to 0 , just as az means a to z . However, since _ has a higher character code than 0 , you get an error message.

In your case, just run away from it: \- . This is parsed as a - symbol.

Answer 5

You have a bad range, delete - between _ and a range of numbers, and put it at the end or the beginning.

Answer 6

try the following:

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

Answer 7

You need to avoid the "-"

 val.replace(/[^a-zA-Z_\-0-9]/g, '') 

Answer 8

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