Question

I want to add char code this to prevent in my JS form. This JS not working if I add this char code :

] \ /

—

jQuery.validator.addMethod("userNameRule", function(string, element) { 
    return !string.match(/[.;,`~!@#$%^&*()-+=|{[}'":?><]/g);
    });

What I want to do now is, add that the char code into my JS.

So how can I do that?

Answer 1

your pattern contains some reserved characters like . ^ $ ( ) { } - + ?

In a character class you should only escape the - anyway, because it is intended for range of symbols like a-z or 0-9

try to escape them like so

return !string.match(/[\.;,`~!@#\$%\^&\*\(\)\-\+=|\{\[\}'":\?><]/g);

(or escape just the -)
