Hello everyone!


I need a regex in javascript that can perform a validation of a company name.

I curently have " /^[A-Za-z0-9 ]{2,80}$/ ";

But this won't accept my country accents or spaces or special characters. Some examples of names that should accept:

-João Company
-Leão@
-édel Às
-4&you
-nº2

Also, it should check if it has at least 2 characters and not filled with whitespaces.

Basicly it allows any character but should not be filled with whitespaces only and should have at least 2 characters.

Thank you

How about this:

companyname.match(/\S.{0,78}\S/)

Open in new window


\S matches for everything expect whitespaces.

If you trim your companyname using this command before:
companyname = companyname.replace(/^\s+|\s+$/g,"");

thanks for the reply.

I am using the .test method, how can i store what u suggested   in a variable(var inNameReg)?

$('form').on('submit', function() {

	var info  = $('#infoSubmit');
	var inName = $('input#name-of-company');
	var inNif = $('input#nif');
	var inNameReg = /^[A-Za-z0-9 ]{2,80}$/;

        if ( !inNameReg.test(inName.val()) ) {  

        	info.text('please enter a valid name');
        	inName.addClass('wrongInput');
        	inName.focus();
        
        } else {
(...)

I never used regex.test(value), but it should work the same way you wrote.

var inNameReg = /\S.{0,78}\S/;

I can't say anything about inName.val() because it is part of a js-framework I don't know or use. I'd use:
inName.value.replace(/^\s+|\s+$/g, '');
if (!inName.value.match(/^\S.{0,78}\S$/) {
  alert('please enter a valid name');
}

Thanks, but what  {0,78} means? I see that I need to enter at least to characters and that's fine. But I also want to limit to 60 characters. I see the limit is not working in the current regex:

var inNameReg = /\S.{0,78}\S/;

This regex limits to 80 characters like your first one. The \S are two characters, adding the number in the brackets gives the maximum length.
If you want to limit to 60 characters the 78 must be a 58 (60-2).
To have this working, you need ^ and $ around your regex => /^\S.{0,58}\S$/. I missed those the first time, sorry.
