Regular expression javascript - validate name of company with accents/others

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/;
