Question 196848 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – RegEx help for special characters and spaces

I need the following:

  • No numbers
  • Only allow the special characters - and '
  • Spaces should not be allowed at the beginning or end of the field
  • Remove any additional blank space if found between parts of names (allow only one space between parts of name – if multiple middle names)
  • Allow diacritics

Chat GPT gave the following:

^(?!.*d)[p{L}'-]+$

However this still allows me to enter consecutive spaces.

    OK, found the answer:

    ^(?!.*d)[p{L}'-]+(?:s[p{L}'-]+)*$

    I think you could do something like that in JavaScript:

    const myString = "Hello    world!  This   is pizza?";

const regex = /^(?!.*d)[p{L}'-]+$/g;
const result = myString.replace(regex).replace(/s+/g, ' ');

console.log(result);
