You can use bog standard HTML to do this - all 'modern' browsers support it:


<input type="text" ... ... maxlength="15" pattern="[a-zA-Z]{1,15}"

[download]

will only allow UPPER/lower case a to z up to a maximum length of 15 characters.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
