Question

I am trying to validate an input string (which can be copied & pasted in the textbox).
The input entered should contain one or more alphabetic characters, numbers and two more special characters as (& and Ñ), but no embedded spaces.

NB: Alphabetic characters must present, but numbers & those two special characters may or may not present to create a valid input.

I am using Jquery for client side validation.

• Alternative Approach:

  If anyone can help me how we can detect the occurrence of any special characters and spaces, except ‘&’ and ‘Ñ’ in any input string, then also my problem can be resolved.

Answer 1

Actually I am done with the validation with Jquery alphanumeric plugin

i.e "$('#txtId').alphanumeric({ allow: "&Ñ" });".

Explanation: This allows all alpha numeric characters & restricts all other characters (special characters got addressed). In the allow part I could place the allowable special characters.
