How to Format text field to alpha only

[rservais]

Anyone have insight on the custom format script for creating text fields with alpha only input?

You can use this code as the custom Keystroke script:

if (event.change) event.rc = /^[a-z]+$/i.test(event.change);

I have a field - Case Name, and I used the coding above - if (event.change) event.rc = /^[a-z]+$/i.test(event.change); - and yes I can only type alpha characters in it, which is great but I cannot put a space between the first and last name.

Example: Jane Doe becomes JaneDoe

Is there a way to allow spaces?

Thank you,

Simply add a space character inside the square brackets.

However, names can contain all kinds of characters, beside letters and spaces. What about hyphens? Apostrophes? Periods?

Do not forget capitol letters.

[try67]

Capital letters are already allowed by the script above, because of the "i" flag.

[Angus24]

Hmm, I didn't think of those scenarios.

Can you direct me to maybe a pdf document or some source where I could find coding for spaces, hyphens and such.

Thanks!

Basically, you should insert all the characters you want to allow into the square brackets.

Got it, but how do I find out what represents the characters like for a space?  Can you direct me to where I can go to look these items up?

Where I can find out what the coding that you provided is actually doing and what the symbols mean (bolded text below)?

if (event.change) event.rc = /^[a-z]+$/i.test(event.change);

See Special characters meaning in regular expressions

Then scroll down to "Character Classes"

\s  Matches a single white space character, including space, tab, form feed, line feed and other Unicode spaces. Equivalent to [ \f\n\r\t\v\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff].

\t	Matches a horizontal tab.
\r	Matches a carriage return.
\n	Matches a linefeed.
\v	Matches a vertical tab.
\f	Matches a form-feed.
[\b]	Matches a backspace. (Not to be confused with \b)
\0	Matches a NUL character. Do not follow this with another digit.
\cX	Where X is a letter from A - Z. Matches a control character in a string.

if (event.change) event.rc = /^[a-zA-Z\s]+$/.test(event.change);
