Hello all
I have been searching for about an hour for a functions that will not allow numbers in a text fields and have no luck.
There are lots of code out there written for 'numeric only' fields but does anyone have a sample of a fields that only allows TEXT?
Please post the full code (form, script, etc.)

You'll find it here -

Although I gues you'd have to tweak it a bit to adapt to what you require.

the important part is the regular expression:
/\d/
If you put this into string.match, it will return the number of numbers in the text, so:
"abcdefg".match(/\d/) == 0
"abc2defg".match(/\d/) == 1
"ab3cde4fg".match(/\d/) == 2
So you can test input.value.match(/\d/) for being greater than 0 to tell if there are numbers or not.

this is the bit that does the filter
.replace(/\d/g,'');
means
if any character is a digit replace it with ''
\d = any digit
g = any character in the string

Guys I am a newbie which is why I am asking questions on the list.
posting pieces of code is still like a foreign language to me.
Can you send me the script and form field syntax?
