Format/Custom Keystroke Help

[okiiyama]

I would like to make sure the user doesn't type special characters into a certain field.

I found this:

if(!event.change.match(/\w+/g)){
	app.alert("Enter Letters or Numbers only.");
	event.rc = false;
}

but that messes up the whole page. Is there something similar I can use?

It may be easier to only permit specific characters then to exclude all special ones - I have a script which does exactly this. It is designed to stop special characters from being entered into a field who's value is used for a filename.

function FN_ks()
 {
FN_RegExp = /[A-Z a-z 0-9 _ . -]{0,60}/;
var value = AFMergeChange(event);
if(!value) return;
if (!AFExactMatch(FN_RegExp, value)) event.rc = false;
}
if (!event.willCommit) FN_ks();

This code specifies the exact range of characters to allow, and also restricts the number of characters allowed to a maximum of 60 (to prevent over-running 256 chracters in path). I initially had set out to do exactly what you are attempting, and received some help via this forum to get me to the script above, so I'm just passing on the knowledge.

Thanks, this should help.
