Hello,
Is there a way to add a regular expression validation in a multiple-line field?
Regards
Not sure if it's what you're looking for but these two threads may be of interest:
https://answers.laserfiche.com/questions/88571/multiline-number-input-validation
I got the answer from the first link itself. Here is the code i used:
$(document).ready(function () {
$('.numbers textarea').keyup(function() {
var invalidChars = /[^0-9\n\r]/gi
if (invalidChars.test($(this).val())) {
$(this).val($(this).val().replace(invalidChars,""));
}
});
});
Thank you Alex
Awesome, glad to see you got it working!
Thanks for sharing. I modified this to prevent the entry of characters which are not permitted in file names. Hope this saves someone so time:
