regex in client script

Prem13 · ‎06-02-2020

i tried with the below regex

var regexp = /\d{6}@\d{5}/;
var idi = id.match(regexp);

in this before "@" i should be able to enter 6 characters and after "@" it should contain alpha numeric characters which should be 5 characters in length

Hi,

I'm not sure what you mean by "where I can enter more than 6 characters before '@' and 5 characters after '@'".

So, yes, you can, but your validation in your client script would then check that against the pattern you've defined and if it doesn't match/work with it...you would clear the field and maybe give an alert to say "please enter in 'x' format".

The regex doesn't literally block someone from entering in a bunch of characters...it's the validation in the client script that would check it.

For example, go to: https://regex101.com/

And in the regular expression field at the top of the website, put: \d{6}@[a-zA-Z0-9]{5}

Then do some test strings for yourself. You'll see on the right, in the Match Information section...they aren't matches UNTIL you do 6 numbers, then a '@' and then 5 characters of letters or numbers.

So for this to then work in SN, you have to add / to front and / to back of the pattern. So it now becomes:

/\d{6}@[a-zA-Z0-9]{5}/

And then that should work.

But again, users can enter in all sorts of stuff in that field...it's the onChange client script that would check what they enter, against a pattern, and if it doesn't match....you'd clear the value and alert them to the pattern you're expecting.

Hey Prem ,

i think you are trying to validate the email here with regex but you can use below script,

if(oldValue != newValue){

g_form.hideFieldMsg('email', true);

if (!isEmailValid(newValue)) {

g_form.showFieldMsg('email', newValue + " is an invalid email, please re-enter email in correct format.",'error');

} }

Or

hi allen,

I need to type only 6 characters before @ and 5 characters after @

is it possible to restrict character limit

Before "@" 6

After "@" 5

Since in both before and after i can enter n number of numbers
