How to set number range in Single-line text variable type in service catalog?

Leo Cris Ramos · ‎08-17-2021

Hi, Everyone.

I used single line text variable and changed the validation regex to Number.

However, I'm not sure how to set a number range, for example the maximum person can be in a room is only 25.

Can someone help?

Hi Leo,

This has no limit on the number of digits.

If you want to restrict or set the range you will have to use a OnChange Client Script:-

The logic you should use is below:

function onChange(control, oldValue, newValue, isLoading) {

if (isLoading || newValue == '') {

return }

var regExTest = /^[1-9][0-9,]*$/;

if(!regExTest.test(newValue)){

alert("Please enter valid characters"); g_form.setValue('urfieldname', '');

} }

Please mark my answer as Correct & Helpful, if applicable.

Thanks

Hi.

How about changing the variable type to Numeric scale instead?

Otherwise you need to perform some additional logic (onchange script) to validate that the number entered is max 25.

I need to set it from 1-999 🙂

Then I would go with @Mark Roethof solution, create a custom variable regex.

To try and learn about regex, you can try this page: https://regexr.com/

Hi there,

So your question is a Regex for 0 to 25? Or is your question different?

If 0 - 25:

\b([0-9]|1[0-9]|2[0-5])\b

If my answer helped you in any way, please then mark it as helpful.
