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

[Leo Cris Ramos]

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

In case you wonder where to create your own validation regex:

I do believe this should be your first go-to instead of Catalog Client Script.

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