Make attachment mandatory when check box is selected

[Raghavendra]

Hi all,

I have one catalog item and it has one variable called "has_approval" and its type is "checkbox". If any user selects that checkbox, then the attachment should be mandatory. If the user selects the check box and if he didn't attach the attachment, then a pop up should show like "Please attach the attachment".

Can you please tell me how we should write the script.

Thank you

I would suggest adding a variable with the type of Attachment to your Catalog Item, then with a simple UI Policy you can make this variable mandatory when the checkbox value = true.  This is the simplest approach and works both in the native UI / Service Catalog and the Service Portal.  Here is an article detailing the other ways to make an attachment mandatory

Hi @Raghavendra ,

You can write an OnSubmit Client script and use below code

function onSubmit() {
var attachment = document.getElementById('header_attachment_list_label');
if (attachments.style.visibility == 'hidden' || attachments.style.display == 'none' ) {
alert('There is no attachment');
return false;
}
