Make Labels mandatory on every Page

[Florian Wößner]

Is there a way to ensure a label must be entered before publishing or updating a page?

I tried including  a JavaScript in custom HTML:

<script type="text/javascript" src="/confluence/includes/js/label_alert.js"></script>

 At the moment the script looks like this:

<script type="text/javascript">
AJS.toInit(function(){
   AJS.$('#rte-button-publish').click(function(e){
      alert("Please add at least one or more labels");
   });
});
</script>

I have the code from this post: https://community.atlassian.com/t5/Confluence-questions/Mandatory-labels-in-Confluence/qaq-p/39597

Since it is the first time that I do something with custom html and javascript, I do not know if it is correct at all. In any case, I don't get any alerts.

I would be grateful for any help!
