How do i get the amount of labels of current page with JavaScript?

Florian Wößner

Hello,

I am looking for a way to get the number of labels from the current page that I have open in the editor.

This script runs when the editor is loaded:

// load editor first
AJS.bind("init.rte", function(){
      var buttonID = "rte-button-publish";
      //check if publish button exist
      if(AJS.$("#" + buttonID).length > 0) {
          //onClick
          AJS.$("#" + buttonID).click(function (e) { 
                console.log("Clicked 'Publish' page button", this);
                var labelbutton = "rte-button-labels";
                // HOW DO I GET THE LABEL COUNT
                if(AJS.$("#" + labelbutton).find(".trigger-text").text() == "Labels")
               {
                      //show alert
                      alert("Please add at least one or more labels!");
                      console.log("Show Alert", this);
                      //Dont finish Action
                      e.preventDefault();
                      console.log("Default prevented", this);
                      e.stopPropagation();
                      console.log("Stoped Propagation", this);
                }

           });
       }
});  

Basically only the last the if statement in the code above doesn't work for me.

I need something like:

if (LABELCOUNT == 0) {DO THIS;}

 

I am thankful for every help!

Hey friend!

If you're trying to get the labels for a page, it may be easier for you to just make an AJAX call to the confluence REST API. Specifically, there's an API for labels, that will give you the label data for whatever page you specify. 

Here's a quick and dirty example of how this could work:

let pageId = (new URL(document.location)).searchParams.get("pageId")

AJS.$.ajax({
    url: AJS.contextPath() + "/rest/api/content/" + pageId + "/label", 
    success: function(result){
      console.log(result.size); //result.size is the number of labels
}});

Obviously you'd want to add all of your logic around that and clean it up, but I believe that will get you what you need.

Let me know if you have any questions or if you'd like me to clarify anything further!

Best,
Aidan
