Visualize.js and dashboard data

[Roman2024]

Hello everybody.

I'm trying to get data from Jasper dashboard before it renders in window. I'm using a script with visualize.js in HTLM page. I would like to get "beforeRender" event, but I don't know how to do it. Should I use this event or something else for getting data? How should I configure Jasper dashboard for getting this event?

 

 v("#container").dashboard({

          server: "https://localhost:8443/jasperserver-pro",    

          resource: "/public/TestDashboard",

          params: initialParams,

          linkOptions: {

            beforeRender: function (linkToElemPairs) {

              console.log('linkToElemPairs: ', linkToElemPairs);

              linkToElemPairs.forEach(showCursor);

            },

           error: function(e) { 
                alert(e); 
            } 
        });
