Here is the code I used is a custom stage view I built to do this functionality in OBS.  I bolded the sections you will need to add to your javascript code to make work.  If you want the entire part I built I would be happy to share.  I am just displaying the text of the songs or the text of the scripture.  Plus a little footer with song title or scripture title.<br><br>

updateSlide: function() {

  if (OpenLP.currentTheme OpenLP.currentBlank)

  $("#currentslide").html("");

  else {

// Show the current slide if displayed

var slide = OpenLP.currentSlides[OpenLP.currentSlide];

var text = "";

text += slide["text"];

// Show the Song or Scripture Title

text += "<br /><div id='itemFooter'>" + OpenLP.itemFooter + "</div>";

text = text.replace(/\n/g, "<br />");

$("#currentslide").html(text);

text = "";

  }

  pollServer: function () {

    $.getJSON(

      "/api/poll",

      function (data, status) {

        if (OpenLP.currentItem != data.results.item ||

            OpenLP.currentService != data.results.service) {

          OpenLP.currentItem = data.results.item;

          OpenLP.currentService = data.results.service;

  OpenLP.currentTheme = data.results.theme;

  OpenLP.currentBlank = data.results.blank;

          OpenLP.loadSlides();

        }

        else if (OpenLP.currentSlide != data.results.slide) {

          OpenLP.currentSlide = parseInt(data.results.slide, 10);

          OpenLP.updateSlide();

        }

else if (OpenLP.currentTheme != data.results.theme  ||

OpenLP.currentBlank != data.results.blank) {

  OpenLP.currentTheme = data.results.theme;

  OpenLP.currentBlank = data.results.blank;

  OpenLP.updateSlide();

}

    );

  }
