  Here’s a way using the BrightSign unit webserver and user variables feature:

  1. Add variables in BrightAuthor

  2. In your JS use getUserVars (HTML attached). This will get the variable from the user variables on the unit.

  3. To put back to the unit use a from element (populate this in the background) and use ‘SetValues’ to post back to the database – i.e. “form id="main" action="/SetValues" method="post">. You could do this with a setInterval() to update the database as needed.
  

  Here’s some pseudo code for posting back to the database:

  function doUserVars(us) 
  {
    printObj(us)
  
    if(typeof us === 'undefined') 
    {
      console.log("userVars not defined"); 
        setTimeout(function(){getUserVars(doUserVars)},1000);
      return; 
    }
  
  var str='<form id="main" action="/SetValues" method="post">'; 
  $.each(us,function(){
    str+=this.key+':<br/><input class="bs_input" type="text" name="'+this.key+'" 
  value="'+this.value+'"/><br/>'; });
    str+='<br/><input id="button" type="hidden" value="Submit Cities"/></form>'; 
      $('div.varform').html(str);
  }
  
  function formsubmit(){
     $("#main").submit()
  }

  Thank you very much.
  Unfortunately that script does not work. I get Errors.

   

   

   

  <script>

  function getUserVars(callback){
   console.log("getUserVars");
   sUrl="http://localhost:8080/GetUserVars";

   $.get(sUrl,function(data,status,jqXHR){
    un=jqXHR.responseText;
    xmlDoc = $.parseXML( un );
    $xml = $( xmlDoc );
    console.log(un);
    console.log("fetching variables...")

   $xml.find('BrightSignVar').each(function(){
    var name = $(this).attr('name')
    console.log(name);
   
   switch (name) {
    case "volume":
     var volume = $(this).text(); break;

   $('#name').html(mmaker);

  </script>

  I never said it works :)

  What isn't working for you?

  If you shared the console.log() output at the various stages, we could try and help.

  I too cant get this working since upgrading from a series 3 to series 4 Player. Do you have a working presentation you could Share?

  Use of the Javascript console might be helpful.

  I'm no expert in Javascript, but I'm pretty sure the code above is incomplete.

  There are open braces, without matching closing braces, such as the switch statement.
