don't show null attribute values in featureLayer popup with javascript api

MikeBell

Hi,

I'm just creating a simple map to display one point dataset. When the user clicks on a point I want a popup to display, some of the attribute fields contain null values and ideally I don't want these fields to be included in the popup if the value of the attribute is null. I've tried to find the answer to this question and have come across a solution when using data coming from a queryTaskLayer but I'm looking to do this on a featureLayer. Any suggestions on how to do this with a featureLayer?

Cheers,

Mike

You need to create a function and set it as your infoContent.  I'm not using a popupTemplate, I'm using an infoTemplate, but it should be the same concept.

  var infoTemplate = new InfoTemplate();

  infoTemplate.setContent(generateInfoContent);

//creates string for info tag

  function generateInfoContent(graphic){

    var formatString = "";  

    var disclaimerTest = graphic.attributes.HOURS_OF_OPERATION_DISCLAIMER;

    var adaTest = graphic.attributes.ADA_ACCESS;

    var idTest = graphic.attributes.ID_REQUIRED;

//these fields always have data, so start with a string that contains them and then append the others only when they have values.

    formatString = "<b>"+graphic.attributes.FACILITY +"</b><br/>" +graphic.attributes.ADDRESS+"<br/>"

    + graphic.attributes.CITY+", " + graphic.attributes.STATE + "</br>"

    + "Phone: " + graphic.attributes.PHONE + "<br/>"

    + "Hours: " + graphic.attributes.HOURS_OF_OPERATION;

   if (disclaimerTest){

     formatString += "<br/>" + graphic.attributes.HOURS_OF_OPERATION_DISCLAIMER;

   }

  if (idTest && idTest !== 'UNK' ) {

    formatString += "<br/> ID Required?:  " + graphic.attributes.ID_REQUIRED;

  }

  if (adaTest && adaTest !== 'UNK' ) {

    formatString += "<br/>ADA access?:  " + graphic.attributes.ADA_ACCESS

  }

    

    return formatString; 

  }
