How to code a free text field data to then be captured

A: In your code add the following. ("hospitalName" here is used as an example).

In the slide HTML file (e.g. slides/demo_slide.html):

<input type='text' id=“hospitalName”>

In the slide JavaScript file (e.g. code/js/demo_slide.js):

var slide = app.slide.demo_slide = {
 onEnter: function(ele) {
  slide.hospitalInput = ele.querySelector('#hospitalName');
  app.addEvent('blur', this.monitorHospital, slide.hospitalInput);
 },
 monitorHospital: function(e) {
  var hospital = slide.hospitalInput.value;
  if (hospital) {
   ag.submit.data({
    category: 'User input',
    label: 'Hospital',
    value: hospital
   });
  }
 }
};
