Pebble App SendGet.js

JavaScript
This is the Pebble Javascript file that sent the get request which triggered the IFTTT event to execute the file on the Intel Edison
var xhrRequest = function (url, type, callback) {
  var xhr = new XMLHttpRequest();
  xhr.onload = function () {
    callback(this.responseText);
  };
  xhr.open(type, url);
  xhr.send();
};

function getRequest(pos, toggle) {
  // Construct URL
  var url = 'https://maker.ifttt.com/trigger/ToggleLED/with/key/dWqDNCPc3fXu3etvPwobbs?value1=' + (pos+1);

  xhrRequest(url, 'GET', 
    function(responseText) {
    });
}

Pebble.addEventListener('appmessage',
  function(e) {
    getRequest(e.payload.position);
  }
);
