HTML feature test using pure JS.

featureTest.js

function featureTest() {
  document.getElementById("heading").innerHTML = "Compatible HTML5 Features";
  var typeValues = ["search", "number", "range", "color", "tel", "url", "email", "date", "month", "week", "datetime", "datetime-local"];
  var i = document.createElement("input");
  var dataValues = "";
  dataValues += "<ul>";
  for(l=0; l <= typeValues.length; l++) {
                i.setAttribute("type",typeValues[l]);
                var result = i.type !== "text" ? "YES" : "NO";
                dataValues += "<li>" + typeValues[l] + ": " + result+"</li>";
      }
      dataValues +="</ul>";
      document.getElementById("output").innerHTML = dataValues;
}

For this method, it orders the results in a list, however, you can remove that and just test for the conditionals.
