Getting text area and checkboxes to display with radio buttons

Question

As displayed below I am working on a survey, I've spent most of the night getting the radio buttons to work and I have now ran into a new issue. How do I go about getting the text fields and checkboxes to display in addition to the radio buttons when the user clicks submit.

Currently, only question 2 responses are recorded and displayed. Thank You

Answer 1

You do not need to use a custom loop to retrieve the selected combos or checkboxes. If I may have a suggestion, you may use querySelector and querySelectorAll that are designed for this.

Also you may want to use form.addEventListener("submit", callback); instead of form.onsubmit so that you can add more than one listener for the submission of a form and that you do not have to hack into your button's onclick event.

Here is a working example:

// Avoid polluting global namespace.
(function() {
    // Helpers
    function forEach(list, callback){ return Array.prototype.forEach.call(list, callback); };
    function map(list, callback){ return Array.prototype.map.call(list, callback); };
  
    var survey = document.forms['mySurveyID'];
    // Listen for submit events (need a "submit" input instead of
    // "button", cf HTML).
    survey.addEventListener("submit", function(eat){
      // Retrieve question 1's checked inputs.
      var q1CheckedInputs = survey.querySelectorAll("input[name=Q3]:checked");
      // Extract inputs' values.
      var q1Answers = map(q1CheckedInputs, function(inputNode){
        return inputNode.value;
      });

      // Retrieve question 2's answer.
      var q2Answer = survey.querySelector("input[name=ques5]:checked").value;

      // Retrieve question 3's answer
      var q3Answer = survey.querySelector("textarea[name=Q2]").value;

      // Show results.
      alert('Q1: "' + q1Answers.join('", "') + '\n' +
            'Q2: "' + q2Answer + '\n' +
            'Q3: "' + q3Answer + '"');
    });
    
    // Disable submission of all forms on this page.
    forEach(document.forms, function(form){
      form.addEventListener("submit", function(evt){
        evt.preventDefault();
      });
    });
    
}());
