I have list of radio button with true and false values. I want to get the value on change click event so I can use it for displaying conditional label. If its true; I'll show a label if its false different label. Its a list of items so I am looping through it..

here is what I have so far:

Model:

public List<bool>answerValues { get; set; }

View:

<td> 
   @Html.RadioButtonFor(model => model.answerValues[i], true, new { id = 
    "TrueValueID", @onclick = "buttonValue()"}) True

   @Html.RadioButtonFor(model=> model.answerValues[i], false, new { id = 
    "FalseValueID", @onclick ="buttonValue()" }) False 
</td>

JavaScript

<script src="//ajax.googleapis/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
 <script>
      function buttonValue(e) {
          alert(e.value);
      }

  </script>

In the Controller - Action method (Get), I want to get the true/ false value so I can show/hide based on values.

I am not familiar with Razor / MVC. any help will be highly appreciated!

You missed this, should use buttonValue(this):

<td> 
   @Html.RadioButtonFor(model => model.answerValues[i], true, new { id = 
    "TrueValueID", @onclick = "buttonValue(this)"}) True

   @Html.RadioButtonFor(model=> model.answerValues[i], false, new { id = 
    "FalseValueID", @onclick ="buttonValue(this)" }) False 
</td>

In action:

function buttonValue(e) {
  alert(e.value);

  if (e.value === 'true') {
    alert('it is true');
  } else {
    alert('it is false');
  }

}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="test" value="true" onclick="buttonValue(this)" />
<input type="radio" name="test" value="false" onclick="buttonValue(this)" />

I want to get the true/ false value so I can show/hide based on values

Radio button return on if checked, so show label if value return on else show another label. Also you can set value for radio button like <input type="radio" value="true"... or boolean.

I hope this will help you.

Razor Code

here we can set mon class on radio button to bind on change event in js.

<td> 
       @Html.RadioButtonFor(model => model.answerValues[i], true, new { id = 
        "TrueValueID", @class="rdbtnanswervalue"}) True

       @Html.RadioButtonFor(model=> model.answerValues[i], false, new { id = 
        "FalseValueID", @class="rdbtnanswervalue" }) False 
    </td>

Js Code

<script>
$(function () {
    $(".rdbtnanswervalue").on("change", function () {

        // for current value
        alert($(this).val());

        // for all radio button with same class unment below code.

        //$(".rdbtnanswervalue").each(index, ele)
        //{
        //    // get value and perfom action acordingly.
        //    alert($(ele).val())

        //}
    })
})

You should use name attribute for all radio buttons.

and then in JQuery

$('input:radio[name=RADIO_NAME]').change(function () {
        var value = $('input:radio[name=RADIO_NAME]:checked').val();
        switch(value).....

    });
