title: how to enable a button in mvc razor based on radio button
body: <p>I have the following code:
  In Model: </p>
  
  <pre><code>&lt;div class="line"&gt;&lt;/div&gt;
  
  &lt;div class="clearfix"&gt;&lt;/div&gt;
          @Html.RadioButtonFor(x =&gt; x.Vehicle.Car, "Car")
          @Html.LabelFor(x =&gt; x.Vehicle.Car)
  &lt;div class="clearfix"&gt;&lt;/div&gt;
          @Html.RadioButtonFor(x =&gt; x.Vehicle.Van, "Van")
          @Html.LabelFor(x =&gt; x.Vehicle.Van)
  &lt;div class="line"&gt;&lt;/div&gt; 
  &lt;div class=".col-md-6 .col-sm-4  text-center"&gt;
          &lt;button type="button" class="btn btn-primary" disabled &gt;submit&lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I would like to enable the Submit button if either of the radio button is selected. Since using htmlhelper method, not sure of using Jquery method on it. Any help highly appreciated.</p>
