title: Get the value of all the jquery inputs within a fieldset
body: <p>this is the first question i ask here. 
  I have a fieldset which has inside 4 inputs. I want to validate the form if at least 2 of 4 are completed. I can get the value of the first input with <code>$("#communications input").val()</code>.</p>
  
  <pre><code> &lt;fieldset class="input-group-fieldset bigger-labels" id="communications"&gt;
      &lt;div class="row"&gt;
          &lt;div class="columns twelve"&gt;
              &lt;div class="input-group" id="pref-mail-wrap"&gt;
                  &lt;label&gt;Email Address&lt;/label&gt;
                  @Html.TextBoxFor(model =&gt; model.PrefferedEmail, new { @class = "contact-group" })
  
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="row"&gt;
          &lt;div class="columns four"&gt;
              &lt;div class="input-group" id="pref-phone-wrap"&gt;
                  &lt;label&gt;Telephone No&lt;/label&gt;
                  @Html.TextBoxFor(model =&gt; model.PrefferedPhoneNo, new { @class = "contact-group" })
  
  
  
              &lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="columns four"&gt;
              &lt;div class="input-group" id="pref-sms-wrap"&gt;
                  &lt;label&gt;SMS No&lt;/label&gt;
                  @Html.TextBoxFor(model =&gt; model.PrefferedSmsNo, new { @class = "contact-group" })
  
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="" id="pref-address-wrap"&gt;
  
          &lt;div class="row fixed-width"&gt;
              &lt;div class="columns twelve"&gt;
                  &lt;div class="input-group2"&gt;
                      &lt;label&gt;Address &lt;/label&gt;
  
                      @Html.TextBoxFor(model =&gt; model.PostalAddress)
  
                  &lt;/div&gt;
              &lt;/div&gt;
  
          &lt;/div&gt;
  </code></pre>
  
  <p>Thank you in advance,
