title: send input value via ajax without using val() function
body: <p>my use-case is this : 
  I have several <code>input</code> : </p>
  
  <pre><code>  &lt;label class="minilabel"&gt;Field1&lt;/label&gt;&lt;input type="text"&gt;
    ...
    &lt;label class="minilabel"&gt;FieldN &lt;/label&gt;&lt;input type="text"&gt;
  </code></pre>
  
  <p>I have to get the <code>value</code> of each <code>input</code> and then send it via <code>AJAX</code> (a <code>post</code> request). 
  Usually I set an <code>ID</code> to each <code>input</code> then I retrieve it through <code>$("#id1").val()</code> .. <code>$("#idN").val()</code> , but it such intricate. There is an alternative way to get these values?</p>
