title: Which button toggle bootstrap modal
body: <p>I have bootstrap modal form, and several buttons, calling this form, like this:</p>
  
  <pre><code>&lt;a href="javascript:void(0)" data-toggle="modal" data-target="#specialoffer"&gt;
      &lt;button class="green full" id="button1"&gt;Ask Question&lt;/button&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>Can I send information, which button toggle modal form to modal form? I want to have something like this, in my form:</p>
  
  <pre><code>&lt;input type="hidden" name="caller" value="button1"&gt;
  </code></pre>
  
  <p>where "button1" is an id of the button, user pressed to activate the modal.</p>
