title: jQuery form. Why to use it?
body: <p>I wanted to ask, why is it good or better to have a script print the form than plain html. And what's the difference? When I type: </p>
  
  <pre><code>&lt;form&gt;&lt;input type="button" value="button" /&gt;&lt;/form&gt;
  </code></pre>
  
  <p>or </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
       $form = $("&lt;form&gt;&lt;/form&gt;");
       $form.append('&lt;input type="button" value="button" /&gt;');
       $('body').append($form);
  &lt;/script&gt;
  </code></pre>
  
  <p>What if user disables javascript in his browser?</p>
  
  <p>For security, is the plain html and php enough or should I use javascript to build and validate the registration form?</p>
