I need to check if javascript is enabled or not on websites on every page. What is the best practice to consider apart from html element? How is it done using symfony2 specifically?

Thanks.

    This has nothing todo with Symfony2 or any php framework or any server side language.

    You just have to do it in your html layout.

    The best practice is to always set your page to have javascript disabled and then to enable it.

    It is commonly done by using this snippet.

    <html class="no-js" ="http://www.w3.org/1999/xhtml">
<head>
    <script type="text/javascript">
    //<![CDATA[
      (function(H){H.className=H.className.replace(/\bno-js\b/,'js');})(document.documentElement);
    //]]>
    </script>
</head>
<body></body>
</html>
