Answer 1

You can use the noscript tags to display content to browsers with javascript disabled or redirect them to another page (a nojs-version.php for example).

Modernizr

The better way to handle javascript detection (& feature) would be to use Modernizr: http://modernizr.com

Check out this SO question: What is the purpose of the HTML "no-js" class?

A basic example (without Modernizr)

You could add the class no-js on page load to your tag. Then when the page loads and if javascript is enabled, you can replace the no-js with js like so:

// When the DOM is ready & loaded, do this..
$(document).ready(function(){
    // Remove the `no-js` and add the `js` (because JS is enabled (we're using it!)
    $('body').removeClass('no-js').addClass('js');

    // Assign it to a var so you don't traverse the DOM unnecessarily.
    var useJS = $('body').hasClass('js');
    if(useJS){
        // JS Enabled
    }
});

The above code is a very basic example of how modernizr works. I would highly recommend just using that.
