As per my knowledge you can't enable or disable JavaScript on a browser using code. If browsers allow a web page to play with it's settings, it would be very vulnerable.
Whenever you perform validations on a web page, the best practice is to do a client side as well as server side check.

Have look

<h1>noscript example</h1>
<noscript>
	<h3>JavaScript is disabled! Please enable JavaScript in your web browser!</h3>
 
	<style type="text/css">
		#main-content { display:none; }
	</style>
</noscript>
 
<div id="main-content">
	<h3>Browser already enabled JavaScript!</h3>
</div>
