The only place where would actually be useful is wrapped around a tag in the head of the page to hide a CSS file from JavaScript enabled browsers but as you can only use noscript in the body it is an absolutely useless tag.įor example instead of using noscript to control which of two sentences appears like this: ĭocument.getElementById('script').innerHTML = "JavaScript is supported" That way yu have far better control and can even hide inline elements rather than just block elements.
JAVASCRIPT ALERT CODE
Just put the code in your page without the noscript tag and then use JavaScript to hide it when JavaScript is enabled. using noscript is more semantic way of catering for users that don’t have javascript, i guess.Īnd yes, I believe that in a thing such as a minimum requirements for visiting a webpage won’t go amiss… I also believe people should not use IE6 and be forced to upgrade, just as I believe in the tooth fairy… The reality is, you can do any of that on sites that don’t matter such as blogs, info sites etc - but you need to consider the potential paying customers on any business site… then, there are people that browse through lynx or their mobile browsers, etc etc.Īll i am saying is you should NOT design your site to function around javascript, javascript should be a way to compliment your site’s functionality instead.

for starters, there are plenty of people that browse with javascript disabled (almost 3% on one of my clients’ shop sites). This is way more flexible than since you can actually test for the browser supporting specific JavaScript commands using feature sensing and only hide the HTML when the features that your JavaScript requires to work are actually supported properly by the browser. All that is needed is to use JavaScript to hide anything in the page that you don’t want those with javaScript enabled to see. There is never a need to use tags with browsers more recent than IE4 and Netscape 4. You then try to hide the message with js.ĭocument.getElementById('js_disabled_message').style.display = 'none'

If you want to display a message to user with js disabled, to inform them they’re missing useful functionality without js, you just put the message into the html. You might be able to just add some enhancements to the existing html elements, or you may opt to simply replace large portions of the webpage with new stuff. Then, once that is done, you can add some javascript that will enhance the already working webpage. Make your webpage work properly as javascript did not exist. If someone does not have javascript enabled, how can I display a substitute html menu.ĭon’t think of of the regular html page as an alternative.

For those of us that are too new to javascript, could someone explain how I can either display a warning or provide an alternative when javascript is disabled on the browser?
