I want to flag a message if javascript is disabled at client side. I searched here and found <noscript> tag to use for handling this stuff.
I did this at w3schools editor to check but its not working let me know if this <noscript> is not meant for this or something else I am missing in this part ?

NoScript is, essentially, a Firefox add-on that disables things like JavaScript from running on web sites you visit.
To detect if JavaScript is disabled in a web browser, use the <noscript> tag. The HTML <noscript> tag is used to handle the browsers, which do recognize <script> tag but do not support scripting. This tag is used to display an alternate text message.
Definition and Usage The <noscript> tag defines an alternate content to be displayed to users that have disabled scripts in their browser or have a browser that doesn't support script.

When JavaScript is disabled, Just tried to redirect to some page where we can display the message that Javascript is disabled. There is meta tag in HTML named “meta refresh” which will redirect the user to another page in the interval specified in that header.
<noscript> <META HTTP-EQUIV="Refresh" CONTENT="0;URL=ShowErrorPage.html"> </noscript> As, we can see above code inside noscript, there is “meta refresh” tag with interval of “0″ second. As, the JavaScript is disabled in that page, the browser gets redirected to “ShowErrorPage.html” to show some warning message.
I hope this will help you.

You are right. The <noscript> tag is used to show only if JavaScript is disabled.
In order to test this, do the following:
As you can see, you can put any HTML inside the <noscript> tag that you would put inside the body of a page.
<html>
<body>
<h1>Simple Example Page</h1>
<script type="text/javascript">
document.write("Hi, JavaScript is enabled!");
</script>
<noscript>
<div style="border: 1px solid purple; padding: 10px">
<span style="color:red">JavaScript is not enabled!</span>
</div>
</noscript>
</body>
</html>
<noscript>
<META HTTP-EQUIV="Refresh" CONTENT="0;URL=ShowErrorPage.html">
</noscript>
is not a good solution as IE11 (and previous) have a security option that when set to 'high' disables both Javascript and Meta Refresh Tags!
The best solution I have found to handle this case is :
<noscript class="noscript">
<div id="div100">
Please enable javascript in your browser .... blah blah
</div>
</noscript>
<style>
body{
position:relative;
}
.noscript {
width:100%;
height:100%; /* will cover the text displayed when javascript is enabled*/
z-index:100000; /* higher than other z-index */
position:absolute;
}
.noscript #div100{
display:block;
height:100%;
background-color:white;
}
</style>
