You can do the following:

Add a hidden textbox in your master page or your page as follows:

and call the function onload, if javascript is working the value in the texbox should change.

<body onload="CheckJsc()"> in your master page

function CheckJsc() {

document.getElementById("_ctl0_ContentPlaceHolder1_testBox").value = "yes";

}

</script>

then in the pages were u need to check if javascript is enabled (and these pages are using the master page where u have the hidden textbox)..

Check if the value in the textbox has changed if not redirect to the javascript.aspx page:

dim s as string = testbox.text or master.findcontrol("textBox").text

if (s="no")

' javascript is not working so

' response.redirect("...")

else

'continue ...

You can do something like this:

<div id="jsEnabled" style="visibility:hidden">
    JavaScript is enabled
    </div>

    <div id="jsDisabled">
    JavaScript is disabled
    </div>

Mmm, I guess the Javascript-enabled browser would initially see the warning message?

I wonder why the <noscript> option doesn’t work? This seems to be the most popular option.

I get a warning that it shouldn’t appear in the <head> section, but apparently this is an oversight and can safely be ignored?

Although I’ve never done this, I will have to in the near future so I’ve been watching the thread.

It seems to me that a good way to do this is to break the page into two panels <divs>, the first visible (‘display: block’ – the default) with a message saying ‘Javascript is disabled, please enable it’, and the second invisible (display: none;). On page load a Javascript function will hide the first panel and show the second.

document.getElementById("JsWarning").style.display = "none";
document.getElementById("theContent").style.display = "block";

If there’s no Javascript, the first panel will show. It will not redirect them of course, but the required content can be shown in the first <div> (one less trip to the server).

Will this work, or am I missing something?

Request.Browser.JavaScript only indicates whether the browser handles the JavaScript or not. You can turn off the JavaScript and it will still say "true". Here is a simple way to test if the JavaScript is enabled or not.

You print a message on the page saying "If you see the message below then the JavaScript is enabled". This means if the message is not displayed then the JavaScript is disabled.
