How do I require JavaScript (Active Scripting)?

[Prometheus]

I need to have a form plug into javascript and if the user does not have active scripting enabled, I want it to tell them to turn on active scripting.

How do I do this? Anyone know the code?

Since page content can only be changed using Javascript, you should have the default page content show the error message indicating that Javascript is required. For example:

<div id="jscheck">
   <p>This function requires JavaScript. You're browser does not support the Javascript functions
   used to implement this function, or JavaScript is not enabled. Please enable JavaScript on
   your browser and refresh the page.</p>
</div>

And then create a script that will replace the error message if JavaScript is enabled on the visitor's browser.

<script>
if (document.getElementById) {
   formarea = document.getElementById("jscheck");
   formarea.innerHTML = '<p>You have JavaScript enabled! Yay!</p>';
}
</script>

Or just use the <noscript> option, thus:

    <div id="warning"><script type="text/javascript">
    <!--
    // -->
</script>
<noscript>
<p>Your browser doesn't support JavaScript or JavaScript support has been disabled. You must enable JavaScript to use this application.</p></noscript>
</div>

Ok, good ideas. I think I can work with them. My issue is that I want to show most of the page regardless of JavsScript or not. If they want to submit contact information, I want them to know that they must have JS enabled as I run an inline form validator when submit is hit. I guess I can take the whole form and stick it inside the jscheck innerHTML area. I'll give it a shot.

A bit of background ... my issue overall is a contact form that has required fields with a JavaScript validator.

When people submit without JavaScript, they can put whatever they want or leave fields blank. We're about to do a database move and I need to make certain that the data is complete when moving over. So if I can let them see the form, but not let them submit it w/o JavaScript then that's my goal.

You should always check submitted data serverside regardless of whether or not you validate it browser side using JS.

So is the true solution to find an ASP form validator?

I'm not an ASP scripter but I do believe that ASP has form validation functions built in. In PHP you would have to write your own but that is simple enough.
