      Yes. Try executing some JS in your web page. If it runs, JS is
      enabled. If it doesn't, it isn't.

          Here's one way. Watch for word-wrap.

          <html>
          <head>
          <title>jsenable d.htm</title>
          <script type="text/javascript">
          function js() {
          document.getEle mentById("JS"). innerHTML = "JavaScript is enabled!"
          }
          </script>
          </head>
          <body onload="js()">
          <span id="JS">JavaScr ipt is not enabled!</span>
          </body>
          </html>

          I doubt that it's cross-browser compatible -- we'll probably hear from
          others!

                  = "Javascript is enabled, your browser supports getElementById and it
                  supports innerHTML. Doesn't mean a lot though."

                      You should first ask yourself how the information might be used; or, if
                      you know, explain your intent.

                      ISTM perfectly possible (untested) to do something like

                      <script type="text/VBScript"> dim JSisON : JSisON=false </script>

                      <script type="text/javascript"> JSisON=true </script>

                      <script type="text/VBScript">
                      document.write " JS is ON is ", JSisON </script>

                      but rather unusual.

                      Otherwise, what you ask is not entirely unlike asking what the result of
                      your own last round of Russian Roulette was.



                      One possibility is to put on the first page, presumably at the top,

                      <script type="text/javascript"> location.href = "XX.htm" </script>

                      Page XX.htm will be reached when javascript is enabled; otherwise, the
                      first page remains scriptlessly active.
