    JAVASCRIPT recusive function

    Any ideas why this function is not working.
    I am running it locally on my private network.


    <!doctype html public "-//w3c//dtd html 4.0 transitional//en">
    <html>
    <head>
    <title>Javascri pt Webcam for Internet Explorer</title>
    <meta http-equiv="Content-Type" content="text/html;
    charset=iso-8859-1">

    <script LANGUAGE="JavaS cript">
    <!-- hide from old browsers
    var chgcntr=1;

    currentdate = new Date();
    currenttime = currentdate.get Time();


    function changeit() {
    if (chgcntr > 0) {
    var imgsingle = "http://192.168.0.1/webcam/webcam.jpeg";

    document.imgroo m.src = imgsingle;
    setTimeout("cha ngeit()",3000);
    }
    }
    //end hide -->
    </script>

    </head>
    <body text="#000066" bgcolor="#FFFFF F" link="#0066FF" vlink="#00AAFF"
    alink="#FF0000" onload="changei t()">

    <center>
    <IMG src="" name="imgroom" alt="Picture" height=240 width=320></img>


    </center>
    </body>
    </html>


    Thanks

      If you go to this url in your browser do you see an image at
      http://192.168.0.1/webcam/webcam.jpeg?

          Hi,
          I guess it's on his private network and not viewable to us.

          For test purposes I modified the code slightly to see what I could see.
          With the modified changeit() below and 2 images in the same directory as my
          html,
          I see the alt "text" incrementing and the pictures swapping every 3 seconds.

          As noted in other posts, it is always helpful to provide
          a more detailed description than "not working".

          function changeit() {
          if (chgcntr++ > 0) {
          var imgsingle0 = "catnglasses.jp g";
          var imgsingle1 = "catnfood.j pg";

          if (chgcntr % 2 == 0) document.imgroo m.src = imgsingle0;
          else document.imgroo m.src = imgsingle1;

          document.imgroo m.alt=chgcntr;
          setTimeout("cha ngeit()",3000);
          }
          }

              Hi Chris,

              That's what I thought too (image is only accessible on his local
              network), but I though I'd better ask him to make sure the image really
              exists at that location, is spelled right, etc.... the code looks okay
              to me (I'm no expert though).

              Mike

                  Thanks for your help, but unfortunetaly even you code did not work.

                  I erased the htm file and I created a new one and it helped.

                  Thank You

                      Okay, what was it that made it work?
