    onerror - help required

    [HTML]<html>
    <head>
    <script type="text/javascript">

    onerror=handleE rr;
    var txt="";

    function handleErr(msg,u rl,l)
    {
    txt="There was an error on this page.\n\n";
    txt+="Error: " + msg + "\n";
    txt+="URL: " + url + "\n";
    txt+="Line: " + l + "\n\n";
    txt+="Click OK to continue.\n\n";
    alert(txt);
    return false;
    }
    function message()
    {
    adddlert("Welco me guest!");
    }
    </script>
    </head>

    <body>
    <input type="button" value="View message" onclick="messag e()" />
    </body>[/HTML]

    This code returns
    "object expected" in IE and
    "adddlert not defined" in Mozilla Firefox

    Question:

    I want the data "adddlert not defined" to be displayed in IE too. How can i get that information in IE ?

      hi ...

      welcome to TSDN ...

      i think you cannot control what error-message the js-runtime throws ... so without checking and replacing it explicitly i'm quite sure that there is no possibility to control the msg.

      kind regards

          Do you have any suggestion to explicitly track the information?
          Can't java runtime throw same error message in mozilla and IE?

          Any help on this will be appriciated ..
          thanks Gits for your kind reply ;-)

              hmmm ... you would have to use a try-catch statement and catch and handle any error for yourself ... its quite a task :) if you have that requirement i think there is no chance to do it another way ... otherwise i think it's quite useless ... because you could simply use the messages of the js-runtime where IE gives you the bad ones ;) ...

              kind regards

                  Hi Gits,

                  My intention is to try and find the javascript error that happens and log the same.
                  The error happens very rarely , so i would want the error to be logged whenever it happend so that i can find and solve it.
                  Since i dont exactly know where the error causng code is, I cant jus try catch :(

                  So any information on logging the js errors is also welcome

                  thanks again

                  anand

                      as i said ... you are then bound to that what the runtime gives you ... and have to live with IE's often useless messages and wrong line-numbers ...

                      kind regards
