    Back with validation through javascript......

    Hey.... The validation system that kaeli made works smooth.... Now I was
    wondering if it would be correct to make some variations to it like this:


    -----original kaeli's code-------

    <html>
    <head>
    <title> test </title>
    <script type="text/javascript">
    function checkLogin()
    {
    var a=prompt("enter the password");
    if (a=="noway") writeSuccess();
    else writeFail();
    }
    function writeSuccess()
    {
    document.getEle mentById("write Area").innerHTM L="Success!";
    }
    function writeFail()
    {
    document.getEle mentById("write Area").innerHTM L="Fail!";
    }
    </script>
    </head>

    <body onLoad="checkLo gin()">
    <div id="writeArea"> </div>
    </body>
    </html>


    -------my variations--------

    <html>
    <head>
    <title> test </title>
    <script type="text/javascript">
    function checkLogin()
    {
    myhtml = "thewholelo t of my web page from after <body> and until before
    </body>
    var a=prompt("enter the password");
    if (a=="noway") writeSuccess();
    else writeFail();
    }
    function writeSuccess()
    {
    document.getEle mentById("write Area").innerHTM L= myhtml;
    }
    function writeFail()
    {
    document.getEle mentById("write Area").innerHTM L="Wrong password!!! Reload
    the page";
    }
    </script>
    </head>

    <body onLoad="checkLo gin()">
    <div id="writeArea"> </div>
    </body>
    </html>


    So, you think it's correct? Should I have any kind of consideration since I
    am trying to create a character-like variable that is 16kb wide??

    Cheers!!!

      You missed a couple things.

      Forgot end quotes. VERY important. Also a semi-colon is standard.
      var myhtml = "thewholelo t of my web page from after <body> and until
      before</body>";

      Now, you made this variable that is only good in this function. How is
      the other function going to see it?
      That's called SCOPE.
      Either pass the variable to the other functions or make it global by
      putting
      var myhtml;
      before and outside of any functions. (do not redeclare with var in front
      inside a function if you do that)

      > var a=prompt("enter the password");
      > if (a=="noway") writeSuccess();[/color]

      So, if you passed the string, it would be
      writeSuccess(my html);
      [color=blue]
      > else writeFail();
      > }
      > function writeSuccess()
      > {
      > document.getEle mentById("write Area").innerHTM L= myhtml;[/color]

      myhtml is not defined in this function.
      If it were passed, it would be, or if it were global, but it is neither.

      The rest looks good. :)

      You are creating a string (not 'character-like'), which as far as I
      know, all variables declared with "var" in javascript are actually
      variants and quite large enough to hold only 16kb.
      I've put a lot more than that in a string when I had to support NN4. *G*

          You have to be careful with your quotation and quote marks!
