    How display dynamic text string?

    I would like to have a errorMessage displayed in a webpage. When a
    function is called the text changes. My code below replaces the html
    page with the errorMessage instead of embedding it into the html code.
    Its a stripped down version of the actual code but contains the same 3
    pieces: An action to validate a form, the function to check if the
    form is valid, and a function to display the type of error. Any
    suggestions? -Nick


    <html>
    <head>
    <script language="JavaS cript" type="text/JavaScript">

    function isError(error) {
    if (error == 'yes') displayError("T here has been an error");
    }

    </script>
    </head>
    <body>
    <script language="JavaS cript" type="text/JavaScript">

    function displayError(er rorMessage) {
    document.write( errorMessage);
    }

    </script>
    <a href="#" onClick="isErro r('yes')">Displ ay Error</a>
    </body>
    </html>

      Yeah... do something like this:

      <SPAN id=errorMessage Text></SPAN>

      Then, in a script, you can do this:

      <SCRIPT type="text/javascript">
      function displayError(er rorMessage) {
      document.getEle mentById("error MessageText").i nnerText = errorMessage;
      }
      </SCRIPT>

      If you want more formatting than plain text, use innerHTML instead of
      innerText

              However, it is important to note that innerText isn't supported by the
              Mozilla family of browsers (amongst others, no doubt). innerHTML is better
              supported.
