    Why, please, this strange behavior?

    Why this script:



    --------------------------------------------------------------
    <div id='1'></div>
    <script language='javas cript'><!--

    function pippo(){
    alert('primo alert');
    var ddiv1 = document.getEle mentById('1');
    ddiv1.innerHTML = '1 elaborato con successo...<br> ';
    alert('secondo alert');
    }
    //--></script>
    <a href="#" onClick="pippo( );">Vai</a>
    --------------------------------------------------------------







    and this one NO?


    --------------------------------------------------------------
    <div id='1'></div>
    <script language='javas cript'><!--
    alert('primo alert');
    var ddiv1 = document.getEle mentById('1');
    ddiv1.innerHTML = '1 elaborato con successo...<br> ';
    alert('secondo alert');
    //--></script>
    --------------------------------------------------------------

    Tested on IE and FF, only first alert works in second case.

    I think because the page, in the second case, is not completely loaded.

    Isn't it?

    And if it is how can I do?

    Any help appreciated.

    Regards.

      I think that's right. How about using the onload event?

      <script type='text/javascript'>
      function doit(){
      alert('1st alert');
      var ddiv1 = document.getEle mentById('1');
      ddiv1.innerHTML = '1 elaborato con successo...<br> ';
      alert('2nd alert');
      }
      </script>
      </head>

      <body onload="doit()" ;>
      <div id='1'>
      </div>

          Minor points:

          1) The language attribute has been deprecated for over six years. Use the
          (required) type attribute instead.

          <script type="text/javascript">

          2) The practice of hiding scripts using SGML comments is also out-of-date.
          You can remove them.

          I would actually say, no. In my experience, as long as the element in
          question - a DIV here - has been parsed, you should be able to access it
          via a script.

          What could happen in your case is that because the DIV has no content, the
          browser is ignoring it. Try putting something - text, for example - in it
          and try again.

          If you're still having trouble, could you post a full example. I can't
          replicate the problem, so it might be something specific that you're doing.

          Replace ".invalid" with ".uk" to reply by e-mail.

              Good Job Michael :-)


              I post to you (and to the group) what did:

              I assume that you know some vbscript.

              <%

              for idx = 1 to 5
              response.Write( "<div id='" & idx & "' style='display: none;'>a</div>")
              next


              arrTest = array("a", "b", "c", "d", "e")

              cnt = 1

              response.Flush( )

              for idx = lbound(arrTest) to ubound(arrTest)

              response.Flush( )
              response.Write( vbcrlf)
              response.Write( "<script language='javas cript'><!--")
              response.Write( vbcrlf)
              response.Write( vbcrlf)
              response.Write( " var ddiv" & cnt & " = document.getEle mentById('" &
              cnt & "');")
              response.Write( vbcrlf)
              response.Write( " ddiv" & cnt & ".innerHTML = '" & cnt & "
              succesfully elaborated...<b r>';")
              response.Write( vbcrlf)
              response.Write( " ddiv" & cnt & ".style.dis play = '';")
              response.Write( vbcrlf)
              response.Write( vbcrlf)
              response.Write( "//--></script>")
              response.Flush( )


              ' Here I try to give some delay to sequentially let the DIVs to be drawed

              for ix = 1 to 100000
              response.Flush( )
              next

              cnt = cnt + 1

              response.Flush( )

              next
              %>



              It works.

              Regards.
