    Selecting a Text Field on Page Refresh

    I have the following simple page. I need to select the BARCODE text field everytime the page refreshes. I know this is pretty basic, but I'm just starting with Javascript. Thanks for the help.

    [HTML]<head>

    <meta content="http://schemas.microso ft.com/intellisense/ie5" name="vs_target Schema">
    <LINK href="css/radevice.css" type="text/css" rel="stylesheet ">
    <script language="JavaS cript" src="/scripts/URLhandle.js" type="text/javascript"></script>
    <script language="javas cript" src="/scripts/refresh.js" type="text/javascript"></script>
    <script language="javas cript">
    </script>
    <SCRIPT LANGUAGE="JScri pt">
    </SCRIPT>

    <meta http-equiv="Refresh" content="10"

    </head>

    <body lang=EN-US style='tab-interval:.5in'>

    <div class=Section1>

    <h1 align=center

    Line:3

    </h1>




    <table>


    <td align=center><F ONT SIZE="4">
    Line:3
    </td></tr>

    <td align=center><F ONT SIZE="4">
    <form action="/rokform/WriteLogixTags" method="GET">
    Pick Status:
    <input type="hidden" name="redirect" value="/user/Web/HH.asp">

    <input type="hidden" name="t_1_tagna me" value="RB3Board Feedback">

    <input type="input" name="t_1_value " value="<%ReadLo gixTag("1,0","R B3BoardFeedback ","STRING");%>" >

    </form>
    </td></tr>



    [B]<td align=center width="50%"><FO NT SIZE="4">

    <form action="/rokform/WriteLogixTags" method="POST">

    <input type="submit" name="submit" value="Set Value">
    </form>
    </td>
    </table>


    </div>

    <p class=MsoNormal ><o:p>&nbsp;</o:p></p>

      just insert:
      Code:
      <BODY onLoad='document.getElementById("t_1_value").focus();'>
      One tip from a long-time expert: don't use generators for your page, just learn HTML and do it manually!
      Garbage like
      Code:
      <p class=MsoNormal><o:p>&nbsp;</o:p></p>
      is an indicator that you used Microsoft Word or another microsoft-office-product to make this page!
      They are doing nothing except slowing down your page and making modifications very difficult!

          That wouldn't quite work because the ID hasn't been set. If the id of the text field is set to "t_1_value" , it should work as expected.

          Agree with your tip :)

              But what you said is wrong for IE, I tested it.

              example code, test it yourself.:
              Code:
              <input type=text name="myBox">
<input type=text onChange="alert('You entered above: ' + document.getElementById('myBox').value)"'>
              It seems that if an element does not have an "id", but a "name", then
              getElementById( ) fetches the element as though the name would be its id.

                  Yes, I know that "works", but it's wrong and buggy. document.getEle mentById() should only fetch an element by its ID as its name suggests, not the element's name. This won't work in any of the other browsers.

                  To fetch an element by its name, we have document.getEle mentsByName().
