    problem with getElementsByName

    Hi, I cannot figure out why everything from line

    var elem = doc.getElements ByName('keyword s')

    in x.js is not executed. My goal is to set value of <input
    name=keywords ...which is in a.html after page is loaded.

    ------------------ search.html --------------------

    <html>
    <head>
    <title>Search </title>
    <script src="x.js"/>
    </head>

    <frameset rows="*" onload="load()" >
    <frame src="search-1.html"/>
    </frameset>

    </html>

    ------------------- search-1.html -------------------------

    <html>
    <head>
    <title>Search </title>
    </head>
    <body>

    <iframe src="a.html" height="600" width="600" id="frameSearch ">
    </iframe>

    </body>
    </html>

    ----------------- a.html --------------------------

    <html>
    <head>
    <title>Web Interface</title>
    </head>
    <body>
    <form action="submit" >
    <input type=text name=keywords size=40 value="">
    </form></html>

    -------------- x.js -------------------------------

    function load() {
    var frame = frames[1].document.getEl ementById('fram eSearch');
    var doc = frame.document;
    var elem = doc.getElements ByName('keyword s');
    alert (elem.length);

      function load() {
      var frame = frames[1].document.getEl ementById('fram eSearch');

      Treat frame as a reserved word, use myFrame or so.

      Methinks it is document.frames[0] not [1]

      The frame being loaded does not sigmal that the iframe is loaded.
      Better put some code in the iframe itself,
      or use a timeOut delay [not relyable, loading could be interupted].

      Extensive debugging will probably give you all the answers,
      delete or // the alert()s one by one to reveal any timing problems:


      <input name='keywords' value='myTest'>


      function load() {
      var myFrames = document.frames ;
      alert(myFrames) ;
      var myFrame = myFrames[0];
      alert(myFrame);
      var myIFrame = myFrame.documen t.getElementByI d('frameSearch' );
      alert(myIFrame) ;
      var elem = myIFrame.docume nt.getElementsB yName('keywords ');
      alert(elem);
      alert (elem.length);
      alert (elem[0]);
      alert (elem[0].value);
      };
