    ReferencError: Parent is not defined

    I have a html page that has an inframe very similiar to the one Jim Ley
    put out at:
    http://jibbering.com/2003/8/iframetest.html


    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <title>Test by TM 08/03</title>
    </head>
    <body>

    <iframe name="kreise" src="kreise.svg " width="500" height="100"
    frameborder="0" >
    content for browsers without SVG access ...
    </iframe>

    </html>

    The only difference is that the user is clicking on a link in
    kreise.svg to get the parent document. I get "ReferencEr ror: Parent is
    not defined"

    kreise.svg would look like:

    <svg width="1024px" height="626px" onload="initsvg (evt);" viewBox="0 0
    1024 626" preserveAspectR atio="none" xmlns="http://www.w3.org/2000/svg"
    xmlns:xlink="ht tp://www.w3.org/1999/xlink"
    xmlns:a3="http://ns.adobe.com/AdobeSVGViewerE xtensions/3.0/"
    a3:scriptImplem entation="Adobe ">
    <title>Graphi c</title>
    <defs>
    <script language="JavaS cript">
    <![CDATA[
    var svgObj;
    function initsvg(evt)
    {
    if ( window.svgDocum ent == null )
    {
    svgDocument = evt.target.owne rDocument;
    }
    svgObj = svgDocument.doc umentElement;
    }
    function close_graphic(e vt)
    {
    var obj;
    obj=parent.fram es["kreise"];
    alert(obj);

    //parent.document .getElementById ('kreise').styl e.visibility='h idden';
    }
    ]]>
    </script>
    </defs>
    <a onclick="close_ graphic(evt);">
    <text x="35" y="35" font-family="Arial" font-size="20" fill="#ff0000"
    pointer-events="all">Cl ose</text>
    </a>
    </svg>

    Anyone have any idea why this does not function?

          I think that really is "ReferenceError : parent is not defined".

          `parent' is a known property of Window objects. You are assuming falsely
          that the object referred to by `window' in some HTML DOMs necessarily
          refers to the Global Object, and that the Global Object in the SVG DOM
          is a Window object. Try `window.parent' instead.

              Re: ReferencError: Parent is not defined

              I tried:

              var obj;
              obj=window.pare nt;
              alert(obj);

              and the error message is:

              "uncaught exception: [SOMException 3: Parameter type mismatch: 1]"

                  Well, then you will have to find other means in the DOM of the SVG context
                  you are working in (which UA, which plugin?), or there is simply no means
                  to refer to the "parent" window in that DOM.

                      Re: ReferencError: Parent is not defined

                      I found an example of where I would define what looks like a link into
                      the document. Instead of using an iframe they used an <embed> tag. I
                      included this in my example below as well as the js definition of
                      htmldocument

                      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
                      <html>
                      <head>
                      <title>Test by TM 08/03</title>
                      </head>
                      <body>
                      <SCRIPT language=javasc ript>
                      var htmldocument=do cument
                      </SCRIPT>
                      <iframe name="kreise" src="kreise.svg " width="500" height="100"
                      frameborder="0" >
                      content for browsers without SVG access ...
                      </iframe>
                      <embed width="200" height="100" src="controls.s vg">
                      </html>

                      Then in the controls.svg there is an init function like:

                      <script><![CDATA[
                      var svgdoc='',root= '';
                      function init(evt)
                      {
                      svgdoc=htmldocu ment.embeds[0].getSVGDocument ();
                      root=svgdoc.fir stChild();
                      }
                      ]]></script>

                      So, for my use in an iframe it seems like I would use:

                      svgdoc=htmldocu ment.frames[0].getSVGDocument ();

                      except I get: "ReferenceError : htmldocument is not defined"

                      Any thought on that?

                              sounds about right. what was it supposed to do?

                                  I don't think window implements the value property...
                                  (and so there's nothing for the alert to print)

                                  upto the alert your code is fine.

                                  Bye.

                                      I'm just trying to get to the window functions so I can open and close
                                      some windows but I can't get there from in a document with this
                                      heirarachy:

                                      document | iframe | svgdoc
