[Javascript] Accessing atributes - window.opener

Mon Sep 27 14:26:04 CDT 2004

Here I go again...

Now, I've put an input text field on the first page.
With a click in OK, on the opened window, I want to
put a value on this input text field. I tried several
things, like window.opener.document...,
self.opener.document, and so on. None of these worked.

Does anyone know what could be wrong? Thanks.

main.html (calls the pop-up window) :

<HTML>
<HEAD>
  <script src="window.js"></script>
</HEAD>

<BODY onfocus="javascript:checkForDialog();"
id="main"> 
  <a href="javascript:topwind();">Click</a> to open
small window.</p>
  <form id="update">
    <input type="text" name="code">
  </form>
</BODY>
</HTML>

button.html (elements of the pop-up window) :

<HTML>
<HEAD>
  <script src="window.js"></script>
</HEAD>

<BODY onfocus="javascript:checkForDialog();">
<FORM id="select">
  <table cellSpacing="1" cellPadding="2" width="300"
border="0">
    <tr>
      <td colSpan="2">Select option:</td>
    </tr>
    <tr>
      <td></td>
      <td>&nbsp;</td>
     </tr>
    <tr>
      <td>Letters:&nbsp;</td>
      <td>
        <select name="select_l">
          <option value="Option A">Option A
          <option value="Option B">Option B
          <option value="Option C">Option C
          <option value="Option D">Option D
        </select>
      </td>
    </tr>
    <tr>
      <td></td>
      <td>&nbsp;</td>
    </tr>
    <tr>
      <td colSpan="2">
        <P align="center">
          <input type="button" name="but_ok"
value="OK" onclick="javascript:closeWindow();">&nbsp;
          <input type="button" name="but_cancel"
value="Cancel" onclick="">
        </P>
      </td>
    </tr>
  </table>
</FORM>
</BODY>
</HTML>

window.js (contains javascript functions) :

var newWindow;

function topwind()
{
  newWindow =
window.open('button.html','newWindow','toolbar=no,status=no,width=350,height=200')
}

function checkForDialog()
{
  if (newWindow && newWindow != null &&
!newWindow.closed)
  {
    newWindow.focus();
  }
}

function closeWindow()
{
  self.opener.document.update.code.value = "50";
//error here
  //according to mozilla javascript console, this is
the error:
  //  Error: self.opener.document.update has no
properties
  //  Source: file:///d:/guilherme/java/window.js
  //  Line: 18
  self.close();
  self.opener.newWindow = null;
}
