Hi
I'm attempting to update some information in a form using an external
reference to a window opened using the open() method.
My test scripts look something like (deb_prn simply writes to a debug window) :
WinOpTst.htm - file containing the code to open the window
----------------------
<script language="javascript" type="text/javascript"><!--
var popPgWin = window.open("popPgTst.htm", "PopPgTst");
deb_prn("popPgWin.document.forms.length = " + popPgWin.document.forms.length);
deb_prn("popPgWin.document.forms[0].name = " +
popPgWin.document.forms[0].name);
deb_prn("popPgWin.document.forms.length = " + popPgWin.document.forms.length);
deb_prn("popPgWin.document.forms.TextBox1.value = " +
popPgWin.document.forms.form1.TextBox1.value);
//--></script>
popPgTst.htm
----------------------
<body>
<form name="form1">
<input type="text" name="TextBox1" value="Hello" size="20"></input>
</form>
</body>
When I open WinOpTst.htm in IE 5 the output I get is :
popPgWin.document.forms.length = 0
popPgWin.document.forms[0].name = form1
popPgWin.document.forms.length = 1
popPgWin.document.forms.TextBox1.value = Hello
... which is almost what I expect, except for some reason the length of
forms[] returns 0 until the form itself has been accessed.
When I open it in Netscape 7.0 the output is :
popPgWin.document.forms.length = 0
and there is an error message saying ' popPgWin.document.forms[0] has no
properties'
Does anyone know what is going on here and how I can access the form in
Netscape ?
Cheers
Larry
