I've been running some small test programs which seem to indicate
something noticed in a larger script, that a function called from
onLoad() in the <body> tag will not succeed in creating a window
(i.e. successfully executing window.open() in Mozilla 1.5; however,
I've observed it to work a few times in IE 6.0 and Opera 5.something.
It does not seem to be a timing thing -- if I re-call the function
somewhat later using setTimeout it still doesn't succeed. However,
a call to the same function from a link (a href=...) does succeed.
I'm wondering if I've overlooked something in the documentation.
The shortest of the tests:
-----------------------------------------------------------------
<html>
<head>
<title>x</title>
<script language="JavaScript1.2" type="text/javascript">
var k = 0;
var m = 'w1.<br>';
var w1;
function initz() {
k += 1;
if (w1) {
m += k + ": already here! ";
} else {
m += k + ": opening... ";
w1 = window.open(" ", "w1",
"toolbar=no,status=yes,height=400,width=400,menuba r=yes,scrollbars=yes,resizable=yes,directories=no, location=no");
}
if (!w1) {
m += k + ": not here.... ";
} else {
m += k + ": here! ";
w1.document.write("m=" + m + "<br>");
}
}
</script>
</head>
<body bgcolor='#53438F' text='#ffff00' link='#ff0000' vlink='#cc0000'
onload='javascript:initz()'>
<a href='javascript:initz()'>
xxx</a>
</body>
</html>
-----------------------------------------------------------------
which, when the link is clicked on, brings up a window with
the following text:
m=w1.
1: opening... 1: not here.... 2: opening... 2: here!
