Hi Marc,
thanks for your test scripts.
I have an additional question: As the magic of jQuery lies in chaining,
I wonder if expressions like these could be done with the frame environment:
$("<div>").addClass(currentWfsConf.g_label_id).text(currentWfsConf.g_label).appendTo("#wfsForm");
(Disclaimer: this is untestedcompletely and I hope it's not all bad
jQuery code)
Can you create new tags in the frame, like $("<div>", parent)?
Can you use the appendTo with a context parameter?
I failed, but I may not yet have seen the light.
Thanks for your contribution,
Christoph

Hi devs,
as discussed on monday there are certain things to be considered when
you want to use jQuery. Please rebuild this testcript(s):
File 1 (the parent | mainframe in Mapbender):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd";>
<html>
<head>
<title>Test</title>
<script src="./tree21/jquery-1.2.1.pack.js"
type="text/javascript"></script>
</head>
<body>
<iframe src="test2.php">
</iframe>
<div id="parentdiv">I shall disappear first</div>
</body>
</html>
File 2 (the child | any frame embeded in Mapbenders mainframe):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd";>
<html>
<head>
<title>Test</title>
<script type="text/javascript">
/**
* Map over parent's jquery to this frame's "$"/"jQuery".
* Keep the second parameter to work in other contexts.
*
* @todo check thoroughly.
* @author Marc Jansen <[EMAIL PROTECTED]>
*/
if (typeof $ == 'undefined' && typeof parent.$ != 'undefined' &&
typeof jQuery == 'undefined' && typeof parent.jQuery != 'undefined') {
jQuery = function(param, context) {
return parent.jQuery(param, context || window.document);
};
$ = jQuery;
}
// a test setting
window.setTimeout(function() {
alert('working in parent');
$('#parentdiv', parent).each(function() {
alert(this);
}).hide();
alert('working in child');
$('#iframediv').each( function() {
alert(this);
}).hide();
alert('has everything disappeared?');
}, 3000 );
</script>
</head>
<body>
<div id="iframediv">I shall disappear later</div>
</body>
</html>
Try to rebuild the two files and you'll understand what is happening
here. Needs to be checked in detail!
I suggest to test this further and to use this:
/**
* Map over parent's jquery to this frame's "$"/"jQuery".
* Keep the second parameter to work in other contexts.
*
* @todo check thoroughly.
* @author Marc Jansen <[EMAIL PROTECTED]>
*/
if (typeof $ == 'undefined' && typeof parent.$ != 'undefined' &&
typeof jQuery == 'undefined' && typeof parent.jQuery != 'undefined') {
jQuery = function(param, context) {
return parent.jQuery(param, context || window.document);
};
$ = jQuery;
}
when you want to use jQuery.
Bye,
-- Marc
