Hi all,
Evan and mindplay.dk at the Mootree user's group gave me some tips,
and I finally solved the problem. Here's my solution (for the original
thread see
http://groups.google.com/group/mootree/browse_thread/thread/338d346b786bbafd/c62788485e55005c?lnk=st&q=mootree):
The main error was that I've defined the menutree in the window.load
event, because this caused the CONSTRUCTOR of menutree to be called
every time the load.event occured, and gave me several instances of
menutree instead of rebuidling and overwriting the first. Obviously,
that's not the right way, so, I've rewritten my code, and now it looks
like below, and works.
var js_navigation = {
menutree : new MooTreeControl({
div: 'navigation',
mode: 'files',
grid: true,
theme: 'mootree2/mootree.gif',
//other stuff like select handlers, etc.
},{
text: 'Menu',
open: true
}),
};
js_navigation.menutree.root.clear();
js_navigation.menutree.root.load('functions/loadmenu.php?
action=loadtree');
One word to mootree's div-handler: Normally, I load all JS functions
by including them in the HTML header - that will not work if you
define your tree like I did, because the div for the tree (in my code,
"navigation") is not defined in the header, so, Mootree cannont adopt
it. So, it's better to include the JS at the bottom of the body, where
all divs are defined.
Also took me a few minutes to figure this out...
