Hi,
I'd like to write my opinion quickly.. My way both usable with and without
JS...
In my structures there is an array of the menu elements similar to:
$menu[gravity][name] = link; - filled from database, easy to handle
to more prof., more params use three-dimensional array...
In the url u can store the selected/expanded (sub)menu but without js its a
little bit slow cause of reload. (good way if js is blocked and users have
high speed conn. or page cached well...)
eg. home?expand=menu_item_id
if (this_menu_item == expanded_item){
show submenus...
}
u can also generate js from php.. or set height, visibility from js for a
*div uploaded from php*...
create an array or use simple innerHTML to show the menu... I suggest
skipping all the js examples (because they are too complicated) and write a
simple script from your mind using basic elements...
eg. simply you have to have a global array...
expanded[menuid] = true;
if (expanded[menuid]){
//innerHTML = "submenus";
menu_item.style.height = "auto";
menu_item.style.visibilty = "visible";
}
or expanded[] = id; //using in_array...
and yes, u can use AJAX to load php to js...
Simple JS code I wrote before it:
function subs(id, len){
var subsa = document.getElementById(id);
var subsap = document.getElementById(id + 'p');
if (subss[id] == true){
subsa.style.visibility = "hidden";
subsa.style.height = "10px";
subsap.innerHTML = "[+]";
subss[id] = false;
} else{
subsa.style.height = (len * 18) + "px";
subsa.style.visibility = "visible";
subsap.innerHTML = "[-]";
subss[id] = true;
}
}
used for:
Menu[-]
Sub
Sub
Menu[+]
Menu[+]
*Have a good time with PHP!*
