Q: I try to use the javascript menu popups to show an image; then when the mouse is over the image I dynamically generate a panel of http links. It works perfectly, but the problem is that I would like to do the same with several images (for instance 2) and different links : I'm not able to do that, whether I change the value of menuItems var or not, I display the same link values on both images (it seems menuItems is a global var and can be set only once).
Have you heard about this problem and could you give me a solution (this is a bit urgent, I have sold this solution to my customers) ?
A: See how you should call dm_popup() functions:
<img src="../../../../fileadmin/img/flag_de.gif" width="50" onMouseOver="return dm_popup(0, 2000, event);" style="cursor: pointer;">
// 0 - is ID of the first menu
....
<img src="../../../../fileadmin/img/flag_fr.gif" width="50" onMouseOver="return dm_popup(1, 2000, event);" style="cursor: pointer;">
// 1 - is ID of the second menu
// 2 - is ID of the third menu
... and so on.
Q: Typically in order to generate a menu with multiple layers I’d put a pipe character in front of the menu text.. For example:
["|Page Admin","/admin/handoutadmin.php", , , , "_new", , , , ],
["||Student Pages","/admin/handoutadmin.php?type=1", , , , "_new", , , , ],
["||Teacher Pages","/admin/handoutadmin.php?type=2", , , , "_new", , , , ],
["||Family Letters","/admin/handoutadmin.php?type=4", , , , "_new", , , , ],
["||Transparencies","/admin/handoutadmin.php?type=3", , , , "_new", , , , ],
However, when I try to do it with dm_ext_addItem it actually SHOWS the pipe character and doesn’t create any menu levels at all.
For example:
dm_ext_addItem(0, 0, ["Add a Handout to this Lesson", "", "", "", "", "", ""]);
dm_ext_addItem(0, 0, ["|Student Page","/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
dm_ext_addItem(0, 0, ["|Teacher Page","/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
How can I generate multiple levels of the menu with javascript?
A: I suppose that your code is not valid
dm_ext_addItem(0, 0, ["|Teacher Page", "/admin/handoutadmin.php?type=$type", "", "", "", "_new", ""]);
Try to write it in the following way:
dm_ext_addItem(0, 0, ["|Teacher Page", "/admin/handoutadmin.php?type=", "", "", "", "_new", ""]);
Q: I can't see my javascript vertical tree menu in FireFox. What I'm doing wrong?
A: You should set this parameter:
var tmenuHeight = "auto";
Now you have
var tmenuHeight = "0";
Q: I’m trying to setup a simple DHTML MENU (TREE MENU). It works just fine. I just have an issue that I can’t solve.
The parameter “ var tmenuHeight = "0"; Your documentation says the following
-----------
Height of the menu in (px, % or other units).
If the value 0 - the menu sets its height automatically.
If the value is small - scrollbars appear.
In IE it looks fine but I cannot see the menu in Firefox. When I set the parameter to for example 100 then it shows up both in IE and Firefox. But I cannot set a value in pixels. I don’t know how big the menu is because it’s dynamically built. According to your doc I can specify the value in percentage but this doesn’t work. When I set the value to “100%” it doesn’t show up in Firefox again.
How can I solve this issue?
A: Try to set this parameter in the following way:
var tmenuHeight = "auto";
