Q: I made a html CD presentation based on cascading drop down menu but it works good only onIE and Google Chrome web browsers.
It doesn't work good on Mozilla Firefox browser. It shows menu properly but there is a problem with normal navigation.
The problem is with paths. I put the main js file in "menu" folder and I also have few folders with many html files in them.
For path I use the following "file:/(direct path to specific html file)". It works fine with IE and Google, but Mozilla/Firefox doesn't show the menu.
I tried also to use prefix "file:/" but it also doesn't show the cascading drop down menu on Mozilla/Firefox.
Is there any way to solve this problem?
Thank you for your answer.
A: It is not correct to add "file:/" in the link field.
You should write:
menu/image.gif
or
../menu/image.gif
You can try also to write links in the following way:
file://html/other/1.html
But I don't think that this will help you.
This is a feature of Firefox browser, Opera and Safari. These browsers cannot determine the root folder ofthe website (D:\ in the examples below) on a local machine (as IE and Google Chrome).
IE: D:\html\other\page.html (works)
Opera: file://localhost/html/other/page.html (link doesn't work)
Google Chrome: file:///D:/html/other/page.html (works)
Safari: file:///html/other/page.html (link doesn't work)
Firefox: file:///html/other/page.html (link doesn't work)
You use relative paths (and your folders have several embedded folders), so your links won'twork correctly in Firefox, Opera and Safari. The reason is not in the menu. Standard linkswon't work too.
So I think that the unique solution in your case is to move ALL link files (1.html,2.html, a.html ...) into the same folder with your index.html file.
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 must open a popup with javascript drop down menu, the fact 800X600 popup?
Some links are simple and others are in popup
A: You can open link in the following way:
You can write your own functions within menuItems, for example:
["|MYPAGE","javascript:window.open('http://www.domain.org/mypage.html','_blank','height=600,width=800, status=yes,toolbar=no,menubar=no,location=no');",,,'' ,'' , '', '', ,],
Q: Is there a way to programmatical select an item in the scrolling menu without the user actual click on the item?
A: You can set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
