Q: I have a transparent dhtml menu located at the bottom of the page with just one level of submenus. On larger screens, the submenus open either upwards or downwards, depending on how many items are in the transparent dhtml menu.
Can I set the submenu's to always open upwards?
A: Try to set the following parameter:
var subMenuVAlign="top";
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: I need to know if it is possible to call a JavaScript function from the cool dhtml menu.
I have read the FAQ and noted where it lists that you can perform an alert call, and that worked on my end as well, but when Iattempted to call a function I created I could not get it torespond.
Is it possible to call a function from your menu?
Could Iget an example?
A: You can write your own functions within menuItems, for example:
["|Real-Time Data Query","javascript:window.open('http://www.domain.org/','_blank','height=758,width=1024,status=yes,toolbar=no,menubar=no,location=no');"
,,,'Query real time water quality data' ,'' , '', '', ,],
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.
