Recent Questions How To Manage Trees With Javascript
Q: Buttons are working great! Client would now like to have the rollover image stay active on the page they are on. They would like the button to stay white when you navigate to a particular page, i.e. If you click on "Press", when you get to that page, the button stays white, while all the others react in the normal manner. Is this possible?? I have seen it on other sites and it seems like it should be possible. Please let me know. I believe it could be done by creating a separate menu for each page, but that seems like a lot of work. I am sure you have a solution.
A: The menu has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<noscript><a href="http://deluxe-menu.com">Javascript Menu by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also 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.
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";
Q: I’ve tried every configuration available—absolute and relativepositioning and so on. I can’t get the menus to display correctly.
I have to offset the topDX by -150 and so on just to fudge it into a CLOSE position…it certainly doesn’t mirror the preview window
A: See, the problem is that the script can't get css properties of the object if they are described in separate .css block (or file).
In other words, you can't get the value of "position" attribute of the object if the object doesn't have this property within inline style(style="position:absolute"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
You should add style="position:absolute;"
to the
<DIV id=navholder>
So, you'll have:
<DIV id=navholder style="position:absolute;">
Q: My question is, the down arrows only show on the main page, how do I fix this.
A: Please, check images paths within data .js file.
For example, if you have data.js file here:
c:/website/data.js
and your images are stored here:
c:/website/images/
you should set image name so (for example):
var arrowImageMain = ["images/arrow1.gif", "images/arrow2.gif"];
If you use Tuner, you should save data .js file before you'll selectimages. When you save .js file it means that you set a root directoryfor the project, so Tuner can make all selected images with relativepaths.
