Q: When we use dhtml menus on our pages it appears behind Flash objects.
A: You should add "opaque" parameter for <object> and <embed> tags.
See, how you should install flash on your pages.

Q: I created a custom error page for a site, but the menu would not display.
I found that this was due to the erroneous "current directory" in the bad link test, for a non-existent directory.
which is: level2/level3/
I changed the script code from:
<script type="text/javascript"> var dmWorkPath = "DMworkfiles/";</script>
<script type="text/javascript" src="DMworkfiles/dmenu.js"></script>
to:
<script type="text/javascript"> var dmWorkPath = "DMworkfiles/";</script>
<script type="text/javascript" src="/DMworkfiles/dmenu.js"></script>
adding the "/" before "DMworkfiles/dmenu.js" source reference allowed the .js file to be found in the root directory and the menu would display.
The problem is that the little menu "expansion" arrow .gif cannot be found in the "current working directory" of level2/level3/. just little "blanks" show.
I tried changing:
var dmWorkPath = "DMworkfiles/";
to:
var dmWorkPath = "/DMworkfiles/";
but that did not enable the display of the arrows.
I also had to prefix all of the links in the menu with a "/" to indicate the root directory because of the "current directory" for the bad page.
I hope I have explained the problem sufficiently.
What am I doing wrong or missing here?
A: You can use additional parameters to make menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.
For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters
Q: Can I change the style of javascript tree menu on the fly when I click the style menu items of the tree I made?
A: Theoretically you can do it.
Try to use
function dtreet_ext_userClick(itemID)
{
// Your Javascript code here
return true;
}
function and call
function dtreet_ext_changeItem (menuInd, itemID, itemParams)
function in it.
You should create Individual item style for this item and and assignthis style when you click on the item
Q: Couple last questions. I have 25 icons (images) on one page. Each image needs it's own popup menu. Obviously I now have the first one working. How and where do I define IDs number 2-24 ? Does each icon need it's own "source_" file?
Also, where is it defined that the popup menu is ID 1 ?
A: > Also, where is it defined that the popup menu is ID 1 ?
Each menu has ID. The ID's number starts with 0.
So, when you have several data files on your page you have such ID's:
<script type="text/javascript" language="JavaScript1.2" src="menu-top.js"></script> // ID - 0
<script type="text/javascript" language="JavaScript1.2" src="source_pop.js"></script> // ID - 1
<script type="text/javascript" language="JavaScript1.2" src="source_pop1.js"></script> // ID - 2
<script type="text/javascript" language="JavaScript1.2" src="source_pop2.js"></script> // ID - 3
<script type="text/javascript" language="JavaScript1.2" src="source_pop3.js"></script> // ID - 4
and so on.
> I have 25 icons (images) on one page. Each image needs it's own popup menu.
If you want to have different Popup menus (there color, item, text,font and so on) you should create 25 different .js files with yourparameters. And call them from your page, for example:
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript1.2 src="source_pop1.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript1.2 src="source_pop2.js" type=text/javascript></SCRIPT>
...
<SCRIPT language=JavaScript1.2 src="source_pop24.js" type=text/javascript></SCRIPT>
If you have different item text only you can use one
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
file. But you should delete the following code:
var menuItems = [
["Next","testlink.htm"],
["Prev","testlink.htm"],
["Close","testlink.htm"],
];
dm_init();
and move it to the html page:
<body>
...
<SCRIPT language=JavaScript1.2 src="source_pop.js" type=text/javascript></SCRIPT>
<script type="text/javascript"> //first popup menu ID - 1
var menuItems = [
["Next","testlink.htm"],
["Prev","testlink.htm"],
["Close","testlink.htm"],
];
dm_init();
</SCRIPT>
<script type="text/javascript"> //second popup menu ID - 2
var menuItems = [
["Text","testlink.htm"],
["Text1","testlink.htm"],
["Text2","testlink.htm"],
];
dm_init();
</SCRIPT>
<script type="text/javascript"> //third popup menu ID - 3
var menuItems = [
["New_Text","testlink.htm"],
["New_Text1","testlink.htm"],
["New_Text2","testlink.htm"],
];
dm_init();
</SCRIPT>
...
<script type="text/javascript"> //twenty fourth popup menu ID - 3
var menuItems = [
["New","testlink.htm"],
["New","testlink.htm"],
["New","testlink.htm"],
];
dm_init();
</SCRIPT>
<img src="testimage.gif" width=200 onClick="return dm_popup(1, 1000, event);" style="cursor: hand;">
<img src="testimage.gif" width=200 onClick="return dm_popup(2, 1000, event);" style="cursor: hand;">
<img src="testimage.gif" width=200 onClick="return dm_popup(3, 1000, event);" style="cursor: hand;">
...
<img src="testimage.gif" width=200 onClick="return dm_popup(24, 1000, event);" style="cursor: hand;">
...
</body>
