Q: Do you have an extremely simple example of modifying a menu with the JavaScript API? I've played with the example on the site, but I have trouble removing the other menus without breaking it.
I just want to use the API to change the icon on the menu items.
A: You should use the following function:
function dm_ext_changeItem (menuInd, submenuInd, itemInd, iParams)
<script language="javascript" >
dm_ext_changeItem(0, 0, 1, ["", "", "new_icon.gif", "new_icon_o.gif", "",,""]);
</script>
Q: This is the problem I need to solve.

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>
Q: What I would like to see is the ability to have a base site navigation menu with all the definitional entries (size, locations, icons, etc.) defined but all the menuitems be called from an Ajax file.
A: You cannot use ajax submenus for the top items.
But you can use several .js file, for example:
params.js //file with all menu parameters (size, locations, icons, etc.)
all code before
var menuItems = [
...
];
dm_init();
data_ajax1.js //data files for ajax submenus
data_ajax2.js
data_ajax3.js
...
main_data.js - data file with the following code:
var menuItems = [
["Item 1","", "", "", "", "", "0", "0", "data_ajax1.js", "", "", ],
["Item 2","", "", "", "", "", "0", "0", "data_ajax2.js", "", "", ],
["Item 3","", "", "", "", "", "0", "0", "data_ajax3.js", "", "", ],
["Item 4","", "", "", "", "", "0", "0", "data_ajax4.js", "", "", ],
];
dm_init();
You can also place this code into your html page directly (in the place where you want tohave a menu):
<script type="text/javascript">
var menuItems = [
["Item 1","", "", "", "", "", "0", "0", "data_ajax1.js", "", "", ],
["Item 2","", "", "", "", "", "0", "0", "data_ajax2.js", "", "", ],
["Item 3","", "", "", "", "", "0", "0", "data_ajax3.js", "", "", ],
["Item 4","", "", "", "", "", "0", "0", "data_ajax4.js", "", "", ],
];
dm_init();
