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.
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"

Q: I will build menu for several books’ Contents, each book is more than 100 lines and has links. I think if all the books’ contents in 1 *.JS file then it is TOO LOONG!!.
Can I break it down to 1 book for 1*.JS ? How?
A: You cannot divide your menuItems parameter.
You can only use one .js file for your menu parameters and the other.js file for your menuItems = [...];
But you can do it in two ways.
1) You can try to use several menus on the one page, for example:
param.js // file with menu parameters (all parameters before menuItems = [...];)
menu1.js // menuItems for "AC-DC", "ANLOG"
menu2.js // menuItems for "DIGITAL", "WinXP"
menu3.js // menuItems for "MS-Word", "MS-Excel"
In these menu files you should write
menuItems = [
...
];
dm_init();
Then you should install your menu in the following way
<script type="text/javascript" src="param.js"></script>
<table>
...
<script type="text/javascript" src="menu1.js"></script>
...
<script type="text/javascript" src="menu2.js"></script>
...
<script type="text/javascript" src="menu3.js"></script>
But it will be easier to use vertical menu in such case
var isHorizontal=0;
var smColumns=1;
2) You can also try to add some code, see the attached example.
In the first file (@MY books (Multiple Col.js) I write menuItems for the first item "AC-DC".
Notice that you should delete comma at the end of the last item
var menuItems = [
["AC-DC","", , , , , , , , ],
["|@Book1","testlink.htm", , , , , , , , ],
...
["|@Book3","", , , , , , , , ],
["||CH02","", , , , , , , , ],
["||CH01","", , , , , , , , ] // delete comma at the end of the last item
];
In the second file (@MY books (1.js) you should write
menuItems = menuItems.concat(
[
["ANLOG","", , , , , , , , ],
["|@Book1","", , , , , , , , ],
["|@Book2","", , , , , , , , ],
["|@Book3","", , , , , , , , ] // delete comma at the end of the last item
]
);
In the third file (@MY books (2.js) you should write
menuItems = menuItems.concat(
[
["DIGITAL","", , , , , , , , ],
["|Item 1332","", , , , , , , , ],
["WinXP","", , , , , , , , ],
["|Item 1333","", , , , , , , , ],
["MS-Word","", , , , , , , , ],
["|Item 1334","", , , , , , , , ],
["MS-Excel","", , , , , , , , ],
["|Item 1335","", , , , , , , , ] // delete comma at the end of the last item
]
);
dm_init();
Notice that you should write dm_init(); function in the last file.
In the .html file you should write
...
<tr>
<script type="text/javascript" src="@MY books (Multiple Col.js"></script>
<script type="text/javascript" src="@MY books (1.js"></script>
<script type="text/javascript" src="@MY books (2.js"></script>
</tr>
I hope you understand me.
Q: I'm trying to implement your javascript menu source on a clients' web site.
If you go to my website you'll see my problem. I can't get javascript menu source to centre in the table I want it to - which is just below the header flash in between the two yellow lines.
Could you let me know what to do - then I can show it to my client and order it!
A: Now you're using absolute position for javascript menu source:
var absolutePos=1;
You should use relative position:
var absolutePos=0;
Q: I got the menu to display across frames, but it displays differently in Firefox & Mozillavs. Internet Explorer. Is that to be expected?
In The Mozilla-based browsers, the submenu butts right upunder the main menu – which is how I want it. In IE, it is about 10 pixels below.
Also, I can’t get the submenus to drop down directly under the main menus – they are offset by about 100 pixels to the right.
A: The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, sosubmenus drop down with an offset.
You should create the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine awidth of the 1st column in the second row.
