Q: What can I do to optimize the load time for dhtml rollover
and prevent reloading it from the server with every page reload.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: How do I make the background in my rollover drop down menu transparent?
A: You should set the following paramter in your data.js file:
var tmenuBackColor="transeparent";
Q: How can I open the links that I created for the web drop menu /sub-menu on the same window (not on a new window)
A: You can set target parameter for all items:
var itemTarget="_self";
or for each item individually:
["","testlink.htm","http://images.myregistry.com/images/myregistry/tabs/thingstodo.gif", "http://images.myregistry.com/images/myregistry/tabs/thingstodo1.gif", "Home Tip","_self", "0", "0", , ],
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.
