Q: Please tell me where I am going wrong:
The menu is all messed up!
A: See, now you have:
var itemBackImage=["data.files/btn_green.gif","data.files/btn_whitegreen.gif"];
and you also assign Individual Item Style with itemBackImage anditemWidth parameters for each item
var itemStyles = [
["itemWidth=92px","itemBorderWidth=0","fontStyle=normal 11px Tahoma","fontColor=#000000,#000000",
"itemBackImage=data.files/btn_whitegreen.gif,data.files/btn_white_white.gif"],
];
var menuItems = [
["projects","", , , , , "0", "0", , ],
["FMWR","", , , , , "0", "0", , ],
["general water info","", , , , , "0", "0", , ],
["bulletin board","", , , , , "0", "0", , ],
["WSS MDG tracking","", , , , , "0", "0", , ],
["reform instruments","", , , , , "0", "0", , ],
You should delete itemBackImage and itemWidth parameters from itemStyles.
Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
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: I am still struggling with multiple menus on one page.
It is probably something I am doing wrong, but I cannot see it.
A: Now you have:
var absolutePos=1;
var posX="10";
var posY="10";
So, both of your menus have the same absolute position.
You can use relative position and place your menu inside <table>. In this case you should write so:
var absolutePos=0;
Q: I am spending a lot more time and have figured a few things out. One more question please: How do I specify the target link I want a dhtml submenu to go to?
I see HREF specified in the code, but no where in the program to specify it.
A: See, the following parameter sets target for all items
var itemTarget="_self";
If you want to set different target for each item you should set it inthe "Item Parameters" window. Choose your item in the main window andset target in the target field.
