Q: I used the drop menu creator to create a simple tab example, and I created a simple HTML file to display the tabs. It initially appears fine when the page first displays (e.g., the correct div is hidden), but when I *first* click on a tab I always get a javascript error deep in the .js code. Then I click around a bit between the tabs and get some display problems (no more javascript errors though), until finally the show/hide logic recovers and all looks ok.
The error I initially get is something like “tabs[…].id is not an object”. I have the IE7 debugger turned on, otherwise I might not ever see this error.
FYI, I tried your example menus on your web site and everything is fine! Maybe the .js files on your web site are not the same as those created by the generator?
A: You should set the following parameter in drop menu creator:
var bselectedSmItem=0;
Q: When I open my site in Internet Explorer 6.0 the main drop menu code shows up nicely but the drop-down sub-menus are separated. The drop menu code work very nicely in a Firefox browser but not in IE.
A: There are some problems also with your css.The problem is that the drop menu code can't get css properties of the object if they are described in separate .css block (or file).
In other words, you can't get the value of "position" attribute of the object if the object doesn't have this property within inline style(style="position:relative"). To get the value you should move .css style into style="" attribute.
Please, try to add your
css file -> inline css, for example:
You should add style="position:relative;"
to the
<DIV id="right">
So, you'll have:
<DIV id=right style="POSITION: relative;">
Check that.
Q: Greetings. How do I make a menu item as default selected and open when the page loads with the dhtml menu bar script? Thanks.
A: JavaScript Tree Menu has only two states normal and mouseover.
Try to do the following things:
- delete var pressedItem=1; parameter from your data file
- set correct parameter on each page before you call data file, forexample:
<noscript><a href="http://deluxe-menu.com">dhtml menu bar script by Deluxe-Menu.com</a></noscript>
<script type="text/javascript"> var dmWorkPath = "menudir/";</script>
<script type="text/javascript" src="menudir/dmenu.js"></script>
<script type="text/javascript"> var pressedItem=3;</script>
...
<script type="text/javascript" src="menudir/data.js"></script>
You can also set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a dhtml menu bar script on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem. You can't get this ID after you reload your page. That is why you should write your own code on PHP.
Q: I've begun experimenting with the dhtml rollover menu program and like what I see.
Question, when I have a tree menu on the left and the user clicks a node, I want the resulting HTML page to appear next to the dhtml rollover menu, on the right hand side. How do I reposition the HTML page so it doesn't take up the whole page and cover the menu?
A: You can use frames and open link pages into the content frame, or use Iframe.
Please, set the name for your iframe, for example:
<iframe name ='myFrame' ...
<frame name ='myFrame' ...
And then you must set the following dhtml rollover menu parameter in the data file withyour menu:
var titemTarget="myFrame";
