Recent Questions Javascript Accordion Tree Sample
Q: We are unable to get sub-menus to appear on page load or rather simulate a "windows application style menu".
How can we in combination with the java menu api function dm_ext_setPressedItem get the associated sub-menu to display? This function simply sets the item to "pressed" rather than actually showing the sub-menu. Attempts at beginning an item's text value with "+" only works with Javascript/DHTML Tree.
Again, we are trying to use the menu not only as a navigator but also as a visual aid for the user to determine what page they are viewing. For example, when a user clicks on a menu item and that page loads, the menu should display the top-level item pressed, the sub-menu group, and the item pressed.
Furthermore, it would also be useful if we could then "unlock" the pressed items and navigate the menu under normal circumstances.
If there are no existing "quick" functions to accomplish this, could you please point out the function in dmenu.js or another engine file that initiates the display of sub-menus, we could then force the menu to select a top-level item in the onload event thus showing a top-level item pressed along with it's related sub-menu.
A: Unfortunately JavaScript Tree Menu doesn't have such a feature now. It is notpossible to set parent item highlighted, expanded submenu group andhighlighted submenu item.
You can do it using Javascript/DHTML Tree now only.
Q: Some menu entries may be disabled and clicking on them should produce predefined javascript alert message?
A: To create disabled items you should set "_" symbol in the targetparameter of the menuItems.
If the target is "_" the item is disabled.
You can assign a font color for all disabled items using the following menu parameter:
var fontColorDisabled = "#AAAAAA";
You can write a javascript code instead of an item link:
["item text", "javascript:alert('Hello World')", , , ,"_",]
That's all.
Q: The menu files need to be in EVERY directory that there is a page calling these files?
A: No you can use one folder with engine .js files.
But in your html pages you should write correctly your dmWorkPathparameter:
< script type="text/javascript"> var dmWorkPath = "./menudir/";</script>
and call dmenu.js file from the right place
<script type="text/javascript" src="./menudir/dmenu.js"> </script>
Q: A few of my users have reported issues with the menu like the one below. Where the drop down menu is just a white box with a little scroll bar in it. Can you please let me know how I might correct it or what is wrong? We are using version 2.4.
A: I've just checked your website. It works fine.
You can have such effect when the page entirely was not loaded yet. So, images were not loaded yet.
If you don't want to have such effect you can try not to use back images for the submenus.
