Recent Questions Constructing Treeview Using Javascript Code
Q: I am trying to placed a separator image in between each item in my css vertical dropdown menu. I have placed the image in the seperator field and it will not display. How can I get an image to be a separator in between items on my css vertical dropdown menu?
A: To add a separator you should
//--- Separators
var separatorImage=""; //for subitems (top items in css vertical dropdown menu)
var separatorWidth="100%";
var separatorHeight="3px";
var separatorAlignment="right";
var separatorVImage="separator.gif"; //for the top items (subitems items in css vertical dropdown menu)
var separatorVWidth="100%";
var separatorVHeight="2px";
var separatorPadding="";
You can create separators using menuItems (you can do it in DeluxeTuner, use "Add separator" button), for example:
var menuItems = [
["item 1"],
["-"], // this item is separator
["item 2"],
];
Q: Hi, I need to know if it is possible to accomplish the following functionalities with your tree-menu library.
1. I need to have two or more trees in the same page
2. I need to have a checkBox in each node and through a JavaScript function be able to add the selected nodes into another tree.
3. I need to eliminate the nodes that has check=true
4. I need to populate on-demand the tree using AJAX
5. I need to implement drag&drop through the use of the mouse events on the tree nodes
6. How would the tree behave with 10000 nodes??
7. I need to have a tree within another element that uses scroll
such as a DIV or SPAN (fixed area). When collapsed or expanded, the area should remain its original size.
A: 1. You can add any number of the menus on the one page.
2, 3, 5. Yes, you can do it. But you should create your own server-side script (for example, php) that will do it. The menu doesn't support such a feature.
4. Unfortunately, you can't use the AJAX-like technology in the Javascript/DHTML Tree such as in JavaScript Tree Menu.
6. It is possible that the loading speed can be lower if the menu is very large. But it doesn't take so much time.
Yes, you can notice some delay in IE, but in over browsers it works better.
Javascript/DHTML Tree works fast, but 10000 is a large value. Please, try atrial version of Javascript/DHTML Tree.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
7. You can paste Javascript/DHTML Tree into the <table> or <div>.
Q: I have created aKaspersky menu, but the links don't work.
A: See, you can use links if you have
var tabMode=1;
only.
If you have
var tabMode=0;
You should use the ID of the DIV.
But you can try to open your pages using different targets in thefollowing way
["tab text", "javascript: window.open('test.html', 'frameName')", ...],
["tab text", "javascript: window.open('test.html', '_self')", ...],
["tab text", "javascript: window.open('test.html', '_blank')", ...],
Where frameName - the name of the frame where to open the page test.html.
Using this method you can create Deluxe Tabs in var tabMode=0; and var tabMode=1;
Q: We purchased the JavaScript Tree Menu a few months ago and are extremely happy with the product. We have been getting great compliments about our new navigation system.
The menu has over 500 links and functions like a dream! One issue I am having, that I just cannot seem to figure out how to fix, is the following:
Our nav menu is displayed approx. 70 pixels from the top of the browser window. On the drop down links that have a number of items (example 1 in the image below), they display underneath the menu, however on the links that have only a few items, they display above the menu bar in java script as in example 2 in the image below.
How can I set it so that no matter how many drop-down items there are, they always display under the menu bar in java script, not on top?
A: Try to set the following parameter:
var subMenuVAlign="top";
