Q: I have tested your JavaScript Tree Menu Builder and found it easy to work with.
One problem I have is that java menu freeware doesn’t support Swedish letters. When I preview the menu in a browser instead of those specific Swedish letters there are squares.
Could you please inform what I can do? Are there some setting I can change to use Swedish letters?
I am looking forward to hearing from you soonest possible.
A: You're able to use any characters for JavaScript Tree Menu in the same way asyou use them for standard html page.
Unfortunately, you can't use Swedish letters in Deluxe Tuner application.You should manually correct your data file with the menu parameters.
Q: Please identify the parameter I need to set to produce ... Tree menu items start out as normal text , then Bold text for tree menu items on the onmouseover event . After mouse out, text returns to normal.
A: Unfortunately, Javascript/DHTML Tree doesn't have such a feature. You should addthe following code in your data file:
function changeFont(obj, over)
{
obj.style.fontWeight = over ? 'bold' : 'normal';
obj.style.fontSize = over ? '13px' : '12px'; // You can not use this line
}
var tmenuItems = [
["<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Security</div>","", "", "", "", "", "", "", "", ],
["<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Ease of Access</div>","", "", "", "", "", "", "", "", ],
["|<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Internet Options</div>","", "", "", "", "", "", "", "", ],
["|<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Windows Firewall</div>","", "", "", "", "", "", "", "", ],
["<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Network and Internet</div>","", "", "", "", "", "", "", "", ],
];
Please, notice also that you should add this function every time whenyou change your menu in Deluxe Tuner application, as Tuner deletesthis function.

Q: Comprehensive Mental Health has a site license to \use JavaScript Tree Menu. We are currentlyrunning version 2.0.
Unless we set the topdy parameter to be -65, our submenus do not appear adjacent to the toplevel menu. Below are our parameters and our menu. What is causing this problem?
A: It is possible that you have some problems with your css.
The problem is that the script 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:absolute"). 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 <DIV id=SiteMenu>
to the
style="position:absolute;"
So, you'll have:
<DIV id=SiteMenu style="position:absolute;">
Check that.
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>.
