Recent Questions Javascript Complex Tree View
Q: I'm experimenting with the purchased Treemenu. Looks very nice!
A question: When I set the menu width to 200px and the text of the item exceeds this width, text is not wrapped resulting in some strange display. How can I wrap the text in the java menu tree?
I can not simply use extra <br> tags because the data of the items are dynamic (php + MySQL).
A: You should set the following parameter
var tnoWrap=0;
Try that.
Q: Would it be possible at some point to introduce more font decoration options to the mouseover variables, I would like to add bold as a mouseover font decoration, but obviously this is not possible at the moment.
A: Unfortunately, JavaScript Tree Menu doesn't have such a feature. You can onlyset it's color. You cannot set the font of menu item bold when selected.
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 menuItems = [
["<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>","", "", "", "", "", "", "", "", ],
["<div onMouseOver='changeFont(this, 1)' onMouseOut='changeFont(this, 0)'>Hardware</div>","", "", "", "", "", "", "", "", ],
Q: My name is Wayne Dekmar, I am a registered user. I have a question when using your javascript browser menu with Frames. In the Item Parameter box, Link, I would select the page that I want open. Target, would I select custom then add below : Target='main'. Is this correct? Can you give me an example of how to do this.
A: You can set target parameter for all items:
var itemTarget="main";
Where main - is the name of the frame where you want to open the link.
or for each item individually:
["Home","testlink.html", "", "", "", "main", "", "", "", "", "", ],
Q: I have started using your menu and when testing in both IE-browsers the CPU jumps to 100% for at least 30 to 60sec.
Then the sub menu appears but also not as fast as in Firefox(no effects).
Now does my menu contains about 1476 item-lines, and I use the cross-frame modus.
Any ideas?
A: 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 Tree Menu works fast, but 1500 is a large value.
I tried to create large menus on my machine: P4 3GHz, 512RAM WinXP SP2
It takes:
- 1000 items ~ 10 sec
- 2000 items ~ 40 sec
You can try to use AJAX-like technology.
