Recent Questions Javascript Tree Table Windows Files
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.

Q: I've downloaded and installed the trial software and have built the example that came with it.
What I would like to do is make the sub items ("New Sample 1" - "New Sample 5") display when the user clicks "Sample Block 1", rather than having to click the little + sign next to it.
A: You should set the following parameter:
var texpandItemClick=1;
Try that.
Q: "Tools/Use utf8 encode" from my Deluxe Tuner is turned on (with check in it). You mean I will have to uncheck it?
No problem with my pages... it is only with the java swing drop down menu because there are words that doesn't show the correct letters / characters I am encoding both in French and Spanish pages. My boss said, it looks like a virus..(lol..)
A: You should turn on "Tools/Use utf8 encode" property.In that case your data file will be saved in UTF-8 encode. So, youshould set UTF-8 encode on your page too
<meta http-equiv="Content-Type" content="text/html"charset="UTF-8">
If you don't want to use UTF-8 encode on your page you should turn off"Tools/Use utf8 encode" property, save your data file and manuallychange your letters in any text editor.
You can also replace your letters with special sets, for example
É - Capital E, acute accent
var menuItems = [
["É....","testlink.html", "", "", "", "", "", "", "", ],

Q: First I want to thank you for the great support you provided. I have another question about the dynamic javascript tree. Is there a javascript API to fire an user click event so the browser will load proper page accordingly? I looked around the current APIs from your site and could not find one.
A: You can use dtreet_ext_userClick (itemID) function.

Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var tmenuItems = [
["text", "javascript:your_code_here"]
];
or
var tmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
