Recent Questions Create Dynamic Tree Using Js
Q: Drop Down Menu could be the best solution for my website ... but Ihave one important question: I've seen, that it's possible to open the javascript change menu linked contents in the same or in a new window or in a frame ... but is it possible, too, to generate a new tab? To open a new window often is not possible, because most users have popup-blockers installed. And to open the contents in the same window drives the user away from the main page! Open a new tab seems to be less risky ... is there any solution to be used with Drop Down Menu? I tried to use "_tab" instead of "_self" or "_parent", but it did not work!
A: You should use _blank. If your browser supports tabs your link will beopened in a new tab (except IE, in IE it will be opened in a newwindow).
Q: I've been trying to get the menu item in dynamic tree menu to stay highlighted when clicked on and directed to that page.
A: Tree Menu doesn't save a presseditem as it saves a tree state.
It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function apyt_ext_setPressedItem(menuInd, itemID)
<script type="text/javascript">
var i = 4 //index of the selected item
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
To expand specific items you should use the following function:
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 11), 1);
Q: Compliments on your product, I particularly enjoy the complete set of gui and java, that allows for the quick changes.
After a couple of months of using the trial, I have now purchased it and installed the license.
My question however regards the performance of the menu. Using firebug I note that my deluxe menu .js are the performance bottlenecks, It appears as if they are not being cached and it appears that collecting them is taking longer then the other .js files. What can I do to optimize the load time of the javascript multi level menu and prevent, reloading it from the server with every page reload. The apache has set the expiry correct I believe, as I understand from the header.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: How can I use Danish characters in my menu using javascript? In normal html you would use something like this:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
What should I do in JavaScript Tree Menu?
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", "", "", "", "", "", "", "", ],
