Recent Questions Jquery Tree Js As A Menu
Q: I would like to add the javascript API to a link contained in my website that will have the corresponding item in the deluxe-tree menu act as if it was "clicked".
Presumably I need to add the script (for example) <A HREF="http://deluxe-menu.com/features-info.html" TARGET="_self" "..javascriptHere ..">. Can you give me an example please of what code goes into there.
I presume I use dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion) but where do I get the ????Ind data from and make the javascript call in the above link.
A copy of a working example together with where to get the data , perhaps on your own web pages, would help.
A: Javascript/DHTML Tree 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 dtreet_ext_setPressedItem (menuInd, itemID)
<script type="text/javascript">
var i = <?php echo $selitem; ?>;
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
</script>
You should define selitem using server side script.
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 am using deluxe-menu for the third time to create a school web site. It has worked fine on the previous two sites, but I am making a horizontal menu this time instead of a vertical menu. The menu won't align itself correctly in Firefox. I read the post in your FAQ and I set the align tag in the TD element and also the size attribute, but that didn't work.
Could you give me some suggestions. It looks fine ie IE, but not Firefox.
A: Try to specify exact value for menu width.
For example:
var menuWidth="800px";
It's necessary to specify exact value for Mozilla browsers. It helpsto position menus correctly.
Q: I need current page highlighted on javascripts tab menu.
what I do the change on data.js file.
A: Deluxe Tabs doesn't support API functions which can return theselected tab aslo.
You can set "bselectedItem" and " var bselectedSmItem" parametersbased on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
