Recent Questions Navigation Tree Ajax
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 have a popup that in one of the submenus has an input field.
There is a problem – if the user clicks into the entry field,
but moves the mouse outside the php dhtml menu,
the menu can close while the user is still typing.
Is there any way to prevent that from happening?
A: You can make submenus to stay visible till you click outside the menu or scroll your page.
To enable this feature you should set the following parameter:
var smHidePause=-1;
Q: I need to set individual itemtargets for a number of items in the navigation bar menu...
A: You can set target parameter for all items:
var itemTarget="_blank";
or
var itemTarget="main";
where main - is the name of the main frame where you want to open the link
or for each item individually:
["Home","testlink.html", "", "", "", "_blank", "", "", "", "", "", ],
...
["Home","testlink.html", "", "", "", "main", "", "", "", "", "", ],
Q: I am really interested in this product but I am having difficulty adding content to the java menu bar tabs. I checked the FAQ section and followed the directions, but when I test it nothing happens and I get an error on page at the bottom.
A: See, for each item you should assign the ID property of the contentDIV (see data file with your menu parameters). You should set var tabMode=0;
["Style Name","contentName", "", "", "", "", "1", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Style Description","contentDescription", "", "", "", "", "", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Style Variations","contentVariations", "", "", "", "", "", "", "", ],
["-","", "", "", "", "", "0", "", "", ],
["Empty","", "", "", "", "", "2", "", "", ],
And on your html page you should create DIV's with such ID. You canset background image for these DIV's in styles.
<div id="contentName" style="height: 0%; visibility: hidden; background-image: url('img/back.jpg'); background-repeat:repeat-y;" class="tabPage">
<br><br><br>
<p align=center><img src="img/style01_title.gif" width=140 height=90 alt="Glass Style Tabs"></p>
<br><br><br>
You should paste your content here!!!!!
</div>
<div id="contentDescription" style="height: 0%; visibility: hidden;" class="tabPage">
<br><br><br>
<p align=center><img src="img/style01_title.gif" width=140 height=90 alt="Glass Style Tabs"></p>
