Q: How do I go about using the menu javascripts feature and javascript popup on the same HTML page? I'm getting a Java Error.
A: 1) Notice that you should call dmWorkPath parameter and dmenu.js file only once on yourhtml page.
2) When you have several menus on the same page they have different menuInd (0,1,2,3...)
For example you have:
<script type="text/javascript" src="data.js"></script> //standard menu menuInd=0
...
<script type="text/javascript" src="popup-data.js"></script> //popup menu menuInd=1
You should call your popup in the following way:
<img src="mypic.gif" onClick="return dm_popup(1, 1000, event);">
or
<script type="text/javascript" src="popup-data.js"> </script> //popup menu menuInd=0
...
<script type="text/javascript" src="data.js"></script> //standard menu menuInd=1
You should call your popup in the following way:
<img src="mypic.gif" onClick="return dm_popup(0, 1000, event);">
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 was looking for a feature to reverse the order of items added dynamically to the drop down html menu
I'm not sure where to find it or how to go about getting this new feature incorporated into my code.
Could you please help me and tell me where to go next?
A: To add your items dynamically in the specific position you should usethe following function:
dm_ext_addItemPos(mInd, smInd, iParamsArr, Pos)
where Pos - the position in the menu where you want to add new item(starts with 0).
Check that you have dmenu_dyn.js file in the same folder with dmenu.js
file and set
var dynamic=1;
parameter.
