Recent Questions Javascript Tree Loop
Q: I am working with tabs. Can you tell me why I would be receiving the following menu javascript error:
‘tabs[...].id’ is null or not an object
A: Try to set the following menu javascript parameter:
var bselectedSmItem=0;
Q: Is there a way to have the menu stay expanded in the same exact state when
I click on a menu item of the javascript tree view and go to a new page?
A: There is no need to write additional code on a server side to remember what items were expanded/collapsed.
DHTML Tree Menu can save items state automatically.
Please, see the example of the menu that works with cookies:
http://dhtml-menu.com/tree-examples/tree-menuxp-save-state.html
Set the following parameter:
var tsaveState = 1;
and the menu remembers its structure for each user who visit your page.
Try to expand/collapse items. Then reload the page and you'll see results.
Q: Is there a way we can add javascript behaviors to the popup menu in java actions? For example, is there a way we can add an onClick function to a popup menu in java item (eg, onClick="return MyFunction( )" ) so that we can catch and process key events?
I'm really hoping there's a way of doing this...
A: Unfortunately, you can't assign onmouseover/onClick/onContextMenu event to each item. However, you can achieve this by using standard html objects within popup menu in java items, for example:
var menuitems = [
["<div onContextMenu='your_code_here'>item text</div>", ""]
];
You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
Q: I would love to buy your product BUT, I am not sure if it will do what I want - can I call javascript within the dynamic menu?
For example my old page for disaster recovery we have inserted a URL substitution :
The javascript function is called at the top of the nav page:
<script LANGUAGE = "JavaScript" SRC = "../urlSub.js"> </script>
then the link on the nav menu
<a> href="#" ONCLICK = "urlSubstitution('transco/sheet.asp?stype=1')">Table of Contents </a>
-----------------------------------------------------------------------------------------------------
HOWEVER, Im not sure if this is possible with your product?
A: Yes, it is possible.
Actually you can use your own Javascript code instead standard links and html code inside item text. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
or
var menuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
