Recent Questions Javascript Tree Graph
Q: I'm using the deluxe-tree; my dynamic tree menu is very long; and the page has a vertical scroll bar as a result. My question is, does the dynamic tree menu support anchors? So let's say I do mypage.aspx#mynode, and mynode is a tree-node, and happens to be on the bottom of the page, can we make it so that the user goes to that node, without him using the vertical scroll bar?
A: No, it is not possible.
But you can collapse your tree menu by default:
var texpanded=0;
and use API functions to expand the specific items based on the page you are now:
<script>
dtreet_ext_expandItem (dtreet_ext_getItemIDByIndex (0, 0), 1);
dtreet_ext_setPressedItem (0, dtreet_ext_getItemIDByIndex (0, 1));
</script>
See more info about API functions here:

Q: Is there a way we can add javascript behaviors to the sliding dhtml menu actions?
For example, is there a way we can add an onClick function to a menu item
(eg,onClick="return MyFunction( )" ) so that we can catch and process key events?
A: Unfortunately, you can't assign onmouseover/onClick/onContextMenu event to each item.
However, you can achieve this by using standard html objects within items, for example:
var menuitems = [
["item text
", ""]
];
You can use your own Javascript code instead standard links. For example:
var menuItems = [
["text", "javascript:your_code_here"]
];
Try that.Q: I set a custom target at '_mainFrame' required by Dreamweaver to view in a particular frame. When I click my button it opens in its own window.
Your thoughts would be appreciated.
A: Please, check the following code, for example
var itemTarget="_mainFrame";
["Galerie de photos","photos/index.php", "img/arrow_r.gif","img/arrow_o.gif", , "_self", , , , ],
or
["Galerie de photos","photos/index.php", "img/arrow_r.gif","img/arrow_o.gif", , "_mainFrame", , , , ],
I suppose that now you have such code
["Galerie de photos","photos/index.php", "img/arrow_r.gif","img/arrow_o.gif", , "_blank", , , , ],
Q: Hi, I purchased your deluxe-menu product and it's working great, the only problem I'm having is the tree menu in javascript is always fully expanded when a new customer enters the site. I've looked through your support blog but I can't find a reason for it.
A: Check that parameter:
var texpanded = 0;
It expands all items by default.
