Q: I have been evaluating your dhtml-tree product, for a potential use.
It does just about every thing I want apart from 1 thing:
I want each css dropdown menu item to (optionally) support the following syntax:
<a href="menu_link.html" onClick="return fnClickedLinked()">Menu Link</a>
I have worked out how to change the "menu_link.html", and also that it could be something like "javascript:fnClickedLinked()".
However I want the above syntax, where search engines can pick up the link and if my function returns false, the link is not followed when clicked.
Is this possible?
Or can I cancel the link navigation using the tree API node click event??
A: Actually you can add the html code inside item's text:
["|<a href="menu_link.html" onClick="return fnClickedLinked()">Menu Link</a>","", "", "", "", "Tip", "", "", "", "", ],
You can also try to use API function:
function dtreet_ext_userClick (itemID)
http://deluxe-tree.com/functions-info.htmlQ: I know. I have two menus on the page and I am not using beforeItemImage orafterItemImage for the top menu in javascript (the one you referenced below), but I need it for the second menu. The parameters for that menu are in mainnav_data.js.
Even when I only call dmWorkPath and dmenu.js once, it does not work.
A: See, it is not correctly to use image-based items:
["","", "mainnav_data.files/corpinfo.gif", "mainnav_data.files/corpinfo2.gif", "", "_self", "0", "", "", "", "", ],
and specify beforeItemImage/afterItemImage parameters. They won't work in that case.
You can create such buttons in the following ways:
1) Use image-based menu (images with text).
Create normal and mouse-over state images (with text) for each item:
["","", "mainnav_data.files/corpinfo.gif", "mainnav_data.files/corpinfo2.gif", "", "_self", "", "", "", "", "", ],
["","", "mainnav_data.files/new.gif", "mainnav_data.files/new2.gif", "", "_self", "", "", "", "", "", ],
["","", "mainnav_data.files/xxxxx.gif", "mainnav_data.files/xxxxx2.gif", "", "_self", "", "", "", "", "", ],
2) Use combined background for the menu in javascript items (images without text).
var beforeItemImage = [,]; //left-side image for normal and mouse over state
var itemBackImage = [,]; //background or image for normal and mouse over state
var afterItemImage = [,]; //right-side image for normal and mouse over state
var beforeItemImageW = '';
var afterItemImageW = '';
var beforeItemImageH = '';
var afterItemImageH ='';
But you should create a small images in any Graph Editor, for example:
button_n_back.gif
button_n_left.gif
button_n_right.gif
button_o_back.gif
button_o_left.gif
button_o_right.gif
You cannot use these two methods together!Q: Is there any way to keep a menu lit up when going to another page? Or do the menus always have to default back to their normal state?
I want the menu to know what page the user is on and keep that section highlighted. Any ideas?
A: You should set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem.
You can't get this ID after you reload your page. That is why you should write your own code on PHP.
Q: Now, one more little question -
in a Tree menu, I know how to make a menu expand by default and expand only on a mouse click.
However, I believe there is a way to make a menu item expand on a "mouse over" without a click.
How can this be done?
A: No, unfortunately it is not possible to expand the tree menu onmouseover now. It is possible that we'll add this feature in the nextversion.
