Q: I am having some difficulty dynamically adding items to a tree javascript and menu.
I have a menu with one "root" item. I see the use of the "+" symbol within the item name. I do not see any documentation regarding this symbol, only "|". Can you explain?
If I have one menu with this one "root" node, how would I add an subitem to this root node?
Here is my code so far, but the inserted items appear to be at the same level as the root node.
var rootItem = dtreet_ext_getItemIDByIndex ( 0,0 );
var menuItem = new Array(10);
for ( var i = 0; i < producers.length; i++ )
{
var producer = producers[ i ];
menuItem[0] = producer.name;
dtreet_ext_insertItem ( 0, 0, i + 1, menuItem );
A: See dtreet_ext_insertItem () function has the following parameters:
function dtreet_ext_insertItem (menuInd, parentItemID, itemInd, itemParams)
Creates a new item and inserts it into a specified position.
menuInd - index of a javascript and menu on a page, >= 0.
parentItemID - ID property of an item.<, >= 0.
itemInd - index of a new item within the javascript and menu, >= 0.
itemParams - item parameters.
Notice that parentItemID is the Id property of the parent item (notindex). If you want to add top items you should set parentItemID=0.
itemInd - you should use this parameter if you want to add item in thespecific place, for example set itemInd=5 if you want to add itembefore the existing item with itemInd=5.
If you set itemInd=null the new item will be added at the end of this submenu and its index will be added automatically.
Q: The problem with the old computer (by clicking an item the wrong subitem appears and the windows disappears not fast enough. I have tried your recommendation
var smShowPause=200;
var smHidePause=1000;
var transDuration=350;
var transDuration2=200;
A: Try to decrease these parameters, for example
var smShowPause=200;
var smHidePause=300;
Try that.
Q: Can I show / hide the javascript floating menu as needed.
A: You should paste javascript code into item's link field of the floating menu,for example:
var menuItems =
[ ["text", "javascript:document.getElementById('dm0m0').style.visibility='hidden'", ...]
];
Q: When I select something from one of the mouseover menus it takes me to a link on a website,
is it possible to run a javascript instead?
A: Actually you can use your own Javascript code instead standard links and html code inside item text.
For example:
var bmenuItems = [
["text", "javascript:your_code_here"]
];
or
var bmenuitems = [
["<div onClick='urlSubstitution(\'transco/sheet.asp?stype=1\')'>Table of Contents</div>", ""]
];
