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: How to modify data.js in deluxe menu to change the font color if the user click on css pull down menu.
Expl. If the user click on 'Webdesign' and then on 'Thema Webdesign' the color dosn't change to #333. So the user don't now, where is it. Please test it on www.media-design.ch. Thank!
A: Javascript/DHTML Tree doesn't save a presseditem as it saves a tree state. It works within 1 page only and if youreload the page you should set a pressed item using Javascript API:
function dtreet_ext_setPressedItem (menuInd, itemID)
<script type="text/javascript">
var i = <?php echo $selitem; ?>;
onload=setPressed;
function setPressed()
{
dtreet_ext_setPressedItem(0,dtreet_ext_getItemIDByIndex(0, i));
}
</script>
You should define selitem using server side script.
Q: How can I remove the vertical lines that connect the + signs in my javascript slide out menu. I do want to keep the -+ signs but just not the virticle lines.
A: See the following javascript slide out menu parameters:
// Lines
var tpoints = 1;
var tpointsImage = "vpoint.gif";
var tpointsVImage = "hpoint.gif";
var tpointsCImage = "cpoint.gif";
If you don't want to use lines you should set:
// Lines
var tpoints = 0;
var tpointsImage = "";
var tpointsVImage = "";
var tpointsCImage = "";
Q: Is it possible via code customization to remove the border only forthe top level of js dropdown menu?
A: You can use Individual Item Style in that case.
You should create Individual Style, for example:
var itemStyles = [
["itemBorderStyle=none,none"], // style 0
];
And assign it for top items:
var menuItems = [
["Home","testlink.html", "", "", "", "", "0", "", "", "", "", ], // assign style 0
["Product Info","", "", "", "", "", "0", "", "", "", "", ], // assign style 0
["|Features","testlink.html", "", "", "", "", "", "", "", "", "", ],
["|Installation","", "", "", "", "", "", "", "", "", "", ],
["|Supported Browsers","", "", "", "", "", "", "", "", "", "", ],
["||Windows OS","", "", "", "", "", "", "", "", "", "", ],
["||Internet Explorer","", "", "", "", "", "", "", "", "", "", ],
["||Firefox","", "", "", "", "", "", "", "", "", "", ],
["Samples","", "", "", "", "", "0", "", "", "", "", ], // assign style 0
["|Sample 1","testlink.html", "", "", "", "", "", "", "", "", "", ],
["|Sample 2 is Disabled","testlink.html", "", "", "", "_", "", "", "", "", "", ],
["Contact Us","testlink.htm", "", "", "", "", "0", "", "", "", "", ], // assign style 0
];
