Q: I will build menu for several books’ Contents, each book is more than 100 lines and has links. I think if all the books’ contents in 1 *.JS file then it is TOO LOONG!!.
Can I break it down to 1 book for 1*.JS ? How?
A: You cannot divide your menuItems parameter.
You can only use one .js file for your menu parameters and the other.js file for your menuItems = [...];
But you can do it in two ways.
1) You can try to use several menus on the one page, for example:
param.js // file with menu parameters (all parameters before menuItems = [...];)
menu1.js // menuItems for "AC-DC", "ANLOG"
menu2.js // menuItems for "DIGITAL", "WinXP"
menu3.js // menuItems for "MS-Word", "MS-Excel"
In these menu files you should write
menuItems = [
...
];
dm_init();
Then you should install your menu in the following way
<script type="text/javascript" src="param.js"></script>
<table>
...
<script type="text/javascript" src="menu1.js"></script>
...
<script type="text/javascript" src="menu2.js"></script>
...
<script type="text/javascript" src="menu3.js"></script>
But it will be easier to use vertical menu in such case
var isHorizontal=0;
var smColumns=1;
2) You can also try to add some code, see the attached example.
In the first file (@MY books (Multiple Col.js) I write menuItems for the first item "AC-DC".
Notice that you should delete comma at the end of the last item
var menuItems = [
["AC-DC","", , , , , , , , ],
["|@Book1","testlink.htm", , , , , , , , ],
...
["|@Book3","", , , , , , , , ],
["||CH02","", , , , , , , , ],
["||CH01","", , , , , , , , ] // delete comma at the end of the last item
];
In the second file (@MY books (1.js) you should write
menuItems = menuItems.concat(
[
["ANLOG","", , , , , , , , ],
["|@Book1","", , , , , , , , ],
["|@Book2","", , , , , , , , ],
["|@Book3","", , , , , , , , ] // delete comma at the end of the last item
]
);
In the third file (@MY books (2.js) you should write
menuItems = menuItems.concat(
[
["DIGITAL","", , , , , , , , ],
["|Item 1332","", , , , , , , , ],
["WinXP","", , , , , , , , ],
["|Item 1333","", , , , , , , , ],
["MS-Word","", , , , , , , , ],
["|Item 1334","", , , , , , , , ],
["MS-Excel","", , , , , , , , ],
["|Item 1335","", , , , , , , , ] // delete comma at the end of the last item
]
);
dm_init();
Notice that you should write dm_init(); function in the last file.
In the .html file you should write
...
<tr>
<script type="text/javascript" src="@MY books (Multiple Col.js"></script>
<script type="text/javascript" src="@MY books (1.js"></script>
<script type="text/javascript" src="@MY books (2.js"></script>
</tr>
I hope you understand me.
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.
