Recent Questions Javascript Treemap
Q: We are registered users of the JavaScript Tree Menu software. Today I tried to use the Javascript API, but there is something I do not understand and want to ask for support.
First, I set up a very simple menu:
var menuItems=[
['Menu 1'],
['|Submenu 1'],
['Menu 2'],
['|Submenu 2'],
];
This menu is built via dm_init().
Then, I inspect the menu (in Firebug):
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
Ok, there are three submenus. Now I am going to delete one of them:
>>> dm_ext_deleteItem(0, 0, 1)
"Menu 2" disappears on the screen, this works as expected. But now when I re-inspect the menu using the API, I find that the API reports exactly the same as before:
>>> dm_ext_getSubmenuParams(0, 0)
["dm0m0", 2, "", 0, 1]
>>> dm_ext_getSubmenuParams(0, 1)
["dm0m1", 1, "dm0m0i0", 1, 0]
>>> dm_ext_getSubmenuParams(0, 2)
["dm0m2", 1, "dm0m0i1", 1, 0]
So, it seems the report function continues to know about the original menu structure and reflects it. Am I using the API in a wrong way?
The problem I want to solve is to remove the entire menu dinamico dhtml, in order to rebuild it dynamically. Because I did not see a function aimed to this functionality, my plan was to delete all main menu entries subsequently until the main menu inspector no longer reports an entry. Is there (a better) way to achieve this?
A: Unfortunately, dm_ext_deleteItem() only change visibility of theseitems.
It doesn't delete them completely.
We'll try to fix it in the next versions of JavaScript Tree Menu.
Q: In the drop down menu generator there's no option for turning the cursor into a hand. There's hourglass etc but no hand. Is there a way to make it a hand?
A: You should set the following parameter
var itemCursor="pointer";
Q: I am setting a menu up for popupMode=1 and adding the javascript to respond to the onContextMenu action. When it pops up I am having to immediately move the mouse over the menu to keep it visible. Is there any way to keep the menu from doing this?
A: You can try to play with these parameters:
var smShowPause=200;
var smHidePause=1000;
Q: I have generated my navigation menu bar and want to incorporate it into my current website.
How do I resize and position the navigational menu inside a table?
A: 1) Resize:
You could specify exact width for menu using that parameter:
var menuWidth="400px";
You can also set exact width for each top item using Individual Item Styles:
var itemStyles = [ ["itemWidth=120px"],];
var menuItems = [ ["Item 1","", "", "", "", "", "0", "", "", ],
["Item 2","", "", "", "", "", "0", "", "", ],
["Item 3","", "", "", "", "", "0", "", "", ],
["Item 4","", "", "", "", "", "0", "", "", ],
["Item 5","", "", "", "", "", "0", "", "", ],
];
2) Position the navigational menu inside a table:
You can paste the menu inside the <div> or <table> tag, for example:
<DIV align=center>
<SCRIPT src="data/data.js" type=text/javascript>
</SCRIPT>
</DIV>
<table width=800>
<tr>
<td align=center width=600><script type="text/javascript" src="data/data.js"></script></td>
</tr>
</table>
