Recent Questions Treelist Devexpress On Javascript
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: How do you configure settings so that on default a specific "Tab" is always set to on or shown as the preselected Tab in the javascript tab menu,I have a eStore page where I would like to insure that a specific Tab isalways shown on default and all others are hidden on the first revealingof the page?
Can you help?
A: Use he following parameters to set the selected top and submenu items:
var bselectedItem = 0;
var bselectedSmItem = 0;
Deluxe Tabs doesn't support API functions which can return theselected tab aslo.
You can set "bselectedItem" and " var bselectedSmItem" parametersbased on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parametersfrom your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=<?php echo $seltabs; ?>;
var bselectedSmItem=<?php echo $selsmtabs; ?>;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT>
</TD>
You should define seltabs and selsmtabs using server side script.
You can also set it on every page before you call data.js file, forexample:
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem=4;
var bselectedSmItem=3;
</script>
<SCRIPT src="data.js" type=text/javascript></SCRIPT> </TD>
Q: Is it possible to have the AJAX menu aligned vertical instead of horizontal? And is the number of levels limited? (I have a site that requires up to 4 levels...)
A: Yes, you can create vertical menu using AJAX feature.
There is no such limitation.
See the following parameter:
var dmAJAXCount=0;
That variable set the maximal number of submenus that will be loadedfrom server on your page.
Q: Do you have it in vertical orientation for dropdown menu javascript, please?
A: To create vertical drop down menu you should set the followingparameter:
var isHorizontal=0;
