Recent Questions Context Menu In Treeview Javascript
Q: What I would like to see is the ability to have a base site navigation menu with all the definitional entries (size, locations, icons, etc.) defined but all the menuitems be called from an Ajax file.
A: You cannot use ajax submenus for the top items.
But you can use several .js file, for example:
params.js //file with all menu parameters (size, locations, icons, etc.)
all code before
var menuItems = [
...
];
dm_init();
data_ajax1.js //data files for ajax submenus
data_ajax2.js
data_ajax3.js
...
main_data.js - data file with the following code:
var menuItems = [
["Item 1","", "", "", "", "", "0", "0", "data_ajax1.js", "", "", ],
["Item 2","", "", "", "", "", "0", "0", "data_ajax2.js", "", "", ],
["Item 3","", "", "", "", "", "0", "0", "data_ajax3.js", "", "", ],
["Item 4","", "", "", "", "", "0", "0", "data_ajax4.js", "", "", ],
];
dm_init();
You can also place this code into your html page directly (in the place where you want tohave a menu):
<script type="text/javascript">
var menuItems = [
["Item 1","", "", "", "", "", "0", "0", "data_ajax1.js", "", "", ],
["Item 2","", "", "", "", "", "0", "0", "data_ajax2.js", "", "", ],
["Item 3","", "", "", "", "", "0", "0", "data_ajax3.js", "", "", ],
["Item 4","", "", "", "", "", "0", "0", "data_ajax4.js", "", "", ],
];
dm_init();
Q: There is one other issue I am hoping you can help with? When the dhtml web menu drops down in Safari over a SWF -- it disappears. I have added the function dm_ext_ruleObjectHide() code to the top of my data file. Can you please advise what else I can try?
A: Submenu couldn't overlap flash in Safari correctly.
And the following code:
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) &&(navigator.vendor.indexOf('Apple Computer') != -1) &&(navigator.product=='Gecko'))
return true;
in function
function dm_ext_ruleObjectHide()
{
// Safari detect
if ((parseInt(navigator.productSub)>=20020000) &&(navigator.vendor.indexOf('Apple Computer') != -1) &&(navigator.product=='Gecko'))
return true;
else
return false;
}
cause flash to disappear in Safari.
You can try to write this function in the following way:
function dm_ext_ruleObjectHide()
{
return false;
}
Q: Cross-frame mode: after clicking on a menu item and the subframe is loading and then mouse over the menu when the subframe has not finished loading a javascript error occurs and then the javascript vertical menu breaks.
A: You can get this error when you load pages from the another domain.
JavaScript Tree Menu can support this mode for the same domain only -- ifyou loaded a page to a subframe from another domain, the submenuscan't be shown in it. It happens because all browsers don't allow todo that for security reasons. Just imagine if you'll able to create aframeset from 2 frames, 1st frame will be with a zero height-width,and you'll load your page into it. Then user will go to another domainand your "invisible" frame will change a content of other pages!
Q: Is there a way to center the primary navigation and left-align the drop down for themenu script ?
A: Set the following parameters:
var itemAlignTop="center";
var itemAlign="left";
