Q: I need to know if it is possible to call a JavaScript function from the cool dhtml menu.
I have read the FAQ and noted where it lists that you can perform an alert call, and that worked on my end as well, but when Iattempted to call a function I created I could not get it torespond.
Is it possible to call a function from your menu?
Could Iget an example?
A: You can write your own functions within menuItems, for example:
["|Real-Time Data Query","javascript:window.open('http://www.domain.org/','_blank','height=758,width=1024,status=yes,toolbar=no,menubar=no,location=no');"
,,,'Query real time water quality data' ,'' , '', '', ,],
Q: Is there a way to programmatically specify which tab is selected in the html tabs navigation?
A: You can set "bselectedItem" and " var bselectedSmItem" parameters based on your link before you call your data file.
For example, move " var bselectedItem" and " var bselectedSmItem" parameters from your data file to your code.
<TD vAlign=top align=left>
/* Select Tab */
<script type="text/javascript" language="JavaScript1.2">
var bselectedItem= var bselectedSmItem= </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, for example:
<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: What can I do to optimize the load time for dhtml rollover
and prevent reloading it from the server with every page reload.
A: You can try to use AJAX technology.
AJAX-like technology: data for submenus can be loaded "on-the-fly" from the server.
New parameter:
var tajax = 0/1; - disables/enables AJAX-like support
Current syntax for item parameters ( var tmenuItems):
[text, link, iconNormal, iconOver, iconExpanded, tip, target, itemStyleInd, itemXPStyleInd, jsFileName]
Where jsFileName - .js filename on the server with submenu items ( var tmenuItems).
Q: I'm interesting in dhtml menue ability to display a different color word on a menu item when the site is on that selected page
A: The menu has only two states normal and mouseover. We'll try to add the pressed state in the future.
You can set a pressed item using Javascript API:
function dm_ext_setPressedItem (menuInd, submenuInd, itemInd, recursion)
Sets a current pressed item.
menuInd - index of a menu on a page, >= 0.
submenuInd - index of a submenu, >= 0.
itemInd - index of an item, >=0.
recursion = true/false - highlight parent items.
But notice, to use dm_ext_setPressedItem() you should know ID of selected item and subitem. You can't get this ID after you reload your page. That is why you should write your own code on PHP.
