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: I created a custom error page for a site, but the menu would not display.
I found that this was due to the erroneous "current directory" in the bad link test, for a non-existent directory.
which is: level2/level3/
I changed the script code from:
<script type="text/javascript"> var dmWorkPath = "DMworkfiles/";</script>
<script type="text/javascript" src="DMworkfiles/dmenu.js"></script>
to:
<script type="text/javascript"> var dmWorkPath = "DMworkfiles/";</script>
<script type="text/javascript" src="/DMworkfiles/dmenu.js"></script>
adding the "/" before "DMworkfiles/dmenu.js" source reference allowed the .js file to be found in the root directory and the menu would display.
The problem is that the little menu "expansion" arrow .gif cannot be found in the "current working directory" of level2/level3/. just little "blanks" show.
I tried changing:
var dmWorkPath = "DMworkfiles/";
to:
var dmWorkPath = "/DMworkfiles/";
but that did not enable the display of the arrows.
I also had to prefix all of the links in the menu with a "/" to indicate the root directory because of the "current directory" for the bad page.
I hope I have explained the problem sufficiently.
What am I doing wrong or missing here?
A: You can use additional parameters to make menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.
For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters
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: I\'m testing out your menu system and I have a question regarding one of our current menu item\'s functionality.
Currently, I have a menu item that performs an onclick window.open function so that it opens a popup window at a certain size and with certain parameters.
Is it possible to have similar functionality with an item on your menu system?
A: You should use a Javascript code with a link field so:
["Text", "javascript:window.open('../Help/Text_Index.htm', 'Help', 'height=450,width=600,scrollbars');"]
