Recent Questions Javascript Tree Paging
Q: Thank you for your prompt reply. But i was wondering where should I paste this code? Can you please explain the working of the javascript toolbar menu function
dm_ext_changeItemVisibility (menuInd, submenuInd, itemInd, visibility)
I have 5 items in the javascript toolbar menu : Admin Options, Status Report, Remarks, Edit Profile, Data Entry.
I want to disable some fields for different users.
I have 3 role id's set in my database.
I want certain fields disabled for different users.
For eg : For Roleid =1 , i.e admin , I want all items to be visible.
For Roleid =2 , i dont want the Admin Options to be visible.
For Roleid=3 , I dont want Admin Options & Status reports.
Can you please elaborate on the working of the changeItemVisibility function. I was confused as there were no examples to demonstrate the code.
A: Notice also that you should set
var dynamic=1;
parameter to use API functions.
Q: How can I use Danish characters in my menu using javascript? In normal html you would use something like this:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
What should I do in JavaScript Tree Menu?
A: You should turn on "Tools/Use utf8 encode" property.In that case your data file will be saved in UTF-8 encode. So, youshould set UTF-8 encode on your page too
<meta http-equiv="Content-Type" content="text/html"charset="UTF-8">
If you don't want to use UTF-8 encode on your page you should turn off"Tools/Use utf8 encode" property, save your data file and manuallychange your letters in any text editor.
You can also replace your letters with special sets, for example
É - Capital E, acute accent
var menuItems = [
["É....","testlink.html", "", "", "", "", "", "", "", ],
Q: The cascading javascript menu does not spans frames or windows like Applets. Is that correct?
I was not able to make the sample to do it.
A: The DHTML Menu and Java Menu are built on different technologies.Java menus can create submenus that cover frames as a standard Windowssubmenus. DHTML Menu can't do that, because it's controls is htmlobjects, they can't overlap Windows controls. So, cascading javascript menu hascross-frame ability that allows it to show submenus in differentframes. But it 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!

var menuWidth="700px";
