I am very new to Prototype and JavaScript, so this is prolly a no-
brainer for most of you.
Let me see if I can make sense...
On my page, there is a DIV where my ajax calls load pages. The main
page loads with a specific form loaded in the div. The user clicks a
link that calls another page
Hi All,
I have a draggable element that looks like this:
[code]
%= draggable_element issue_link_#{link.id}, :handle =
'handle', :revert = 'failure', :ghosting = 'true' %
[/code]
and a drop receiving element that looks like this:
[code]
%= drop_receiving_element parent_category_issues,
I'm having a problem where I can't access variables of the main class
from callbacks. It seems like I should have to use a keyword like
parent or something, but that didn't work. Any thoughts on this?
//Sample Code
var Controller = Class.create({
initialize: function() {

I am using Sortable with tree enabled on a list like below:
Group 1
Item 1
Item 2
Item 3
Group 2
Item 4
Here, both Groups and Items can be dragged. Additionally, Items can
be dragged into Groups (each Group contain an UL). However, I want to
prevent Groups from
Hi David,
JavaScript handles this differently from other languages you may be
familiar with. It's set by the calling code; it's not in any way
intrinsic to the function itself.
Here are a couple of links; the first is a general (and I hope
thorough) explanation of what's happening and how to
Hi Ryan,
What you'll want to do is:
1. Read up on the DOM and how to manipulate it. Most things are Nodes
or Elements (Element being a subclass of Node), and you can add and
remove Nodes and Elements at runtime via JavaScript using DOM
manipulation functions. There's also a non-standard
Hy all,
I have the following script, works perfectly in Firefox 2/3, but I’m
having a problem with IE7 on WinXP. The text in the label tags remains
visible next to each form field, and the labels within the form fields
don’t appear at first — they show up only after tabbing through them

i was realizing that i am redrawing large parts of the app anyway, so i came
up with something like

self isEditModeOnAndRest ifTrue: [ editor call: 'enterEditMode' ].
^ editor.
i am redrawing a little much currently, 33 ms respond time on
Hi,
Im making an Ajax get request in my Rails application.
This is the JS code.
function taxes() {
var id_1 = $('tax_1').value;
var url = '/taxes/tax_name/'+encodeURIComponent(id_1);
var tax_1 = new Ajax.Request(url, {
asynchronous: true, evalScripts: true,
Hi Ram,
The new operator creates a new object. You're assigning that object
to the variable tax_1, and then passing that into Element#update.
That's why you're getting [object] in your output.
Most times, you don't need to use the object you're creating. To
manipulate the results of a
Hi All,
I wondered whether anyone had experienced anything similar to this?
When I am dragging an item, sometimes the draggable sticks to the
mouse, and you have to click again to let it go, whereas other times,
it drags fine, and is released when you let go of the mouse button.
I am
What you need is to have the server side script, in this case
DeleteGroupMember.php, return a HTML fragment containing the new
list. Ajax.Updater will then automatically insert that fragment into
the element lmnt.
Prototype has very good documentation on this site:

Hey all! I'm sorry, but I've been butting up against this for a day

Basically, I'm trying to use the WebKit contenteditable attribute to

I have experienced some glitches with dragging as well, including the
one you are describing. I think it is just that, a glitch. You are
not doing anything wrong. What I suggest you to do is to look into

Hi T.J.Crowder,
thanks a lot for your reply!
you're telling me that since, in this case, im using the Ajax response
immediately to update div elements, it needs to be synchronous..
right? ill do that.
i removed the 'new' operator. But Firebug throws this error

I have various select boxes for currencies on a page. These can be
