Dan Webb's Low Pro UJS extension to Prototype offers the following elegant DOM Builder:
var listItem = $li({ id : 'item-1' },
$strong("Some text")
);
// returns a node equivalent to: <li id="item-1"><strong>Some text</strong></li>
$('a_list').appendChild(listItem);
While this works like a dream for u...
I'm using the following to grab some updated HTML and insert it into a div with id "content"
var updater = new Ajax.PeriodicalUpdater('content', '/Doc?'+d.getTime(),
{
method: 'post',
frequency: 5,
});
The problem is that when the server is shut down (it's running inside of an app that is modifying and server up the data),...
Hello,
I'm wondering how can I submit a form via Ajax (using prototype framework) and display the server response in a "result" div.
The html looks like this :
<form id="myForm" action="/getResults">
[...]
<input type="submit" value="submit" />
</form>
<div id="result"></div>
I tried to attach a javascript function (which uses...
I have been looking at OpenLaszlo and observed that scripting in the client is implemented in JavaScript. Does this mean it is possible to use libraries like JQuery and PrototypeJS ?
...
Hi,
Several of my pages use both JQuery and Protoype. Since I upgraded to version 1.3 of JQuery this appears to be causing problems, because both libraries define a function named '$'.
JQuery provides a function noConflict() which relinquishes control of $ to other libraries that may be using it. So it seems like I need to go through a...
I'm trying to add a listener to DOM change events. I was hoping something as simple as 'dom:loaded' was baked into Prototype. I'm not sure of the 'Prototype-way' to handle this.
EDIT: I cannot control every case in which the DOM may be altered, so I can't get away with firing a custom event on every DOM change.

I'm using Prototype's PeriodicalUpdater to update a div with the results of an ajax call. As I understand it, the div is updated by setting its innerHTML.
The div is wrapped in a <pre> tag. In Firefox, the <pre> formatting works as expected, but in IE, the text all ends up on one line.
Here's some sample code found here which illustr...
Hy everyone,
I have the following script :
if (Object.isUndefined(Axent)) { var Axent = { } }
Axent.SelfLabeledInput = Class.create({
initialize: function() {
var labelSelector = arguments[0] || 'label';
$$(labelSelector).findAll(function(l) {return (l.readAttribute('for') !== null)}).each(function(l){
l.hide();
$(l.readAttr...
Is there a way to update information in a div of a parent page from a pop-up/"lightbox" window. I would like to create a pop up window that contains a form that updates a database (currently i am using php/mysql with prototype).
In other words...
I would like a user to be able to use a form in a popup window to update the database, and...
I've seen "RJS" and "RJS templates" mentioned in passing in blog posts and tutorials. I did a search, but I'm still unsure about it. Is it a technology specific to Rails, rather than a standard like JSON or YAML?
I understand it's used for "generating JavaScript." Does it generate generic JS or Rails-specific JS requiring the Prototype ...
Does anybody know of a method to trigger an event in Prototype, as you can with jQuery's trigger function?
I have bound an event listener using the observe method, but I would also like to be able to fire the event programatically.
Thanks in advance

I'm adapting a pretty basic js function into a class. Anyway, basically it just creates a floating container
above the main page. I'm aware it's incomplete, but I'm in the middle of typing it up, and keep getting caught out when attempting to call the close() function. Firefox returns a this.sdiv is undefined. I'm confused as to how thi...
Is there a built in method or defacto default plugin that will let you automatically assign an unique ID to an element in jQuery, or do you need to implement something like this yourself? I'm looking for the jQuery equivalent to Prototype's identify method
Here's an example. I have some HTML structure on a page that looks like this

My work in JavaScript and Ajax programming has stimulated a renewed interest in prototypal inheritance. Can anyone recommend any good books on the subject? In particular, books that deal with languages that predate JavaScript. This seems to be a very poorly documented subject matter, which is why I'm asking here.

I have an associative array (object) of the following construction
var menu = new Object('Submenu A','Submenu B','Submenu C','Submenu D');
menu['Submenu A']=new Object();
menu['Submenu A']['Option A']= 'foo blah text';
menu['Submenu A']['Option B']= 'blah more text';
menu['Submenu B']['Option A']= 'blah blah';

I'm looking for a good book (or webpage, maybe) on prototype-based OO. In particular, I'm looking for something heavy on theory. Ideally, I don't want something language-specific (and I really don't want something about Javascript, but if everybody said "just read the Self manual" that's fine).
Basically, is there a prototype-based eq...
Well I tried to figure out is this possible in any way. Here is code:
a=function(text)
{
var b=text;
if (!arguments.callee.prototype.get)
arguments.callee.prototype.get=function()
{
return b;
}
else
alert('already created!');
}
var c=new a("test"); // creates prototype instance of getter
var d=ne...
I have an iframe with a class name="blaclass".
Inside it, I have one div with no name (or id) and inside this id there is a div with class name = "classs". Inside this div, lie two images (with no class name/id).
How can I get those image.src? If there is a Prototype version even better!
PS: I cannot add class names/ids before the pag...
I'm trying to create an element dynamically using an HTML string. Here's a simple example using both prototype and DOM:
// HTML string
var s = '<li>text</li>';
// DOM
var el1 = document.createElement(s);
// prototype
var el2 = new Element(s);
$('mylist').appendChild(el1);
$('mylist').appendChild(el2);
Both approaches insert an empty ...
Hi all,
I want to render a partial depending on a selection in selection box. This looks trivial but I can't find an example.
All help is greatly appreciated.
