similar to: prototype.js: enumerable mixin for hash broken

This might seem like a really daft question, but I couldn''t find an answer anywhere. How do you add something to an enumerable object? Something like var first = $A(getElementsByTagName(''td'')); var second = $A(getElementsByTagName(''tr'')); first.PUSH(second); where the PUSH is something unknown. am i supposed to use inject here in some way? Andreas

Hi and sorry if this has already been discussed. I''m new on theese lists, and I couldn''t find a way to search through them. I have been looking at the sources of script.aculo.us and I''m rather impressed by the Enumerable class. What I don''t get is why you choose to extend Array.prototype with this addon. It seems like a rather intrusive thing to do, if the code

Hi List! I am using the latest version of prototype.js from the SVN, including the wonderful $$ operator to loop through a number of elements with a certain classname. In Firefox everything works fine, no JS error, but in IE I get an error in the .each function saying that an Object was expected. What I do is function initializePlugins() { $$(".plugin").each(function(plugin) {

Hi everybody, Could somebody have a look at a little sortable example at http://www.weisshuhn.de/diagnose/sortable.html It implements two Sortables and a Draggable. You can drag elements from the "source" Sortable to the main Sortable, sort them (surprise) and drag them to a trash. Whenever you drag from the "source", a new element is created (by cloning an invisible

Hi all, I encountered a big problem when trying to use Scriptaculous and Htmlarea in the same page. The Htmlarea code uses a lot of "for (var i in array_variable)" to iterate on array elements. Problem is that prototype.js augments Array.prototype, which then show up in the iteration, severely breaking htmlarea. The easy workaround is for sure to use "for (var i = 0; i <

I was wondering whether anybody could please tell me why this is causing an error in IE (works in Firefox): $A(container.getElementsByTagName(''*'')).each( function(el) { Element.cleanWhitespace(el); }.bind(this)); What would be an alternative of achieving the same?

Hey guys, I recently published an article documenting some of the more useful and interesting parts of Prototype''s Enumerable, Hash and Array objects. You can find it here: http://encytemedia.com/blog/articles/ 2005/12/07/prototype-meets-ruby-a-look-at-enumerable-array-and-hash If you have any feedback or suggestions, fire away. Cheers, -Justin Palmer

Hi, I''m new to this mailing list, so first off, a big THANK YOU for the script.aculo.us and prototype.js libraries. I''m trying to integrate script.aculo.us into an existing pretty large Javascript codebase (see http://openrecord.org). I''m running into a problem with prototype.js and the existing codebase''s use of for/in loops over an Array.

I am using Prototype 1.6.0.2 on Firefox 3.0b4. The following does not work when I enter it in Firebug: $A([1,2,3,4]).each(function(n) {alert(n);}); The above is just an example. Any array, using $A and any enumerable method, returns the following: TypeError: iterator.bind is not a function Seems like some objects are not being extended correctly? Using Prototype 1.5.0 on Firefox 3.0b4, this

I have been reading the documentation at: http://www.sergiopereira.com/articles/prototype.js.html One of the examples does this: var someNodeList = $(''lstEmployees'').getElementsByTagName(''option''); var nodes = $A(someNodeList); nodes.each(function(node){ alert(node.nodeName + '': '' + node.innerHTML); }); How can I access the array index as

It seems to me that Validations are quite useful for many objects, even ones having nothing to do with ActiveRecord. Common examples are Contact Us forms, multi-step forms, web service paramater validations, etc. I took a look at the source for Validations, and it seems that it is very independent from ActiveRecord. I caught only three depenedencies: 1. validates_numericy --> depends on

I''m trying to debug an a uncaught exception: Permission denied to get property Object.constructor error. I have some code like this: myObject.js ------------ function myObject (arg1, arg2, arg3) { //does some constructor related stuff } myObject.prototype.createSomething = function() { // do more boring stuff // return an Array; } manager.js ----------- var fakeHashMap = new

Hey all, I have two models in my rails project that share a lot of traits. They each have the same 4 properties, and now I need to add 2-3 methods to each one that will be the same. In the spirit of DRY I am looking for a solution to write these methods only once. Both of these models already inherit from ActiveRecord . . . and I didn''t know if it was safe to just "whip up" a

can you please tell me why this is not working? i got the example for how to use each online and copied it to a t (except i added the if). its telling me items.each does not exist. var items = document.getElementsByClassName(''editView''); if (items.length > 0){ items.each(function (result){ thisid = result.id; thiskey = thisid.replace(/se_item_/gi, '''');

Hey folks I am just investigating using Aspects for logging my main Javascript "interfaces". I don''t believe Prototype has any built in capabilities for this but I just thought I''d check and see how people had tackled this before. I am still getting to grips with core JS so apologies if this is easy or obvious.. I am Googling as we speak also.. Cheers Matt

Hi folks, Can anyone share some accumulated wisdom about the best way to spec mixins in general, and (Jamis Buck-style) ActiveRecord "concerns" in particular? The standard situation here is that there''s a bunch of functionality, related by concept if not by implementation, that one wants to inherit in many different classes (e.g. ActiveRecord models) without having to

Can anyone recommend good books, online tutorials, or any other learning materials for Javascript - specifically Object Oriented Programming using JS? I want the rest of my dev team to be able to help me code in JS, specifically using prototype and scriptaculous. I''ve been using JS for so long, and I kinda "grew up" on OOP programming but my whole team is Coldfusion

Hi everybody- First time poster, please be gentle. I have written a little rails app where you can create divs and move them around via Thomas'' wonderful dragdrop.js. I would like to be able to fire an AJAX event to update the top and left of the dragged object upon release. I see many AJAX link_to_remote and observe_field. What is the proper way to observe that the position (not

is there a way to take advantage of prototypes Event.pointerX when using Behaviour to manage my events? somthing like.. var myrules = { ''body'' : function(el){ el.onclick = function(){ alert(Event.pointerX(e)); } } }; thanks ______________________________________________________________________ Alex Duffield .

Hi, Has anyone seen any documentation on the Hash Object defined in the prototype library? To be precise the following methods - 1. keys 2. values 3. toQueryString 4. inspect 5. Merge I am trying to play around with them and have come up with the following examples - var h = $H({name: "john doe", email: "john-Ch9RrZxMC0c@public.gmane.org", msg: "say hello to
