By default the prototype.js gives us the function /* prevent memory leaks in IE */ Event.observe(window, ''unload'', Event.unloadCache, false); But there is no unload event in out application as the content of the div keeps changing using the Ajax.Updater function. To handle such a scenario, we''ve added the following lines of code to prototype.js /* prevent

If that doesn''t work, then you''ve done something wrong somewhere. ''Cause it works for IE for me and everyone else. The only advantage I see with the YUI toolkit is that it''ll defer attaching events to elements that do not yet exist in the DOM. Big whoop, only a sloppy programmer would try to attach an event to a non-existant element. With Prototype, you can

Hello, I have a treeview, that works with scriptaculous in order to load the nodes dynamically. I also have in the main part of the page, a table with the list of elements. The lists of elements can be drag-dropped on the treeview in order to move them around (they are also draggable on other parts of the page) I need though, to refresh the treeview to reflect changes when a folder was moved

Event.observe(myelement, ''click'', myfunc.bindAsEventListener()); That might fix your wagon.

Hi Everybody, I was wondering if there is such a work done with Scriptaculous/Prototype before and if not how to achieve it? Example : http://www.anatolip.com/ It is done with codes borrowed from moofx and his own codes. Thanks in advance Danial _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org

I ran 2 tests. One using proto''s Event.observe, and another using an in-line handler of the "keydown" event in a textbox. Using .bindAsEventListener, the event.keyCode is always returning a capital letter, no matter what. The in-line event handler returns lowercase vs. uppercase correctly... What''s going on? I guess I find it hard to believe no one has tried

Hi, I have a class ''Menu'' with a method ''addItem''. The method (simplified) looks like this: addItem: function(itemId, text) { this.container.innerHTML += ''<div id="''+itemId+''">''+text+''</div>''; Event.observe(itemId, ''mouseover'',

Hi, I was reading about the Yahoo! library recently and was really excited by the idea that I wouldn''t have to branch for IE in my event handlers. Is there any chance that such abstraction will come to Prototype? Thanks, Sam

Hello, please consider the following code example. It applies the onclick handler to all image tags, and through window.event it ensures that it works in IE too: -------------------------------------------------- var imgs = $(''foo'').getElementsByTagName(''img''); for(var i=0; i<imgs.length; i++) { // Apply onclick handler imgs[i].onclick=function() {

Hey all, I working on a project, but I am not sure I can do what I want to do. The following works beautifully: Event.observe(el, ''click'', function () { this.className += " myClass"; return false; }); I have also tried doing this: this.varname = ''test''; Event.observe(el, ''click'', function () { alert (this.varname); }.bind

Had a nasty memory leak that was seriously slowing down the browser and eating up a couple megabytes every reload. I was using: $$(''.dyntable'').each(function(elm) { new DynTable(elm) }); To set up my behavior, but discovered that just running: $$(''.dyntable''); Caused the memory leak all by itself. The fix I found for it was to change Element.extend to a

Just wondering why Event.stopObserving() doesn''t remove the itself from the Event.obervers array?

Hi guys, I know this is not the perfect place to ask this question, but I''m struggling with object-oriented javascript and event-handlers and you guys are probably the only ones adept enough to help me out with this. I have this calendar code I hate (and still have to maintain ;) and wanted to change it to use object-orientation. So I have written a JavaScript-class called

I have the following code but it keeps on giving me this error when it runs. --- Error: this.alertBox has no properties What would be causing this? My Code checks out when I call this.alertBox() from the setup function it works fine but when I try and put in on an event observer it doesn''t work. What do you guys think? Thanks, Jon Code Here: var Updater =

This is obviously rough draft and not thoroughly tested, but it seems to work. If you''d like, give it a try (load it after you load prototype.js): Function.prototype.bindAsEventListener = function(object) { var __method = this; return function(event) { return __method.call(object, new SuperEvent(event || window.event)); } } var SuperEvent = Class.create();

1. Create a separate class that has your highlight/unhighlight behavior in it, and extend just the element you want to highlight with that class... like this (also allows you to easily apply this behavior elsewhere when you need it in the future): Object.extend(this.el, HighlightBehaviorClass.prototype) 2. When defining your event handlers, assign them to variables so you have a

I want to take an existing DOM object and extend it with some functionality. I know there''s a way to do this with prototype. Unfortunately, I''m not entirely sure how to do this. Basically, I want to take an existing DOM object and turn it into a ''widget'' by adding some functionality. say we have a span: <span id="blah">some text

Hello boys and girls In the ever-loving spirit of OSS, here''s another feature for s.a.u. In particular it''s called Effect.Accordion, and is a scriptaculified version of openrico''s Accordion. Work in progress, I''ll submit further modifications as the come in, but this is 90% of what needs to be done. I anticipate some bugs when I start using it more. Tested

Hi, I''ve just had my very first attempt of making a JavaScript class, "prototype" style, so please bare with me, for any disastrous errors :-) Anyway, I''ve made this class, which is called on an input field on focus: http://pastebin.com/487417 It works fine in FireFox, but causes some problems in IE. My question is regarding line 69 in the paste. What is

When I click an InPlaceEditor field in Firefox 1.0.7, the page scrolls up to the top. That''s disconcerting, and often ends up with the editable field out of the viewable pane. I can duplicate this on both Mac and PC. Is there a way to prevent this? Even the demo at http://wiki.script.aculo.us/scriptaculous/show/Ajax.InPlaceEditor does this. Jay Levitt
