I would like to share a modification to bindAsEventListener() that might be useful to some of you. It makes it possible to do function show(event, number) { alert(Event.element(event).id + " = " + number); } Event.observe("el1", "click", show.bindAsEventListener(this, 5); Event.observe("el2", "click",...

...his 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 handle to properly dispose of them, like this: this.mouseOver_Listener = this.highight.bindAsEventListener(this); Event.observe(this, "mouseover", this.mouseOver_Listener); ...now this will work... Event.stopObserving(this, "mouseover", this.mouseOver_Listener); ________________________________ From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane...

...leter to show the options immediately when the field gets focus. Right now at least one character must be typed for autocomplete to kick in. http://dev.rubyonrails.org/ticket/5435 I have also made some code changes directly in the script Event.observe(this.element, "blur", this.onBlur.bindAsEventListener(this)); Event.observe(this.element, "keypress", this.onKeyPress.bindAsEventListener(this)); Event.observe(this.element, "focus", this.onKeyPress.bindAsEventListener(this)); The last line is what I have added. And then I have commented some code: onObserverEvent: function()...

I am wondering if someone can explain what bindAsEventListener is used for and some common uses that I would use it for.

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 capturing keyboard events before, so I''m hoping I''m ju...

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(); Object.extend(SuperEvent.prototype, { initialize: function (event) { for (attr in event) { this[attr]...

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() {

I''ve been using the bindAsEventListener function and registering various events I want to monitor and have had some problems which might be of interest. First I have been having a crash on Safari 2.0 and 2.0.1. The logical place to call Event.stopObserving to de-register the listener is actually within the listener once it ha...

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

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

Avoiding real work I decided to try and clean up my html and remove my inline onclick handlers for Ajax.Updater calls. Here''s the inline method I''ve been using: http://hank.org/demos/ajax-inline.html Now, here''s using <script> sections to apply the behavior. http://hank.org/demos/ajax.html (firefox only) Since the links (tabs) are inside the

...owser Javascript control that enhances the HTML text input element in order to accept only digits (more or less). Supposing that ''domText'' is the DOM element corresponding to the HTML text input, we wrote the following: Event.observe(domText, "keypress", this.onKeyPress.bindAsEventListener(this)); where this.onKeyPress = function(evt) { var evtc = evt.keyCode; // char code for IE and Opera if (evtc == 0 || evtc == null) { // Firefox evtc = evt.charCode; } if (evtc >= 48 && evtc <= 57) { // Digit return tr...

...totype Event.observe. All links with the class "dropdown" should be observed for onmouseover events and execute the function showSubnavi(this) - the ''this'' argument shouldn''t be lost and i think thats the tricky part. Im sure the soultion includes something with bindAsEventListener, but I didn''t really get that.

One of the Mozilla developer released a new extension to detect JS memory leaks: https://addons.mozilla.org/firefox/2490/ If it''s accurate, it might be bad news for Prototype. I have some code using prototype 1.4 with no leaks, but other code with 1.5 leaks on every single bindAsEventListener call, and a bunch of other places. Not sure if it''s just me; I may just be using it incorrectly on the one project. But, I can''t see anything at first glance to indicate that. Just downloaded the newer version of the plugin, so I''ll do some more digging. Anyone e...

...working to tell firefox not to follow the link ----------------------------------- I have also tried using an anomyomous function within Event.observe and just to ease my brain, i tried this: $$(''a.popout'').each( function(s) { Event.observe( s, ''click'', popout.bindAsEventListener(s) ) } ); which shouldnt be any different to a standard event.observe, and isn''t! thanks for reading, any insights would be much appreciated. The reason im doing it this way and not in the html : < a href="somelink.php" class="popup" onclick="popup(); retu...

anyone have any information on how to effectively use this? Event.observe() doesn''t return anything, and nothing I''ve tried is actually removing the event listeners from the objects. -Jeremy -- Jeremy Kitchen ++ kitchen-RA8HwDor7flnDGu+y90WmgC/G2K4zDHf@public.gmane.org In the beginning was The Word and The Word was Content-type: text/plain -- The Word of Bob.
