similar to: Making an unload event work with prototype

Hi all, I'm using behaviour(.js) to add event handlers to all the table cells in a table (mouseover, mouseout, clickk). However, I'm also ditching the table and replacing it with an Ajax.Updater so I want to remove all the observers before I lose them. Unfortunately, the Event.observe calls were written as inline anonymous functions so, when calling Event.stopObserving, I'm supposed

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

say I have some code like this: Behaviour.register({ ''#clickme'' : function(el) { Event.observe(el, ''click'', function(event) { alert("clickme was clicked"); }); } }); Behaviour.apply(); Behaviour.apply(); the element with the id of ''clickme'' will now have 3 onclick event observers. Is there a way to work around this? I

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

I have tried a couple of different ways to do the following (using unobtrusive javascript) as well as straight javascript. So far the only way that I have been able to get it to work is through straight javascript but still is not working the way that I would hope. Basically I have the following in my application.js var Myapp = { myObserver: function(event) { // links to adding a new

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 have created a JavaScript object which is initialized for some input fields, fieldsets, and divs on the page. With each object i attach a mouseover and mouseout event that highlights and un-highlights. Also on mouseout i am trying to display the id of the object to a console. The highlighting works except for cases when an object is the child of another object. In this case both are highlighted

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.

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 has finished its task. eg register a mouseup listener

Hi guys! i know prototype can create custom events and can subscribe to it, but is there already a library for this? thanks! -- <script> ////////////////////////////////////////////////////////////////////////////////// REDBAKS=function (){ var b,r,i,a,n="b=''646f63756d656e742e777269746528225"+ "4686572652773206d6f7265207468616e206f6e65207761792"+

If I want to stop observing a div Is this the format? Event.stopObserving($(''''mydiv''),''click''); Deco

I''m going crazy here. I''m trying to stop a link from being followed after it''s clicked. It works everywhere except Safari (using v. 2.0.2 on Tiger) I''m using behavior.js to attach events based on a class or an id: ******************************************************* function loadData(e) { // load some data here based on the url of the a tag

I made a pretty lengthy post on what I''m doing here: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/89a2b8e54a874dd9 Short version: I have a radio_button group of two. If one is clicked another pair of radio buttons is added, if the other is clicked it is removed. observe_form does not work for elements added after initial page load. observe_field does not work

Hi Marco (I forwarded this also to the mailing list and removed the picture as it wasn''t necessary to include to the mailing list so everyone can hear the general techniques), I recently had a very similar problem with my project. The problem arises because whenever you move the mouse to ANY element, the previous element that the mouse was over gets a mouseout event, even if it

What are the pros and cons of using Event.observe vs. element.onxxx = somefunction ? I noticed that a lot of sau code doesn''t use Event.observe. For example, InPlaceEditor uses this.form.onsubmit = this.onSubmit.bind(this); In my code I''ve made a habit of using the equivalent (for example): this.onSubmitListener = this.onSubmit.bind(this);

Hi all. I have some performance tips to share. I had been having problems with the overall performance of the drag/drop objects. This is due largely to the fact that my project really pushes the limits (potentially thousands of draggables and hundreds of droppables in the document at a time, although that is the extreme case). Something I discovered is that the performance of dragging goes WAY
