Event Groups - Attaching Event Listeners With A Namespace
Dec 16, 2010The DOM Level 3 specification has a section (1.2.2.2) that talks briefly about "groups" of event listeners. What does this mean? Is this similar to attaching event listeners with a namespace, as in jQuery: "event.my_namespace"?

Sep 27, 2011I feel like I must be missing something simple but I can't put my finger on it...
I'm moderately new to JS (programmed in other languages though) and am working on a Google Maps project.
This piece of code should show an alert of the region's name when a map polygon is clicked. Instead, no matter what polygon is clicked, it only does the name for the LAST iterated placemark. code...
What am I missing? What would be a better way of handling this?
List Of Event Types For Listeners?

Objects & Event Listeners & Scope,
Aug 11, 2004Here's the situation: I have a javascript object for controlling a custom DHTML scrollbar. So that I can use more than one on a page, the event listeners need to be passed a reference to the particular instance of the object that each needs to connect to, but as I discovered the hard way, inside an event listener, 'this' returns a reference to the DOM object throwing the event, rather than to the JS object. Short of coming up with a linked list of different objects and having the event handler search through it for the right object when an event is generated, then writing a reference to that object to some global variable, is there any convenient way to tie this together? I hope I've made myself clear enough...
View 5 Replies View RelatedHandle Objects And The 'this' Keyword When Using Event Listeners?
Feb 24, 2009So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.

JavaScript Error Trying To Add Event Listeners Using DOM And AJAX
Oct 29, 2007I have PHP file called file1.php with an empty <div></div> in the middle. I've added a 'load' event listener so that on page load, it calls an AJAX function that calls file2.php. file2.php creates a table and loads it into the <div></div> in file1.php.
file2.php has <a> tags in it's <th> columns and I wish to trap when a user clicks on the column heading. The old way was to use the onclick() method but I'd rather use event listeners.
Here's my problem. I am getting "obj has no properties" when trying to add those listeners. I *think* it is because the code in file2.php isn't part of the original DOM tree for file1.php. So how can I use event listeners instead of onlclick()? I know I can add top the DOM by creating elements and appending them but that adds to the HTML code and my code is already in place via the AJAX call. What to do...? DO I just use the old passe onclick() method?

Deleting Objects (DOM Notes With Event Listeners Attached)
Jun 29, 2011I am creating JS objects that have some properties that contain DOM nodes, and some of these DOM nodes have event listeners attached to them. When I delete such objects, do I first need to remove the event listeners attached to some of the DOM nodes? And do I need to use removeChild on the DOM nodes that are properties of the object? Or does JavaScript take care of all that?

View 9 Replies View RelatedUnable To Login On First Visit / Enable This?
Jan 17, 2010I'm trying to set up a login formular with PHP and JavaScript/jQuery. Currently it sends an alert box, if some information are wrong. If correct, it refreshes the page, and everyone's happy.
However, I noticed upon the first visit, I cannot log in. Lets say I go to www.mysite.com and try to login, it displays a blank alert box, when it's suppose to display the username, that I supplied, and is wrong... however, it's blank.
BUT! If I go to another page and login with false informations, an alert box with the wrong username pops up - if I login with correct informations, it works.
How come it won't work on first visit? What am I doing wrong here? :confused: Pressing F5 won't work either - I have to manually switch to another page for it to work.
