Oct 21, 2010the below code is for a form that is validated against some external (valid.js) functions. It's my first forray into Event Delegation and stupidly (testing in FF only just now) I didn't realise that the addEventListener isn't recognised in IE. Anyone got an idea which way I should look at sorting it. I am still searching and playing around but can't seem to find the right solution.

JQuery :: Replacing HTML And Firing Same Selector/Event?
Oct 14, 2010I'm having a problem that I can boil down to this example.
HTML
<div id="test_div">
<a href="#" class="test_link">test</a>
</div>
[Code].....
The first time I click the link, it fires and I get an alert. The second time, after I replaced the HTML contents of the DIV, it won't fire again.
why the function isn't being triggered even though I'm swapping the same content in?

Nov 11, 2011I'm trying to load some html content into a page via the ajax .load() method (wrapped within the $(document).ready() function).After I execute this, I'd like to bind all new span elements from the loaded content to a context menu plugin like this:
$("#selector").contextMenu({
menu: ''myMenu''
},

Unfortunately since the span elements are coming from the ajax request,I don't think I can bind a normal event handler as per the plugin. [URL] how to use event bubbling in this situation.
Prototype __proto__ Super And Delegation
Oct 30, 2007One thing I haven't figured out about javascript is the treatment of
__proto__.
Inheritence, whether prototypes or class-based, is just a shorthand
form of delegation (leaving aside dynamic dispatch).
In Java a derived class serves as a wrapper for its superclass. The
derived class can easily access members of its super class using the
nice "super" keyword. Why, in javascript, is this functionality buried
in the unofficial "__proto__" property? It seems that it must have
been the intent of the language designer that explicitly accessing the
prototype chain is a bad thing for some reason, although I can't see
any reason.
By googling, you can find a lot of weird hacks to add "super"-like
functionality to javascript, although many of them look misguided to
me. It certainly seems that this is a commonly confusing part of the
language.
If __proto__ were an official part of the language, implementing a
decorator or proxy pattern would be nicely simplified compared to
class-based inheritence. The "before-and-after" style of AOP (which is
just another style of shorthand for delegation) would be possible
without any crazy tricks.
So, anyone care to set me straight? Why isn't __proto__ or something
like it a well defined part of javascript? Shouldn't it be?

JQuery :: Use $ In A Quoted Selector?
Jun 12, 2009I have a UL list with hyperlinks in the LIs. When I click on the hyperlink, I want to go up the list, and get the html() within the first LI in the list. I have a ('a') click function that returns the hyperlink as $(this).
Now how do I get up to UL and down to LI? (It's actually more complicated because I really want to go up to a top level UL and down to a top level LI...but let's start here).
When I start with $(this) how can I integrate it into a selector? For example, I can supposedly do ("LI > UL > LI:first"), but can I do ("$(this) > LI > UL > LI :first") or do I do ($(this) "> LI > UL > LI:first") ?

View 4 Replies View RelatedJQuery :: Selector To Handle Each DIV Among Many - With The Same ID
Jul 2, 2010I was developing a very simple application, just for training some Ajax. It works like that:
» I make a search using Ajax and it gives me a list with a lot of cities according to their state;
» After receiving the data, I can only manipulate the first DIV (that contains the city data).
The problem is that the city boxes (DIVs) has the same ID and, when the jQuery function is set (to send the address to an input that will make a search through Google Maps API), it only works for the first DIV. Then, if I search new cities, it works, but the same manner :(
Check out the screenshots:
