[jQuery] Re: Intercept javascript event
AOP is not really the answere here. As you can see there is a callback
function - so the user presses some other buttons and then I have to
replay the initial button's onclick functions.

One idea: have a look at the Aspect Oriented Programming plugin.
Seehttp://plugins.jquery.com/project/AOP
andhttp://code.google.com/p/jquery-aop/
If this isn't exactly what you are looking for, then therin is code to
pre- and post-hook existing events.
I hope this helps.

Here's what I'm trying to do :
I have a page with some links. Most links have a function attached to
them on the onclick event.
Now, I want to set a css class to some links and then whenever one of
the links is clicked I want to execute a certain function - after it
returns , I want the link to execute the onclick functions that were
attached to it.
Is there a way to do what I want ?
Here's an attempt at an example :
$(#link).click(function1);
$(#link).click(function2);
$(#link).click(function(){
firstFunctionToBeCalled(function (){
// ok, we're inside the callback - now execute function1 and
function2
});
}); // somehow this needs to be the first one that is called
function firstFunctionToBeCalled(callback){
// here some user input is expected so function1 and function2
must not get called
callback();
}
All this is because I'm asked to put some confirmation boxes (using
boxy) for a lot of buttons and I really don't want to be going through
every button.
[jQuery] Get the onclick method of an element
Let's say you have a :
a href=# onclick='DoSomething(this);'asd/a
I want to get the onclick text in a variable - something like
var onclick = $('a').attr('onclick');
The problem is that the onclick variable now is a function and if I
try to execute , this wil be the document instead of the link .
How can I get only the text, so I can later reattach it to the link ?
[jQuery] Re: Get the onclick method of an element
Well .. that's the problem - i tried it like that and it didn't work.
When setting the attribute back on the link, the this in DoSomething
(this); is not the link, but the window.

Sorry I should have written

[jQuery] Re: Get the onclick method of an element
Perhaps then you can extract it as text like I mentioned in my first
post, then store it in a variable?
How do I extract it like text ? Calling the .text() method, as
expected doesn't return what I need - DoSomething(this);

As I am not sure what your function does or why it needs to be applied
this way, I can't solve the problem exactly - but why not just use an
event instead of an onclick in the element? That is what jQuery is
there for :-)

[jQuery] Re: Get the onclick method of an element
Damn ... I somehow thought this would be easy to achive .
The whole idea was to not change existing code
Still .. if anyone has any more ideas :). Somehow it seems that this should
be doable.

Ok, I've done some tests and here is my suggestion.
First of all, should just ask - I assume you are calling it after the
element? Probably is obvious, but thought I'd check.
Ok, here's the deal: onclick is not really an attribute but a mouse
event. Therefore jQuery will take the contents as a function and write
it out as an event. The only alternative is to insert your DoSomething
(this); into a standard attribute like title or alt and then take
it from there. This way you should be able to insert it exactly as its
written and not have it converted into an event.
Hope this will help?
