[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.

How do I extract it like text ? Calling the .text() method, as
expected doesn't return what I need - DoSomething(this);

[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.

[jQuery] Get the onclick method of an element
Let's say you have a :
asd
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: 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.

[jQuery] Intercept javascript event
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.
