[jQuery] Alert on click of class alerts n amount of times (n = amount of same class in doc).

[jQuery] Alert on click of class alerts n amount of times (n = amount of same class in doc).


I'm listening to some generated elements in an iframe. These elements
are given the class 'wp_sl'. I need to, when an element with this
class is clicked, do some work with it. However, say I have generated
3 elements with the class 'wp_sl':
----
el_1, el_2, el_3
----
Using the code below, if I click on the first element, I will be given
an alert 3 times. If I click on the second, 2 times. And on the third,
I will be alerted 1 time.
I'm unsure why this is happening, because I can do the same outside of
an iframe, and it works perfectly - only alerting for the element I
click on.
Code:
[code]
var my_frame = jQuery('#content_ifr').contents();
        jQuery('.wp_sl', my_frame).click( function() { alert("hi") });
[/code]
