bindAsEventListener() - is there an equivalent in jQuery?

[greenie2600]

Hi all -

I've played around with jQuery, and I've been very impressed. However,
I sorely miss Prototype's bindAsEventListener() when working with
jQuery.

Has anyone discovered a comparable function in jQuery? Prototype is
great, but I'd like to at least give jQuery a shot...

Hi greenie2600,

You should go in a JQUERY forum to have this answer !
I'm not sure you will have a response in this groups.

AAMOF, jQuery doesn't have pre-baked binding. They ask their users to
understand the costs and dynamics of binding, and the concept of lexical
closure, so they "manually bind."

When it comes right down to it, I doubt the OP actually needs
@bindAsEventListener@, which is quite seldom useful. They probably use
it in a way where @bind@ is sufficient (i.e. without pre-filled
arguments to be passed after the event object).

If you aren't passing arguments to bindAsEventListener like,

Grid ={
otherMethod: function() {
//...
},
handler: function(arg1, arg2, arg3) {
this.otherMethod(arg2)
//...
}
};

$(document.body).observe('click',
Grid.handler.bindAsEventListener(Grid, "edit", "admin"));
// --> when document.body is clicked it will call the handler method
bound to Grid,
// so "this" is Grid, and pass the event object as arg1, "edit" as
arg2, and "admin" as arg3.

If your code looks like:
$(document.body).observe('click',
Grid.handler.bindAsEventListener(Grid));
// then you can totally use "bind" instead of "bindAsEventListener".

By default, in Prototype 1.6+ and jQuery, "this" of an event handler
is the element that you are observing.
In my previous examples it would be document.body. However using bind
I made "this" reference the Grid object.

AFAIK There isn't an equiv in jQuery, but then again the need is
pretty edge case.
