How to access the added fields infos from the nested:fieldAdded event?

$("form").live("nested:fieldAdded", function(event) {
        console.log(event.type);
        console.log(event.field);
        console.log(event.data);
});

event.data and event.field are undefined...

event.field was undefined because I was using the rubygems code. The master branch version insted has the event.field object. Sorry about that! I will submit a pull request for documenting this as soon as I can.

I'd really appreciate some documentation here, because I can't seem to get it working. oll-g's code won't even trigger an alert for me.

I found I've had to change the code in jquery_nested_form.js from:

$(link).closest("form").trigger({ type: 'nested:fieldRemoved', field: field });

to:

$(link).closest("form").trigger('nested:fieldRemoved', { field: field });

It looks like the efvent wasn't being triggered, I'm guessing that in newer versions of jQuery ryan's using of the 'type' field is no longer supported.

FYI: It seems to work as advertised to me without any changes, assuming event.data is OK as undefined.

@virtualfunction the latest jquery version supports this style of event triggering (see "Alternative way to pass data through an event object" example in the documetation)

$(document).on("nested:fieldAdded", ".my_selector", function() {
   alert("Field added!");
});

@iwan Could you please make a pull request with this example?
