Overwritten binded events when use .data() with object

[Xelat]

jQuery method .data() returns object with properties "events" and "handle", which used as I understand for handling events. But when I use .data() with first parameter as object with key/values pairs, it overwrite existing data instead of adding that key/value pairs to data object. Finally when handling events of that object, I have error in Firebug console "e is undefined".

For example: $('td:first').click(someFunc).data({some_id: 11}); when click TD, will have error

Please, move ticket to jQuery 1.4.2 bugs list.

Your usage of .data() here appears to be incorrect. You're setting an object to be added to .data() on the event handler using .data(X) rather than .data(X,Y) for the key-value pairs.

I've written a number of tests here which you can review for correct usage where adding an object (or string value) in the way originally desired (that works). This all works fine using FireFox with Firebug for console output.

In particular I would direct you to review here where you can set /*Store object as a part of the event handler*/ $("td:first").click(someFunc).data('myObject', {some_id: 11}); var test2 = $("td:first").click(someFunc).data('myObject'); console.log(test2);
