jQuery data() JSON Encoding issues -

in current jquery mobile application trap click events on variety of html elements, extract whole set of data-* attributes element using

var data = $(element).data(); 

package json string

var json = json.stringify(data); 

and send off elsewhere downstream processing.

the problem have run (and pretty sure has started recent versions of jquery mobile) elements such radios, checkboxes , buttons have annonymous functions part of data() array. serializing such functions is

• not relevent application
• more importantly, triggers javascript along lines of "an attempt made use object no longer valid"...

by dint of experiment have found issue anonymous functions turn in raw data() object as

1. buttonelements
2. mobile-checkboxradio

etc. build own object serialize devoid of these offending entities.

this ok have found issue. change jqm version , boom, problem crops on again since attribute name has changed (e.g. mobilecheckboxradio in place of mobile-checkboxradio).

question - suggest more generic, attribute name agnostic, way of stripping out these offensive bits? own efforts , trying figure out typeof of object attribute have failed since string. suppose check phrase "annonymous function" in string sounds clumsy.

i figured out way this. 1 can following

var data = $(element).data(); $.each(data,function(key,prop){if ('object' != typeof(prop)) /*do */)} 

here fiddle demonstrating happens radio button. note 2 of data-* attributes returned objects. 1 of them, mobilecheckboxradio anonymous function. try serialize data , exception - being trapped , reported. safely cloned object, shorn of anon function goes well.

this has benefit of being "version proof". whether better checking small handful of attributes liable cause such errors debatable.
