Variations of using .data() in Jquery

Question

Would you please tell me, in how many ways jquery's .data() can be used.

$("element").data('field','value');

or

$("element").data({'field':'value', 'f2': 'v2' });

is there any other way, we can accompany more data like an array or something?

Answer 1

You can store any object your like even functions. For an array:

$('element').data('field', [ 'elem1', 'elem2' ]);

or

$('element').data({ someArray: [ 'elem1', 'elem2' ] });

Answer 2

var _fn=function TestFunction(){};
var _obj={};
var _arr=[];
jQuery('elm').data('function',_fn);
jQuery('elm').data('object',_obj);
jQuery('elm').data('array',_arr);
