ENG: I've addapted a JavaScript serialize function by Kevin van Zonneveld to jQuery. Function works like the same named function in PHP. Be free to use it in your projects. It is especially needed when you want to post Object in AJAX (in jQuery "$.ajax()").
RUS: Я адаптировал JavaScript serialize функцию, написанную Kevin van Zonneveld, для использования с jQuery. Serialize работает также как и одноименная функция в PHP. Она хорошо выручит Вас, если Вы захотите передать в AJAX запросе Объект (JavaScript object).

Example of using: $.serialize({data: 'value'});

Source code:

jQuery.extend({
serialize: function( mixed_value ) {

// % note: We feel the main purpose of this function should be to ease the transport of data between php & js
// % note: Aiming for PHP-compatibility, we have to translate objects to arrays
// * example 1: serialize(['Kevin', 'van', 'Zonneveld']);
// * returns 1: 'a:3:{i:0;s:5:"Kevin";i:1;s:3:"van";i:2;s:9:"Zonneveld";}'
// * example 2: serialize({firstName: 'Kevin', midName: 'van', surName: 'Zonneveld'});
// * returns 2: 'a:3:{s:9:"firstName";s:5:"Kevin";s:7:"midName";s:3:"van";s:7:"surName";s:9:"Zonneveld";}'
