$(document).ready(function(){

});

$.test = function(){

var form = "<form id='test_jquery'><select class='select' name='select2'></select></form>";

var $form = $(form);

$('body').append($form);

var option = [

['Not select 1', 'test', true],

['Select', 'new', false],

['Not select 2', 'test2', false],

];

var $option = $('<option>');

for(i in option){

var $elem = $option.clone(true);

$elem.text(option[i][0]);

$elem.val(option[i][1]);

$elem.addClass(option[i][1]);

if(option[i][2] == true){

$elem.attr('selected', true);

}

if there append all works

$form.find('.select').prepend($elem);

}

var test1 = $('#test_jquery .select2 option:selected').val() == 'test'; true all browsers

$('#test_jquery .select2 .new').attr('selected', true);

test2 = $('#test_jquery .select2 option:selected').val() == 'new' && $('#test_jquery .select2 option:selected').length == 1; //true all browsers but opera false
