我正在使用此页面http://loudev.com/中的 jQuery MultiSelect - 视觉上一切正常，但我需要按照选择它们的顺序输出数据。

本文在此处发布了一个解决方法jquery multiselect selected data order，但我是一个完全的初学者，需要一些帮助来实施该解决方案。

理想情况下，我想在文本字段中输出所选项目。任何帮助深表感谢。

    $(function(){
        $('#keep-order').multiSelect({
          afterSelect: function(value, text){
            var get_val = $("#multiple_value").val();
            var hidden_val = (get_val != "") ? get_val+"," : get_val;
            $("#multiple_value").val(hidden_val+""+value);

这些值存储在 Keeporder 数组中，因此您需要在 PHP 代码中获取 keeporder 数组

$hidden=array();
$hidden = $_POST['keeporder']; //get the values from the keeporder
print_r($hidden);
