我有选择元素的集合,当我第一次更改一个选择元素的值时,这个功能不工作,它工作第二次我改变价值,在控制台我有

jQuery代码：

$(document).ready(function () {
    var collection = $('SELEct.ddlJ');
    console.log(collection);
    for (var element in collection) {
        $(element).change(function () {

            $('SELEct.ddlJ').change(function (E) {
                $(this).parent().parent().find('td:last').prev().find('span').html(
                    $(this).parent().parent().find('SELEct.ddlJ').filter(function () {
                        return $.trim($(this).val()) == 'm';
                    }).length);

                $(this).parent().parent().find('td:last span').html(
                $(this).parent().parent().find('SELEct.ddlJ').filter(function () {
                    return $.trim($(this).val()) == 'n'; }).length);
            });
        });
    }
});
