javascript - 此表的 jQuery 插件/库可简化代码

Question

https://jsfiddle.net/51Le6o06/48/

请查看 jsfiddle，代码变得复杂，我的功能无法正常工作。

谁能告诉我我可以使用什么来代替标准的 jQuery 和 javascript 来使它更容易构建(使用显示更多样式的分页方法)。

我需要在 jsfiddle 中对现有 html 进行排序、过滤和分页。

谢谢。

$(document).ready(function() {
    $('.filter-gift').each(filterItems);
});

function filterItems(e) {
    var items = [];
    var table = '';
    tableId = $(this).parent().parent().attr('tag')

      var listItems = "";
        listItems += "<option value=''> -Select- </option>";
        $('div[tag="' + tableId + '"] table.internalActivities .information').each(function (i) {
            var itm = $(this)[0].innerText;
            if ($.inArray(itm, items) == -1) {
                items.push($(this)[0].innerText);
                listItems += "<option value='" + i + "'>" + $(this)[0].innerText + "</option>";
            }
        });

    $('div[tag="' + tableId+ '"] .filter-gift').html(listItems);

    $('.filter-gift').change(function () {
    if($(this).val()!= "") {
        var tableIdC = $(this).parent().parent().attr('tag');

        var text = $('div[tag="' + tableIdC + '"] select option:selected')[0].text.replace(/(\r\n|\n|\r| |)/gm, "");;
            $('div[tag="' + tableIdC + '"] .product-information-row').each(function (i) {
                if ($(this).text().replace(/(\r\n|\n|\r| |)/gm, "") == text) {

}

当涉及到具有所有过滤、排序、分页功能等的表格时，最好的解决方案是唯一的。

jQuery Datatables

只需查看链接，它很简单且高度可定制。
