如何添加分页来过滤产品页面（使用 jQuery 和 PHP）

Question

当我尝试在每页最多 5 个产品的限制下添加分页时，它只显示 5 个产品但下一页和上一页不起作用。 我认为 jQuery 脚本正在崩溃。 如何为此添加分页。

我正在使用这个脚本：

$(document).ready(function(){

    filter_data();

    function filter_data()
    {
        $('.filter_data').html('<div id="loading" style="" ></div>');
        var action = 'fetch_data';
        var minimum_price = $('#hidden_minimum_price').val();
        var maximum_price = $('#hidden_maximum_price').val();
        var brand = get_filter('brand');
        var ram = get_filter('ram');
        var storage = get_filter('storage');
        $.ajax({
            url:"fetch_data.php",
            method:"POST",
            data:{action:action, minimum_price:minimum_price, maximum_price:maximum_price, brand:brand, ram:ram, storage:storage},
            success:function(data){
                $('.filter_data').html(data);
            }
        });
    }

    function get_filter(class_name)
    {
        var filter = [];
        $('.'+class_name+':checked').each(function(){
            filter.push($(this).val());
        });
        return filter;
    }

    $('.common_selector').click(function(){
        filter_data();
    });

    $('#price_range').slider({
        range:true,
        min:1000,
        max:65000,
        values:[1000, 65000],
        step:500,
        stop:function(event, ui)
        {
            $('#price_show').html(ui.values[0] + ' - ' + ui.values[1]);
            $('#hidden_minimum_price').val(ui.values[0]);
            $('#hidden_maximum_price').val(ui.values[1]);
            filter_data();
        }
    });

});

在 fetch_data 页面中，我将结果作为echo $output传递给索引页面。

在这里检查我使用 Bootstrap 和 Jquery 创建的这个分页也许它会帮助你。

但是对于您的问题，最好创建一个 SandBox 或 JsFiddle 这样我可以帮助您。

 // https://reqres.in/api/users $(document).ready(function (){ var users = { content: $('#tableContent'), pagination: $('ul.pagination'), currentPage: 1, maxPage: null, init: function () { const self = this; this.fetchData(); this.pagination.on('click','li', function () { self.handlePagination($(this).data('page')); }) }, fetchData: function () { const self = this; return $.ajax({ url: "https://reqres.in/api/users?per_page=3&page=" + self.currentPage, type: "GET", beforeSend: function () { self.showToDom(`<p>Loading ...</p>`) }, success: function(response){ // update maxPage self.maxPage = response.total_pages; const Template = self.createFragment(response); self.showToDom(Template); } }); }, showToDom: function (dom) { this.content.empty().append(dom); }, handlePagination: function (info) { if ( info === "next" ) { this.handleNext(); } else if ( info === "prev" ) { this.handlePrev(); } else { this.handlePage(info); } }, handleNext: function () { this.currentPage++; if ( this.currentPage > this.maxPage ) this.currentPage = this.maxPage; this.fetchData(); }, handlePrev: function (){ this.currentPage--; if ( this.currentPage <= 0 ) this.currentPage = 0; this.fetchData(); }, handlePage: function (num) { this.currentPage = num; this.fetchData() }, createFragment: function (res) { console.log('pagination response', res); let body = ``; res.data.forEach(function (item) { body += ` <tr> <th scope="row"> <img src=${item.avatar}> </th> <td>${item.first_name}</td> <td>${item.last_name}</td> <td>${item.email}</td> </tr> `; }) return body; } }; // init the Object users.init(); })

 .content { display: block; min-height: 500px; } .navigation { width: 100%; } img { width:40px; height: 40px; }
