javascript - 使用 simplePagination.js 显示 json 数据？

Question

<强> PAGINATION DEMO

我正在使用handlebars.js 和 simplePagination.js 开发分页

1. 数据从 JSON 加载并使用handlebars.js 显示

2. 现在我必须将 JSON 数据映射到分页，在哪里进行？除此之外，官方网站上没有太多文档“http://flaviusmatis.github.io/simplePagination.js”

请求您的帮助。非常感谢任何意见/建议。

JS 代码:

$(function () {
    function loadPosts(posts) {
        $('#posts').empty();
        posts.each(function () {
            var source = $("#post-template").html();
            var template = Handlebars.compile(source);
             var context = {
            author: this.data.author, 
            domain: this.data.domain,
            id: this.data.id,
            ups: this.data.ups,
            downs: this.data.downs,
            num_comments: this.data.num_comments,
            subreddit: this.data.subreddit,
            title: this.data.title,
            url: this.data.url,
            permalink: this.data.permalink,
        };
            var html = template(context);
            $('#posts').append(html);
        });
    }
    $.ajax({
        dataType: 'json',
        url: "https://www.reddit.com/.json",
        success: function (response_json) {
           // data = $(response_json.records.page);
          data = $(response_json.data.children);
            dataCount = data.length;
            //console.log(data);
            /* if (dataCount > opts.pageMax) {
                 paginate(pageCount);
                 posts = data.slice(0, opts.pageMax);
                 console.log(posts)
             } else {
                 posts = data;
             }*/
            //loadPosts(posts);
            loadPosts(data);

            $('.pagination').pagination({
                items: dataCount, // json length count
                itemsOnPage: 4
            });
            $('.pagination').pagination('selectPage', 1);
            //$('.pagination').pagination('prevPage', dataCount);
            //$('.pagination').pagination('nextPage', dataCount);
            //$('.pagination').pagination('getPagesCount', dataCount);
            //$('.pagination').pagination('getCurrentPage', dataCount);
            $('.pagination').pagination('updateItems', dataCount);


        }
    });

});

在设置分页之前，只需隐藏其他项目items.slice(4).hide();

 $("#light-pagination").pagination({
        items: 25,
        itemsOnPage: 4,
        cssStyle: "light-theme",
        // This is the actual page changing functionality.
        onPageClick: function(pageNumber) {
          // We need to show and hide `tr`s appropriately.
          var showFrom = 4 * (pageNumber - 1);
          var showTo = showFrom + 4;

          items.hide()
            .slice(showFrom, showTo).show();
        }
      });

下面是工作示例

$(function() {
  function loadPosts(posts) {
    $('#posts').empty();
    posts.each(function() {
      var source = $("#post-template").html();
      var template = Handlebars.compile(source);
      var context = {
        author: this.data.author,
        domain: this.data.domain,
        id: this.data.id,
        ups: this.data.ups,
        downs: this.data.downs,
        num_comments: this.data.num_comments,
        subreddit: this.data.subreddit,
        title: this.data.title,
        url: this.data.url,
        permalink: this.data.permalink,
      };
      var html = template(context);
      $('#posts').append(html);
    });
  }
  $.ajax({
    dataType: 'json',
    url: "https://www.reddit.com/.json",
    success: function(response_json) {
      // data = $(response_json.records.page);
      data = $(response_json.data.children);
      dataCount = data.length;

      loadPosts(data);
      var items = $(".score-right");
      items.slice(4).hide();

      $("#light-pagination").pagination({
        items: 25,
        itemsOnPage: 4,
        cssStyle: "light-theme",


        // This is the actual page changing functionality.
        onPageClick: function(pageNumber) {
          // We need to show and hide `tr`s appropriately.
          var showFrom = 4 * (pageNumber - 1);
          var showTo = showFrom + 4;

          // We'll first hide everything...
          items.hide()
            // ... and then only show the appropriate rows.
            .slice(showFrom, showTo).show();
        }
      });


    }
  });


});

您需要隐藏初始数据
