Question

我已经从file_put_contents创建了文件faqs.json并得到了正确的结果（见图1）。但是，当我尝试使用“ Select2 JS”进行渲染时，它总是以“无法加载结果”结尾，我只是按照网站上的给定说明进行操作。我无法理解的一件事是如何从json文件中提取post_title和post_name。我相信我在这里缺少什么。

注意：json文件内容是从wordpress的“自定义帖子类型”中获取的

这是我的示例json文件。图1

[
    {
        "ID": 1336,
        "post_title": "test",
        "post_status": "publish",
        "post_name": "test",
        "post_excerpt": ""
    }
    {
        "ID": 1335,
        "post_title": "What are the requirements for",
        "post_status": "publish",
        "post_name": "what-are-the-requirements-for",
        "post_excerpt": ""
    }
]

这是我的JavaScript文件。图2

function formatRepo (repo) {
  if (repo.loading) return repo.text;

  var markup = '<div class="clearfix">' +
  '<div class="col-sm-1">' +
  '<img src="' + repo.owner.avatar_url + '" style="max-width: 100%" />' +
  '</div>' +
  '<div clas="col-sm-10">' +
  '<div class="clearfix">' +
  '<div class="col-sm-6">' + repo.full_name + '</div>' +
  '<div class="col-sm-3"><i class="fa fa-code-fork"></i> ' + repo.forks_count + '</div>' +
  '<div class="col-sm-2"><i class="fa fa-star"></i> ' + repo.stargazers_count + '</div>' +
  '</div>';

  if (repo.description) {
    markup += '<div>' + repo.description + '</div>';
  }

  markup += '</div></div>';

  return markup;
}

function formatRepoSelection (repo) {
  return repo.full_name || repo.text;
}

$(document).ready(function(){

  $(".js-data-example-ajax").select2({
    ajax: {
      url: $json + "faqs.json",
      dataType: 'json',
      delay: 250,
      data: function (params) {
        return {
          q: params.term, // search term
          page: params.page
        };
      },
      processResults: function (data, page) {
        // parse the results into the format expected by Select2.
        // since we are using custom formatting functions we do not need to
        // alter the remote JSON data
        return {
          results: data.items  
        };
      },
      cache: true
    },
    escapeMarkup: function (markup) { return markup; }, // let our custom formatter work
    minimumInputLength: 1,
    templateResult: formatRepo, // omitted for brevity, see the source of this page
     templateSelection: formatRepoSelection // omitted for brevity, see the source of this page  

  });
});

select2 js不显示json文件的结果
