将 JSON 数据转换为看起来像表格的 HTML 列表

Question

有嵌套的 JSON 数组，目前正在尝试创建一个类似于表格的 HTML 列表 ul/li 类型。

这是我的 JSON 数据，问题是对象的名称。

{
  "aaData": [
    {
      "id": "1",
      "template_id": "1",
      "question": "Is government stable?",
      "answer": "Stable",
      "parent_question_id": "0",
      "section_id": "2",
      "subquestions": [
        {
          "id": "2",
          "template_id": "1",
          "question": "Is there funding approved?",
          "answer": "Since March 2013",
          "parent_question_id": "1",
          "section_id": "2",
          "subquestions": [

              "template_id": "1",
              "question": "How much funding do we have?",
              "answer": "120 Million",
              "parent_question_id": "2",
              "section_id": "1"

              "section_id": "1"
            },
            {
              "id": "6",
              "template_id": "1",
              "question": "When will the currency be paid?",
              "answer": "7 days after invoice",
              "parent_question_id": "2",
              "section_id": "1"
            },
            {
              "id": "13",
              "template_id": "1",
              "question": "why do we do this?",
              "answer": null,
              "parent_question_id": "2",
              "section_id": "1"
            }
          ]
        },
        {
          "id": "7",
          "template_id": "1",
          "question": "What groups are going to investigate?",
          "answer": null,
          "parent_question_id": "1",
          "section_id": "2",
          "subquestions": [
            {
              "id": "8",
              "template_id": "1",
              "question": "What employees have clearance to go?",
              "answer": null,
              "parent_question_id": "7",
              "section_id": "1"
            },
            {
              "id": "9",
              "template_id": "1",
              "question": "Do employees have passports?",
              "answer": null,
              "parent_question_id": "7",
              "section_id": "1",
              "subquestions": [
                {
                  "id": "10",
                  "template_id": "1",
                  "question": "Are employees able to travel?",
                  "answer": null,
                  "parent_question_id": "9",
                  "section_id": "1"
                },
                {
                  "id": "11",
                  "template_id": "1",
                  "question": "Can employees enter without VISA?",
                  "answer": null,
                  "parent_question_id": "9",
                  "section_id": "1"
                }
              ]
            }
          ]
        }
      ]
    },
    {
      "id": "12",
      "template_id": "1",
      "question": "Is market good?",
      "answer": null,
      "parent_question_id": "0",
      "section_id": "2"
    }
  ]
}

这是我的代码，我只想在行中显示问题和答案，而不是每个元素。并且还希望它看起来像一张桌子，但有正确的缩进（twitter bootstrap？）。

function buildHtml( obj , ul ) {

            for (i in obj) {

                console.log(obj[i]);
                //if(i == "question") {
                    var li = document.createElement('li');
                    li.innerHTML = obj[i];
                    li.className = "list-group-item";
                    //li.style.display = "table-cell";
                    ul.appendChild( li );
                    ul.className = "list-group";
                    //ul.style.display = "table-row";

                    if ( typeof(obj[i])== "object" ) {

                        var childUl = document.createElement('ul');
                        li.appendChild( childUl ); 

                        buildHtml(obj[i], childUl );            
                    } 
                //} 

            }


        } 
        var ul = document.createElement('ul');
        ul.className = "list-group";
        //ul.style.display = "table-row";
        buildHtml( questions ,ul );
        var div = document.getElementById('test');    
        div.appendChild( ul );

......

<div id="test"></div>

所以如果有人有想法请告诉我。

添加表格结构的外观：

Is government stable? Stable
     Is there funding approved? Since March 2013
           How much funding do we have? 120 Million
           Do we have all raw materials available? Not all, need to find correct type of wood.
           What currency is the funding in? GBP
           When will the currency be paid? 7 days after invoice
           why do we do this?
     What groups are going to investigate?
           What employees have clearance to go?
           Do employees have passports?
                Are employees able to travel?
                Can employees enter without VISA?
Is market good?

Answer 1

这是一个简单的原型函数，可以帮助您入门。

var Menu = function (data) {
    this.data = data;
};

Menu.prototype.render = function (root) {
    var ul = $("<ul></ul>");
    var li = $("<li></li>");
    li.append($("<a></a>", {
        url: this.data.id,
        text: this.data.question
    })).appendTo(ul);
    ul.appendTo(root);
    if (this.data.subquestions) {
        Menu.renderMenus(this.data.subquestions, $("<li></li>").appendTo(ul));
    }
};

Menu.renderMenus = function (menus, root) {
    $.each(menus, function (key, val) {
        var m = new Menu(val);
        m.render(root);
    });
}

Menu.renderMenus(aaData, $("#test"));

您显然可以在需要的地方向数据添加更多字段。

更新

根据您的要求，让嵌套列表可折叠，如 here 所示，我已经更新了我的原始代码，并对您引用的网站上的代码进行了一些修改。
