如何在HTML中使用JSON数据

Question

I have json with js file list.js and I am trying to get the data from it in HTML file index.html .Tell me please how to connect it with HTML.

Here's my json with js file:

 $(function () {

      var categories = {
        menu: [{
          title: "animals",
          children: [{
            title: "insects",
            children: [{
              title: "ant",
              title: "bee",
              title: "fly"
            }]
          },
          {
            title: "mammals",
            children: [{
              title: "bear",
              title: "platypus",
              title: "tiger"
            }]

          },
          {
            title: "reptiles",
            children: [{
              title: "crocodile",
              title: "turtle"
            }]
          }
          ]
        },
        {

          title: "fruits",
          children: [{
            title: "apple",
            title: "pineapple",
            title: "pear"
          }]

        },
        {
          title: "vegetables",
          children: [{
            title: "potato",
            title: "tomato",
            title: "carrot"
          }]
        }]
      };
      var getMenuItem = function (itemData) {
        var item = $("<li>")
          .append(
          $("<a>", {
            html: itemData.title
          }));
        if (itemData.children) {
          var childrenList = $("<ul>");
          $.each(itemData.children, function () {
            childrenList.append(getMenuItem(this));
          });
          item.append(childrenList);
        }
        return item;
      };

      var $menu = $("#menu");
      $.each(categories.menu, function () {
        $menu.append(
          getMenuItem(this)
        );
      });
      $menu.menu();
});

The idea is to make unfolding menu to show these types Animals-Insects-ant,fly,bee;Mammals-bear,platypus,tiger;Reptiles-crocodile,turtle;.Please help, I am new to this field.:(

This post explains very well you you can combine an external JSON file with an html file: How to read an external local JSON file in Javascript

However! What you are having is not an json file. What i would suggest is getting your JSON data, store it within its own file and use the .json extension and then follow the example shown in the post
