如何使用 AJAX 方法将 JSON 数据从 Github Gist 存储到数组？

Question

我正在尝试将 JSON 数据存储在一个变量中，然后随机访问它。（随机超级英雄名称）

JSON 数据是 GitHub 下面的要点

https://gist.githubusercontent.com/abroroo/004fa0a28b94bc7100b4f1bf53acb69d/raw/09fd4ca4ed1ddb21010a48502cf0846a844b658c/authors.json

我正在尝试使用 ajax 方法（第一次），但我认为它不起作用。我在控制台中变得不确定。

这是我的代码：

var namesData;

function getNames() {
  return $.ajax({
    headers: {
      Accept: 'application/json'
    },
    url: 'https://gist.githubusercontent.com/abroroo/004fa0a28b94bc7100b4f1bf53acb69d/raw/09fd4ca4ed1ddb21010a48502cf0846a844b658c/authors.json',
    success: function (jsonNames) {
        namesData = JSON.parse(jsonNames);
        console.log('namesData');
        console.log(namesData);
    }
  });
}

这里是获取随机名字的函数


function getRandomName() {
  return namesData.names[
    Math.floor(Math.random() * namesData.names.length)
  ];
}
console.log(getRandomName());

感谢任何帮助！

Answer 1

我检查了你的 gist json 文件，它有语法错误。原点 json 是

[
  "names": [
    {
        "superhero":"Batman", 
        "publisher":"DC Comics", 
        "alter_ego":"Bruce Wayne",
        "first_appearance":"Detective Comics #27",
        "characters":"Bruce Wayne"
    },

array下不应该有键。所以将根数组更改为这样的字典

{
  "names": [
    {
        "superhero":"Batman", 
        "publisher":"DC Comics", 
        "alter_ego":"Bruce Wayne",
        "first_appearance":"Detective Comics #27",
        "characters":"Bruce Wayne"
    },

Answer 2

您不能将对象放入数组主体中。您可以像这样修改 json。

{ 
  "names":[
    {
        "superhero":"Batman", 
        "publisher":"DC Comics", 
        "alter_ego":"Bruce Wayne",
        "first_appearance":"Detective Comics #27",
        "characters":"Bruce Wayne"
    },
    {
        "superhero":"Superman", 
        "publisher":"DC Comics", 
        "alter_ego":"Kal-El",
        "first_appearance":"Action Comics #1",
        "characters":"Kal-El"
    },
    {
        "superhero":"Flash", 
        "publisher":"DC Comics", 
        "alter_ego":"Jay Garrick",
        "first_appearance":"Flash Comics #1",
        "characters":"Jay Garrick, Barry Allen, Wally West, Bart Allen"
    },
    {
        "superhero":"Green Lantern",

    },
    {
