Question

我对ReactJS很新，并且已经学习了不到两个月，我试图重新创建我在网上看到的一个项目，并将其更新为ES6 https://github.com/perborgen/YourSecondReactProject/blob/master/finished_project.html。

问题是，我以前从未尝试过任何调用，比如Ajax，fetch等。所以当我开始这个时，我得到一个错误，我的ajax是未定义的，我很确定我可能有我的语法或格式错误，请帮助我并解释我的错误是什么以及如何解决它们。非常感谢你！

P.S。我没有iTunes帐户，所以我使用了Tmdb api。

这是我试图做的事情

要使用ajax功能，您需要安装jquery。你可以运行

npm install -S jquery

安装它。之后，您需要在组件中导入它，如

import $ from 'jquery';

然后修改你的ajax调用，如

search = (URL) => {
    $.ajax({
        type: "GET",
        dataType: 'jsonp',
        url: URL,
        success: function(response){
            this.showResults(response);
        }.bind(this);
    });
}

然而，更好地利用其他库（如axios或node-fetch）专门用于进行API调用而不是使用Jquery，因为除了AJAX调用之外，它还具有更多功能你不需要。

从文档中获取的Axios get请求示例为

// Make a request for a user with a given ID 
axios.get('/user?ID=12345')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

Ajax调用ES6;得到un-def错误
