[英]How do I access JSON objects using Handlebars.js?
I'm creating a basic web app using the Echo Nest API to get used to templating and fetching data from APIs. 我正在使用Echo Nest API创建一个基本的Web应用程序,以习惯于从API模板化和获取数据。 I was just wondering how I would access the 'artist_name' & 'title' objects inside 'song' from the JSON object and use Handlebars.js to insert this data inside my template? 我只是想知道如何从JSON对象访问“歌曲”中的“ artist_name”和“ title”对象,并使用Handlebars.js将此数据插入模板中? When I do the {{#each songs}} as I've written below, it doesn't work. 当我按照下面的说明操作{{#each songs}}时,它不起作用。
Thanks in advance! 提前致谢!
PS. PS。 Jeanie Tracy does not reflect my music taste. 珍妮·特雷西(Jeanie Tracy)没有反映我的音乐品味。 It's just the JSON object that came up when I was testing it! 测试时只是出现的JSON对象!

Your <article>
and <header>
don't have closing tags. 您的<article>
和<header>
没有结束标记。 While the HTML specifications may allow some tags to omit closing (like <td>
, afaik), and while some browsers are forgiving enough, I don't know if the Handlebars compiler is the same. 尽管HTML规范可能允许某些标记省略关闭(例如<td>
,afaik),并且尽管某些浏览器已经足够宽容,但我不知道Handlebars编译器是否相同。
Your songs
is still under response
. 您的songs
仍在response
。 I think it should be {{#each response.songs}}
. 我认为应该是{{#each response.songs}}
。 Also, I think you can go with {{ artist_name }}
too. 另外,我认为您也可以使用{{ artist_name }}
。
