Question

我在访问值时遇到困难，因为其键的名称中包含正斜杠。

这里是Import.io返回的JSON的摘录：

rowwise

这是我用来访问数据的jQuery代码：

cat

由于斜杠，以下一点给我带来了问题：

"results":[  
  {  
     "superawesome_link":"https://medium.com/@sprawsmdoo",
     "graf_image":"https://cdn-images-1.medium.com/fit/t/800/240/1*YIWxXylsoUQIDfQK353YuA.png",
     "avatar_link":"https://medium.com/@sprawsmdoo",
     "darken_link/_text":"Jan 28",
     "readmore_number":10.0,
     "readmore_number/_source":"10",
     "readingtime_value_numbers/_source":"7",
     "readmore_link":"https://medium.com/@sprawsmdoo/pricing-design-services-bca1c6955b47?source=latest---------1",
     "readingtime_value_numbers":7.0,
     "readmore_link/_text":"Read more…",
     "darken_link":"https://medium.com/@sprawsmdoo/pricing-design-services-bca1c6955b47?source=latest---------1",
     "postarticle_link/_text":"Pricing design servicesWhat we’re doing, how we’re doing it, and what we’re struggling with when it…",
     "readingtime_value":"7 min read",
     "postarticle_link":"https://medium.com/@sprawsmdoo/pricing-design-services-bca1c6955b47?source=latest---------1",
     "superawesome_link/_text":"Superawesome"
  },
...

错误消息是＆＃34;未捕获的ReferenceError：文本未定义＆＃34;。

如何引用var mediumJSON = "URLHERE"; $.ajax({ url: mediumJSON, crossDomain: true, dataType: 'json', success: function(response) { $.each(response.results, function(index, value) { var newPost = $("#postTemplate").clone(); newPost.appendTo('.posts'); newPost.removeAttr('id'); newPost.find('.post-title a').attr('href', value.readmore_link).text(value.postarticle_link/text); newPost.find('.post-length').text(value.readingtime_value); newPost.show(); return index < 4; }); }, error: function(jqXHR, textStatus, errorThrown) { $('.posts').html('<article class="post"><div class="quiet">There was an error fetching posts, you can read our blog <a href="https://medium.com/@sprawsmdoo">directly on Medium</a>.</div></article>'); } });以获取其价值？

Answer 1

您需要使用Bracket notation，它允许访问包含特殊字符的属性。

＆＃13;

var data = {          
     "readmore_number":10.0,
     "readmore_number/_source":"10",
     "superawesome_link/_text":"Superawesome"
  }

alert(data['superawesome_link/_text'])

＆＃13;

Answer 2

好像你使用了import.io的“Magic”。您可以简单地使用他们的App并构建一个新的Extractor。这样你就可以指出＆amp;单击所需的数据，更改数据类型（链接或文本），并为结果数据列指定所需的名称（不带斜杠）。

使用jQuery读取Import.io生成的JSON（访问名称中带有斜杠的键）
