Mustache.js - JSON items not rendering

This is my first look at mustache.js in anticipation of using it for a larger project.

The problem I have is the spreadsheet JSON output I plan to use on my larger project doesn't have a name for the array. So based on the tutorial I followed on Lynda.com, ideally my array data would be called "fruits" but as you can see from my JSON data below, it outputs with no name for the array, just [].

https://api.myjson.com/bins/czrxt

https://docs.google.com/spreadsheets/d/1KIg84G9CXErw2bWhkEHWUkOI4CR-biFeLqCtdypaLU8/edit?usp=sharing

How can I render my set of data in mustache.js if there is no array name that can be used to output the template?

I see three issues in your code:

  1. The href in your template should be href="{{{wiki}}}". Note that the 3 curly brackets prevent the forward slashes and other special characters in the URL from being encoded (e.g. "/" -> "%2f").
  2. The src parameter in the template should be src="{{{image}}}"
  3. As mentioned previously, pass {fruits:data} as the second parameter to the Mustache.to_html function.

The revised code is:

<head>

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<meta name="description" content="">
<meta name="author" content="">
