Iterate through keys / values ​​in Hogan.js

Is there a way to iterate over keys and values ​​in an object using Hogan.js? I cannot find such documented functionality - only iteration over arrays seems to be documented. Is it even possible to iterate through objects in hogan.js (or any other mustache.js implementation)?

It is not possible to directly iterate over the keys and values ​​in an object in Hogan.js, what sub_stantial does is very important to iterate over the array.

Depending on what you want to do, you need a little prerender code. Suppose you have an object o which is equal to { k1: "v1", k2: "v2" }

. And you want your rendered template to be k1 has value v1; k2 has value v2;

, you only need this (_ is underscore ):

var oAsList = [];
_.each(_.keys(oAsList), function (k) {
  oAsList.push({ key: k, value: o[k] });


And the Mustache pattern that does the trick is {{#oAsList}} {{key}} has value {{value}}; {{/oAsList}}



I was in the same situation yesterday and after some research with Hogan.js

and Mustache.js

I found this solution:

var data = { 'list' : [{ 'name' : 'dhg'}, {'name' : 'abc'}] };
var template = Hogan.compile("{{#list}} {{name}} {{/list}}");
var output = template.render(data);
