How to find Array length inside the Handlebar templates?

Question

I have a Handlebars template which is rendered using a json object. In this json I am sending an array. Like this:

var json = {
               \"array\":[\"abc\"         


        

Answer 1

If you are testing for an empty list in order to display content... In Ember.js which uses handlebars, you can have an else for the #each.

{{#each blah as |blah|}}

{{else}}
 //   If array is empty
{{/each}}
