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

You can define simple helper to handle it:

Handlebars.registerHelper('get_length', function (obj) {
 return obj.length;
});   

And then use it in your template eg:

{{get_length some_object}}
