How to find Array length inside the Handlebar templates?
My Bad....
{{array.length}}
actually worked inside the template. Should have checked/tested it before posting it here.
In this case you need to reference the parent variable of the each from within the each block:
{{#each array}} {{../array.length}}{{/each}}
I think your variable being named "array" is probably conflating the issue as well. Let's assume some different JSON just to clarify:
var json = { "fruit":["apple","orange","banana"]};
So then doing this:
<ul> {{#each fruit}} <li>{{this}} {{@index}} {{../fruit.length}}</li> {{/each}}</ul>
Would yield:
<ul> <li>apple 0 3</li> <li>orange 1 3</li> <li>banana 2 3</li></ul>
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}}
