handlebars.js “each” loop inside another “each” loop 3

Question

Suppose I want to build a dynamic table. How do I run each inside each. If the only varible that represents current item is this.

   {{#each by_widt         


        

Answer 1

You can use ../ to access the parent in a Handlebars template:

{{#each by_width}}
    {{#each by_height}}
       w: {{../this}}
       h: {{this}}
    {{/each}}
{{/each}}

That of course assumes that by_height is inside each element of by_width, if they're both at the top level then you'd need another ../:

{{#each by_width}}
    {{#each ../by_height}}
       w: {{../this}}
       h: {{this}}
    {{/each}}
{{/each}}
