I would like to use handlebars.js or mustache.js to iterate over a list of families, and then iterate over that family\'s members. Inside of both loops, I want to display pr
Sorry I'm a little late in the game here. The accepted answer is great but I wanted to add an answer that I think is also useful, especially if you are iterating over simple row/column arrays.
When you're working with nested handlebar paths, you can use ../ to refer to the parent template context (see here for more information).
So for your example, you could do:
{{#each families}}
{{#each members}}
{{../surname}}
{{given}}
{{/each}}
{{/each}}
This was especially useful for me because I was making a grid and I wanted to give each square a class name corresponding to its row and column position. So if rows and columns, simply return arrays, I can do this:
{{#each rows}}
{{#each columns}}
{{/each}}
{{/each}}
Update
This solution is for Handlebars. A comment below explains why it will not work in Mustache.
