So, I found that array elements can be accessed in Handlebars using:
{{myArray.2.nestedObject}} and {{myArray.0.nestedObject}}
..to get the third and first elements for instance. (handlebars-access-array-item)
Is there a way to get the last element from an array? I tried creating a helper for it:
Handlebars.registerHelper("lastElement", function(array) {
return array.last(); //Array.prototype extension
});
...and calling it as follows in the template:
{{lastElement myArray}} or even {{lastElement myArray.lastElement nestedArray}}
Sadly, this doesn't work. Helper functions return strings apparently. What I need is a way to be able to do this even with multi-dimensional arrays.
Should work, I've tested it.
Template:
{{last foo}}
Data:
{foo : [1,2,3,4,5,6]}
Helper:
Handlebars.registerHelper("last", function(array) {
return array[array.length-1];
});
