javascript - How can I access a variable-referenced array element in Meteor spacebars? -

in spacebars template, have javascript array x , index i, eg.

template.test.helpers({     'foo': function() {         return {             x: ['aa','bb','cc'],             i: 1         }     } });

i can access fixed elements of x in template {{ x.[1] }}:

{{template name="test"}}     {{#with foo}}         {{x.[1]}}     {{/with}} {{/template}}

but {{ x.[i] }} doesn't work.

how can access x[i]? thanks!

one solution define custom helper:

template.test.helpers({     'getelement': function(a, i) {         return a[i];     } });

and in template, use:

{{ getelement x }}
