angularjs - Angular.js selecting from a hash / object -

i have simple dropdown:

{{x}} <select ng-model="x" ng-options="k k in [1,2,3]"></select>

easy: {{x}} replaced selected value 1, 2 or 3.

but if info looks this?

<select ng-model="x" ng-options="k.a k in [{a:1},{a:2},{a:3}]">

i want ones, twos , threes depending on selection "{a:1}".

hm.. this suggests maybe won't want. ideas?

you're missing 1 piece.

if @ docs ng-options, there several forms comprehension look can take.

the form have label value in array. form, when take options, gives entire value of array item, in case {a: 1}.

one of other forms can utilize select label value in array. stick look in from, , result of that look bound model.

so like:

ng-options="k.a k.a k in [...]"

then you'll value of a attribute of selected array item.

here's fiddle you.
