javascript - key-value pairs in ng-options

Question

I need to use an associative array as data source for my select options using AngularJS.

Is it possible to use an array like this?

{
    "key1": "val1",
    "key2": "val2",
    "key3": "val3",
    ...
}

and get something like this:

<select>
    <option value="key1">val1</option>
    <option value="key2">val2</option>
    <option value="key3">val3</option>
    ...
</select>

I read docs, but I can't understand how to achieve this.

Answer 1

use ng-option:

<select ng-model="blah" ng-options="key as value for (key , value) in data"></select>

or use ng-repeat:

<select>
    <option ng-repeat="(key, value) in data" value="{{key}}">{{value}}</option>
</select>

data in controller:

$scope.data = {
    "key1": "val1",
    "key2": "val2",
    "key3": "val3",
    ...
};
