在ng-select中显示地图值

Question

I want to put map values(1,2,3) into select.

<select ng-model="group" ng-options="g.key for g in groups"></select>

$scope.groups is map {'a':'1', 'b':'2', 'c':'3'} I know that by this code :

<select ng-model="group" ng-options="key for (key, g) in groups"></select>

I can put keys. I've tried ng-options="value for(value,g) in groups" but it failed.

Answer 1

Inside this syntax:

ng-options="key for (key, value) in groups"

The (key, value) bit describes the key/value pair. So, value in your case is the value.

So, to use the value you would simply do this:

ng-options="value for (key, value) in groups"
