我可以使用ng-model setter-getter选项转换模型中变量的值吗？

Question

I have the following situation in angularjs :

<select ng-model="value">
    <option ng-repeat="type in types">{{type.description}}</option>
<select>

The controller looks like:

$scope.value = null;
$scope.types=[{description: "asdf", id:"a"}, {description: "basdf", id:"b"}];

I want to set $scope.value, not with the value of type.description , but with the value of its corresponding id: type.id . But I still want to show the description in the dropdown select.

Can I accomplish this using the getterSetter option of ng-model ? I have looked the documentation and it does not clarify much.

You don't need getterSetter to do that. All you need is ng-options :

<select ng-model="value" ng-options="type.id as type.description for type in types">
</select>
