[英]AngularJS change select option ng-click
It is simple i know but just bugging me i got the following code 我知道这很简单,但是只是烦我,我得到了以下代码
<label>Role</label><div>
<select ng-change="save()" ng-model="frm.TypeID">
<option ng-value="">Select Role</option>
<option ng-value="1" value="1">Admin</option>
<option ng-value="3" value="3">User</option>
<option ng-value="2" value="2">Guest</option>
</select>
I get the ng-value from the database but can not update it via the controller so how can i do something like 我从数据库获取ng值,但无法通过控制器更新它,所以我该怎么做
angular.controller('testCtrl',['$scope', function($scope){
$scope.select=function(){
$scope.frm.TypeID = 3;
}
}]);
Thanks 谢谢

{id: 2, label: 'User'},
{id: 3, label: 'Guest'}

$scope.frm = {
TypeID: 3
};
// fetch value from database then update value
fetchData().then(function (id) {
$scope.frm.TypeID = id;
}
