ng-options with object data source
AngularjsNg OptionsAngularjs Problem Overview
I'm struggling to understand how ng-options works with a data source. I've read the docs and I feel like I'm doing exactly what is required, but I still get problems when attempting.
<!DOCTYPE html>
<html ng-app="app">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"> </script>
<link rel="stylesheet" href="style.css" />
<script type="text/javascript">
angular.module('app', [])
.controller('IndexCtrl', ['$scope', function($scope) {
$scope.types = {
1: "value1",
2: "value2",
5: "value3"
};
}]);
</script>
</head>
<body ng-controller="IndexCtrl">
<select ng-model="type" ng-options="k as v for(k, v) in types">
<option value="">Select Type</option>
</select>
</body>
</html>
I always get this error in the console:
Error:
> Expected ngOptions in form of 'select (as label)? for (key,)?value in collection (track by expr)?' but got 'k as v for(k, v) in types'.
What am I doing incorrectly?

This is kind of strange, but it seems like you need to put a space after for. This works:
<select ng-model="type" ng-options="k as v for (k, v) in types">
<option value="">Select Type</option>
</select>
