ng-options with object data source

angularjs, ng-options

Solution

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>

Problem

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? See plunkr here: http://plnkr.co/edit/Bl6u4151KyDkxhYrsdCm?p=preview
