Trouble With AngularJS And Select Binding Not Loading Default Values

I am having trouble with a input and binding with AngluarJS. I've created a minimum working sample on Plunker: http://plnkr.co/edit/P4T25RoJrU4mvbBiUJ9S?p=preview. T Solution 1: Two issues: Compare strings to strings Be careful when using select as and track by in the same expression. JS angular.module('defaultValueSelect', []) .controller('ExampleController', ['$scope', function($scope) { $scope.data = { availableOptions: [ {id: '1', name: 'Option A'}, {id: '2', name: 'Option B'}, {id: '3', name: 'Option C'} ], //USE this selectedOption: '2' //NOT this //selectedOption: 2 //This sets the default value }; }]); Copy HTML <!-- remove 'track by option.id' --> <select name="mySelect" id="mySelect" ng-options="option.id as option.name for option in data.availableOptions track by option.id" ng-model="data.selectedOption"> </select> Copy From the Docs: Be careful when using select as and track by in the same expression. This will work: <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"> </select> Copy but this will not work: <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"> </select> Copy -- AngularJS ng-options Directive API Reference Solution 2: As requested by OP, adding the comment as the answer. If you remove the "track by option.id" from the ng-options as following, it should pre-select based on your model. <select name="mySelect" id="mySelect" ng-options="option.id as option.name for option in data.availableOptions" ng-model="data.selectedOption"></select> Copy Check out the modified Plunker: http://plnkr.co/edit/b4ddyA5Q4jGNcJI1d8eW?p=preview Share Post a Comment for "Trouble With AngularJS And Select Binding Not Loading Default Values" Top Question Activating Onbeforeunload Only When Field Values Have Changed What I'm trying to achieve is to Warn the user of unsav… Onpropertychange For A Textbox In Firefox?
