My select tag looks like this:
<select ng-model="vm.fooModel"
ng-options="item.id as item.name for item in vm.fooOptions" >
<option value="none">Select</option>
</select>
The problem arises when angular 1.6 renders it, as it removes my default option and adds an empty one
<option value="?" selected="selected"></option>
Initially, "vm.fooModel" is set to "none". This used to work fine in Angular 1.5.
To populate options in a <select> element, you can utilize the ng-repeat method:
angular.module("app",[])
.controller("ctrl", function(){
var vm = this;
vm.fooModel="none";
vm.fooOptions=[
{id: 1, name:"one"},
{id: 2, name:"two"},
];
})<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app" ng-controller="ctrl as vm">
<select ng-model="vm.fooModel">
<option value="none" disabled>Select</option>
<option ng-repeat="item in vm.fooOptions" ng-value="item.id">
{{item.name}}
</option>
</select>
value={{vm.fooModel}}
</body>For further details, visit AngularJS <select> Directive API Reference - Using ngRepeat to generate select options.
Include a default option in an array of choices within the controller.
angular.module("app", [])
.controller("ctrl", function() {
var vm = this;
vm.fooModel = "none";
vm.fooOptions = [{
id: "none",
name: "default"
},
{
id: 1,
name: "one"
},
{
id: 2,
name: "two"
},
];
})<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app" ng-controller="ctrl as vm">
<select ng-model="vm.fooModel" ng-options="item.id as item.name for item in vm.fooOptions">
</select>
Selection: {{vm.fooModel}}
</body><option ng-repeat="element in vm.choices track by element.key" ng-value="element.value">
