Ng-options Doesn't Show The Ng-model Object In The Select Box On Load (angularjs)
I have a html select input. Here I use AngularJS:
Solution 2:
You need init your variable t.selected like this $scope.t.selected = $scope.t.Valgalternativer[0];.
Live example on jsfiddle.
angular.module('app', ['ngAnimate'])
.controller('controller', function($scope) {
$scope.t = {

Oh... I understand. You define t.selected in your variable t. But it doesn't work, because
{
"Siffer": "99",
"Tekst": "Annen utvendig kledning – må spesifiseres",
"Tekst2": null,
"Kode": null,
"Delalternativer": null
}!= {
"Siffer": "99",
"Tekst": "Annen utvendig kledning – må spesifiseres",
"Tekst2": null,
"Kode": null,
"Delalternativer": null
}
Another word are not equal.
$scope.t.Valgalternativer[$scope.t.Valgalternativer.length-1]!=$scope.t.selected
Try this
$scope.t.selected = .Valgalternativer[$scope.t.Valgalternativer.length-1];
Solution 3:
edit
As per your comment, for this to work, one way is to set the selected property like this.
$scope.t.selected =$scope.t.Valgalternativer[2];
If the object comes from another service or json, you may have to find/filter from t.Valgalternativer and then assign appropriate index.
This is so because, as pointed out in other answer, if you initialize selected the way you are doing, it will be a new object whose hash value is different.
If you like this approach, please remove the "selected" property from t and add it separately as above. There is no need to change any markup.
initial
Try this
<selectclass="form-control"
ng-model="t.selected"
ng-options="option | matriseValgFilter as option | matriseValgFilter for option in t.Valgalternativer"
ng-change="change(t.selected)"
ng-init='t.selected = "99 - Annen utvendig kledning – må spesifiseres"'>
</select>
The viewValue of the option you choose should match with value of one of the options of select.
as syntax is used to set value for options in select. Documentation here.
Solution 4:
None of the answers worked properly in my actual application, but solved it using a method in the controller that I call with ng-init.
Ended up with this:
<selectclass="form-control"
ng-init="loadMatriseValg(node, t)"
ng-model="t.selected"
ng-options="option | matriseValgFilter for option in t.Valgalternativer"
ng-change="changeMatrise(node, t.selected, '{{t.selected.Kode}}')"></select>
Then in the controller I have this:
$scope.loadMatriseValg = function (node, t) {
// user has not selected anything, set default valueif (!t.selected) {
t.selected = t.Valgalternativer[0];
}
// loop through all valg alternativerfor (var v = 0; v < t.Valgalternativer.length; v++) {
if (t.Valgalternativer[v].Siffer == t.selected.Siffer) {
t.selected = t.Valgalternativer[v];
return;
}
}
}
