The default value is not ? object:null ? in select option Angularjs

Question

This is code in file js

$scope.ListOption = [];
$scope.ListOption.push({ Value: "0", Name: Car });
$scope.ListOption.push({ Value: "1", Name: House });

Here's what the code HTML looks like

<select class="form-control" id="Category" ng-model="Category">

<option ng-repeat="option in ListOption" value="{{option.Value}}">
 {{option.Name}}</option>

</select>

The generated html is

<select class="form-control ng-pristine ng-valid" ng-model="Category" style="padding: 0px;">
<option value="? object:null ?"></option>
<option ng-repeat="option in ListOption" value="0" class="ng-binding ng-scope">Car</option>
<option ng-repeat="option in ListOption" value="1" class="ng-binding ng-scope">House</option>
</select>

I have quite a headache on this issue. Looking forward to having someone help me the other way.

Should be using ng-options rather than ng-repeat

it's wrong. you are matching with option. Change it. I suggest, use the track by $index for no repeat options

<option value="{{option.Value}}" ng-repeat="option in ListOption track by $index">
 {{option.Name}}
</option>

Doesn't make sense to repeat the <select>

Kenry Sanchez Over a year ago

it doesn't repeat the select. it repeats the <options> tag.

No, that's not how ng-repeat works. It repeats the element that you set it on, not it's children

Still not your friend, it still defaults to the first one <option value="? object:null ?"></option>

Kenry Sanchez Over a year ago

it does with the {{option.Value}}??

I think the mistake is that you used the main array to get value instead of iterable option object. Actually, this should work:

<select class="form-control" id="Category" ng-model="Category">
<option ng-repeat="option in ListOption" value="{{option.Value}}">
 {{option.Name}}
</option>
</select>

No. ListOption is the List. he needs to show the option name

Alexandr Over a year ago

Sorry, I just forgot to change ListOption to the option for the Name too.
