setting Angular select ng-init to first value in array

All we need is an easy explanation of the problem, so here it is.

I have a simple select element that I am trying to enforce a value being present to submit the form and I have tried both setting the required attribute as well as using ng-init to ensure there is a value selected and both fail.

I am using ng-options to create a list of values from an array of Objects that have a ref property. Then I would like to use ng-init to set the shown value to the first Object.ref in the array.

<select name="refmarker" class="input-block-level form-width-adjust" ng-model="model.refmarker" ng-options="rm.ref for rm in refmarkers" ng-disabled="editable" ng-init="model.refmarker='refmarkers[0].ref'" required></select>

I have tried the following without any luck


Also the required attribute doesn’t work ? Is the angular select element buggy or am I doing something wrong?

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

required will only work in side a form element.

What you want is ng-init=”model.refmarker=refmarkers[0]”

<!doctype html>
<html lang="en" data-ng-app="app">
    <meta charset="utf-8">
    <script src="//"></script>
    <script type="text/javascript">

                    $scope.model = {};
                    $scope.refmarkers = [{ref:'abc'},{ref:'def'},{ref:'ghi'}];
<body ng-controller="Main">
<select ng-model="model.refmarker" ng-options="rm.ref for rm in refmarkers" ng-init="model.refmarker=refmarkers[0]"></select>

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
