angularjs select required not working ng-options

Question

I am trying to ensure a user selects a value from a select box before submitting the form. This works correctly with static options; it however fails when populating the options via a model using ng-options

I am using AngularJS 1.2.9

Thank you in advance.

Isn't it because you didn't add any <option></option> ? See this plunkr – Segalman

Answer 1

In your example changing the data bound select to the following fixes the required directive. I'm not sure why exactly.

<select ng-model="selectedValue1" ng-options="opt for opt in ['Mazda2','Maxda3']" required>
  <option></option>
</select>

It's the '<option></option>' tags that make it works – Hallucinogen

Answer 2

You can also try ng-required="true" (it works on the latest AngularJS, not sure for 1.2.x).

<select ng-model="selectedValue1" ng-options="opt for opt in ['','Mazda2','Maxda3']" ng-required="true"></select>
