Angular JS1 - Disable submit button until form is valid

Disable submit button when form invalid with AngularJS

To void this, you just need to handle $pending state of the form:

<form name="myForm">
  <input name="myText" type="text" ng-model="mytext" required />
  <button ng-disabled="myForm.$invalid || myForm.$pending">Save</button>
</form>
