How to enable or disable a button according to a select value? I want a button to be disabled but once a select value is changed to a certain vaue "xxxx" the button is enabled.

Answer 1

Use the ng-disabled directive like this:

<div class="form-group">
    <label class="control-label"> Etat</label>
    <select class="form-control" name="singleSelect"  ng-model="demande.etat">
        <option value="etude">etude</option>
        <option value="Accepte">Accepte</option>
        <option value="Refus">Refus</option>
    </select><br>
</div>

and in the button markup use something like this:

<button ng-disabled="demande.etat != 'Accepte'">
    ....
</button>

angular.module("myApp",[]).
controller("myController",function($scope){
$scope.buttonShow=false;
  $scope.checkVal=function(){
    if($scope.demande.etat == "Accepte"){
      $scope.buttonShow=true;
