How to get checkbox value in angularjs?

问题:

I have a 10(or n)checkbox in my ng-view. Now I would like to ask here that What is the most efficient or simple way to check if checkbox is checked and if checked get the value of checkbox.

<ul>
  <li ng-repeat="album in albums">
   <input type="checkbox" ng-model="folder.Selected" value={{album.name}} />
   </li>
  </ul>

I have ng-controller(getAlbumsCtrl), in that I have an array in which I want to push all the checkedbox albums names into albumNameArray

回答1:

You can loop over the array to find out which is selected and push into the name array.

<ul>
  <li ng-repeat="album in albums">
    <input type="checkbox" ng-model="album.selected" value={{album.name}} />
  </li>
</ul>

$scope.save = function(){
  $scope.albumNameArray = [];
  angular.forEach($scope.albums, function(album){
    if (!!album.selected) $scope.albumNameArray.push(album.name);
  })
}

// alternatively you can use Array.prototype.filter on newer browsers (IE 9+)
$scope.save = function(){
  $scope.albumNameArray = $scope.albums.filter(function(album){
    return album.selected;
  });
}

Have a look at this fiddle,i have used the object whose key is the album name

<input type="checkbox" ng-model="folder[album.name]" value={{album.name}}/>

controller:

function ctrl($scope){
$scope.albums = [{name:'a1'},{name:'a2'},{name:'a3'}];
$scope.folder = {};
$scope.albumNameArray = [];
$scope.getAllSelected = function(){          
    angular.forEach($scope.folder,function(key,value){
        if(key)
            $scope.albumNameArray.push(value)
    });
}}

You could simply use angular filter here, also your ng-model should be album.Selected instead of folder.Selected

Html

{{(albums | filter : { Selected: true }: true)}}

Controller

$scope.albumNameArray = $filter('filter')($scope.albums, { Selected: true }, true);

Before using it in controller don't forget to add $filter in your controller

If you want to get the value printed.
You can use like :

input type="checkbox" ng-model="checkboxModel.value2" ng-true-value="'YES'" ng-false-value="'NO'"
