创建列表输入选中的数组以发布REST API

Question

I've used .push() to create "List" input checked array for posting REST API. But it doesn't seem right.

When unchecking, the item in array is not removed automatically. Anybody have a better solution, pls help me! Tks

You could do this... it works. Can't say this is the best solution though

 $scope.$watch('lists', function(lists){
    $scope.count = 0;
    angular.forEach(lists, function(list){
      if(list.checked){
        $scope.count += 1;
        if (inputsList.indexOf(list.id) == -1) {
            inputsList.push(list.id);
        };
      } else {
          inputsList.pop(list.id);
      }
    })
  }, true);

Same logic, but, modified a lil

index.html (added ng-click)

<input type="checkbox" name="list_id[]" ng-model="list.checked" value="{{list.id}}" ng-click='updateItem(list)' />

app.js (removed $scope.$watch and...)

$scope.currentSelectedItem = [];      
$scope.updateItem = function(item) {
    if(item.checked) {
        $scope.currentSelectedItem.push(item);
    } else {
        $scope.currentSelectedItem.pop(item);
    }   
}
