我想知道是否有办法在我的指令中观察所有$$ isolateBindings？
$scope.$watch('$$isolateBindings', function() {
console.log('watch me plse');
});
现在我这样做：
var isolateBindings = []
angular.forEach($scope.$$isolateBindings, function(item) {
isolateBindings.push(item.attrName)
});
var watchIsValid = $scope.$watchGroup(isolateBindings, function() {
console.log('do somthing');
});

我想它必须是
namespace DataLayer.Repository
{
public class CourseRepository
{
//Add Course
public static void AddCourse(Course a)
{
//Create the SQL Query for inserting a Course
string createQuery = String.Format("Insert Into Course(CourseName,Description,StartDate,EndDate,CourseMode) Values('{0}','{1}','{2}','{3}','{4}');" + "select @@Identity", a.CourseName, a.Description, a.StartDate.ToString("yyyy-mm-dd"), a.EndDate.ToString("yyyy-mm-dd"), a.CourseMode);
//Create and open a connection to SQL Server
SqlConnection connection = DBManager.GetSqlConnection();

这些是受监视的范围属性，而不是属性。
不太可能有另一种直接的方法来做到这一点。原因可能是有争议的，但这种方法足够好，不能再进一步了解。
