javascript - AngularJS - 将 $scope.data 重置为原始值

Question

我在这里创建了一个 fiddle :http://jsfiddle.net/nicktest2222/W4VaA/

我只是希望能够按下重置按钮并恢复原始值。有谁知道执行此操作的最佳方法吗？

提前致谢

function TodoCtrl($scope) {
  $scope.data = [
   {text:'learn angular', done:true},
   {text:'build an angular app', done:false}];

  $scope.orig = [$scope.data];

  $scope.reset = function() {
    $scope.data = $scope.orig;
  };

}

The problem is in JS clone mechanics 。您需要做的就是创建模型的深拷贝:

function TodoCtrl($scope) {
    $scope.data = [
        {text:'learn angular', done:true},
        {text:'build an angular app', done:false}
    ];

    $scope.orig = angular.copy($scope.data);

    $scope.reset = function() {
        $scope.data = angular.copy($scope.orig);
    };
}

Here is the updated fiddle.
