Javascript 错误：undefined不是对象（正在计算'；$scope.inputcode.password'；）

HTML:

用户名

{{inputcode.password}您已经声明了
$scope.inputcode
，但不是作为一个对象-因为它当前存在，它只是
未定义的
。您需要将其初始化为对象，如下所示：

$scope.inputcode;
$scope.discountcodes=['phillyd','kevin','john'];

$scope.mylogin = function() {

    for (var i=0; i<$scope.discountcodes.length; i++) {
      if($scope.inputcode.password==$scope.discountcodes[i]){
        console.log($scope.discountcodes[i]);
      }
      else{
        console.log("You failed to crack the code young jedi");
      }
    }
  }

这将允许您将其作为对象进行评估

$scope.inputcode;
$scope.discountcodes=['phillyd','kevin','john'];

$scope.mylogin = function() {

    for (var i=0; i<$scope.discountcodes.length; i++) {
      if($scope.inputcode.password==$scope.discountcodes[i]){
        console.log($scope.discountcodes[i]);
      }
      else{
        console.log("You failed to crack the code young jedi");
      }
    }
  }

$scope.inputcode = {};
