但是，您不会在plunker上看到错误。在本地或从web服务器运行代码时会出现错误


提前感谢您对这个问题的帮助。
似乎是
typeahead
中的一个缺陷

解决方法是：-初始化$scope.matches，这是
typeahead
本身应该完成的


  $scope.data = {};
  $scope.data.selected = "";
  $scope.matches = [];//workaround


工作：


  $scope.data = {};
  $scope.data.selected = "";
  $scope.matches = [];//workaround
