将JSON获取请求项推入数组

Question

I'm trying to push json objects into an array with angular. I'm getting an error 'Cannot read property 'push' of undefined'. Is there another way to do this with angular?

$.each(data.Document.Placemark, function(index, item) {
   var locations = [];
  $scope.locations.push(item.name + ", " + item.Point.coordinates);
});

Answer 1

如果希望locations是$scope的属性，则必须使其成为$scope的属性，而不是局部变量。

$scope.locations = [];

Answer 2

.push method is only used for arrays. You should define an array first before using .push You should do this:

$.each(data.Document.Placemark, function(index, item) {
   $scope.locations = [];
   $scope.locations.push(item.name + ", " + item.Point.coordinates);
});
