请看下面的内容，我认为这是个问题 如果上面的代码在你的控制器中，这个。 selectedCategoryL1不再是词汇$ scope'this'。您需要将此设置为方法之外的var或使用$ scope。 selectedCategoryL1。

var vm = this;
//or use $scope.selectedCategoryL1


.then(response => {
  this.jobCategories = response.data;
  console.log(response.data);
  this.jobCategories.categories.sort(function(a, b) {

    a.child_categories.sort();

    return a.category_name > b.category_name;

  });
  //or replace vm with $scope.
  vm.selectedCategoryL1 = this.jobCategories.categories[0];
  vm.selectedCategoryL2 = this.selectedCategoryL1.child_categories[0];
});
