Question

我很抱歉打扰了，我在Angular遇到了问题。

这个框架很新，我试图用一个选项来设置一个处方集。但出于某种原因，在html页面中，我有一个国家列表，但它是空的。

有人可以提示如何通过它吗？

提前致谢

    { name: 'B' },

  $scope.selectedCountry = { name: 'A' };
});

Answer 1

更正默认选定的参考。

所以将$scope.selectedCountry = { name: 'A' };更改为$scope.selectedCountry = $scope.locations[0];

工作演示：

var myapp = angular.module('myapp', []);
myapp.controller('FirstCtrl', function($scope) {
  $scope.locations = [{
      name: 'A'
    },
    {
      name: 'B'
    },
    {
      name: 'C'
    }
  ];
  $scope.selectedCountry = $scope.locations[0];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp">
  <fieldset ng-controller="FirstCtrl">
    <select ng-options="location as location.name for location in locations" ng-model="selectedCountry"></select> {{ selectedCountry }}
  </fieldset>
</div>

Answer 2

我刚刚发现我可以创建多个模块，但不能在同一页面中放置多个ng-app。它现在工作得很好。

使用AngularJS中的选项设置选择
