在ng-click上设置和显示当前数据？

Question

我正在使用Yeoman - 角度发生器 JSBin：JSBin Link

我有一个简单的机场列表，从工厂angApp.factory("Airports", function() {});设置并从ng-repeat <ul ng-repeat="airport in airports.detail">显示。

我希望进行互动，点击每个链接后，它会与机场代码相匹配，并在新的段落标记<p class="current">Current: {{currentAirport.name}}</p>中显示。

为什么在html中点击机场链接时，setAirport(airport.code)函数不会设置currentAirport.name（或显示？）？

控制器

angular.module("ang6App")
  .controller("AirportsCtrl", function ($scope, Airports) {
    $scope.formURL = "views/_form.html";
    $scope.currentAirport = null;
    $scope.airports = Airports;
    $scope.setAirport = function(code) {
      $scope.currentAirport = $scope.airports[code];
    };

  });

同一模块中的工厂服务

angApp.factory("Airports", function() {
    var Airports = {};
    Airports.detail = {
        "PDX": {
          "code": "PDX",
          "name": "Portland International Airport",
          "city": "Portland",
          "destinations": [
            "LAX",
            "SFO"
          ]
        },
        "STL": {
          "code": "STL",
          "name": "Lambert-St. Louis International Airport",
          "city": "St. Louis",
          "destinations": [
            "LAX",
            "MKE"
          ]
        },
        "MCI": {
          "code": "MCI",
          "name": "Kansas City International Airport",
          "city": "Kansas City",
          "destinations": [
            "LAX",
            "DFW"
          ]
        }
      };
    return Airports;
});

HTML

<div class="container" ng-controller="AirportsCtrl">
  <ul ng-repeat="airport in airports.detail">
    <li><a href="" ng-click="setAirport(airport.code)">{{airport.code}}</a> -- {{airport.city}} </li>
  </ul>
  <p class="current"> current: {{currentAirport.name}}</p>
</div>

Answer 1

您的setAirport函数应写为：

$scope.setAirport = function (code) {
  $scope.currentAirport = $scope.airports.detail[code];
};

但是，这可以通过直接传递实际的airport对象来简化：

<a href ng-click="setAirport(airport)">{{airport.code}}</a>

$scope.setAirport = function (airport) {
  $scope.currentAirport = airport;
};
