angularjs - 有选择地向 ng-repeat AngularJS 添加一个类

Question

我有一个表的 ng-repeat，我希望能够在 <td> 时添加一个类单击，并在未单击时删除该类。多个 <td>可以同时选择。现在所有的城市都在或没有得到这门课的申请。

例如:(假设节点有 100 个项目)

<tr ng-repeat node in nodes>
  <td>{{node.name}}</td>
  <td>{{node.date}}</td>
  <td ng-click="toggleMe( node.city )" ng-class"{clicked : isClicked()}" >{{node.city}}</td>
</tr>

在我的 JS 中

$scope.cityArr = [];

$scope.toggleMe = function(city) {
  if ($scope.count > 0) {
    angular.forEach($scope.cityArr, function(value) {
      if (city === value) {
        $scope.clicked = false;
      } else {
        $scope.cityArr.push(city);
        $scope.clicked = true;
      }
    });
  } else {
    $scope.cityArr.push(city);
    $scope.clicked = true;
  }
  $scope.count = 1;
};

$scope.isClicked = function() {
  return $scope.clicked;
};

现在只有一个 clicked您正在更改的范围上的属性，所有内容都指向该属性。试着放 clicked而是在节点上...

$scope.toggleMe = function(node) {
  if ($scope.count > 0) {
    angular.forEach($scope.cityArr, function(value) {
      if (node.city === value) {
        node.clicked = false;
      } else {
        $scope.cityArr.push(node.city);
        node.clicked = true;
      }
    });
  } else {
    $scope.cityArr.push(node.city);
    node.clicked = true;
  }
  $scope.count = 1;
};

而在 ngRepeat ...

<tr ng-repeat node in nodes>
  <td>{{node.name}}</td>
  <td>{{node.date}}</td>
  <td ng-click="toggleMe( node )" ng-class"{clicked : node.clicked}" >{{node.city}}</td>
</tr>
