Question

如果你有一个包含ng-repeat的指令，你想修改＆＃34;跟踪＆＃34;或＆＃34; as＆＃34; ng-repeat怎么做而不在模板中创建两个单独的ng-repeats？我希望能够通过ng-repeat作为指令属性传入轨道。所以在字符串数组的情况下，它就像是repeat-track-by =＆＃34; row＆＃34;在对象数组的情况下，它将是repeat-track-by =＆＃34; row.title＆＃34;。有没有办法实现这个目标？

＆＃13;

angular.module("app", []);

angular.module("app")
.controller("appCtrl", function($scope) {
  $scope.sampleData = ["sample 1", "sample 2", "sample 3"];
  $scope.sampleData2 = [{title:"sample 1"}, {title:"sample 2"}, {title:"sample 3"}];
})

angular.module("app")
.directive("repeatDirective", function() {
  return {
        restrict: 'E',
        scope: {
            data: '='
        },
        template: "<div ng-repeat='row in data track by row'>{{row}}</div>",
        link: function (scope) {}
    }
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<body ng-app="app">
  <div ng-controller="appCtrl">
    <repeat-directive data="sampleData"></repeat-directive>
  </div>
</body>

通过＆＃34;修改ng-repeat＆＃34;轨道;或＆＃34; as＆＃34;在角度指令中
