我正在尝试运行一个在 ng-click 按钮上的函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。我正在尝试运行一个按钮的 ng-click 函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。我正在尝试运行一个按钮的 ng-click 函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。我正在尝试运行一个按钮的 ng-click 函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。我正在尝试运行一个按钮的 ng-click 函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。我正在尝试运行一个按钮的 ng-click 函数。我已经尝试了很多东西，但似乎仍然没有用。我的功能附加到范围。

var app= angular.module('mainApp', []);

    $scope.markers=[];
    $scope.myLatLng={lat: 43.6532, lng: -79.3832};

                center: $scope.myLatLng,
                zoom: 7,
                mapTypeId: 'roadmap'

        });

    };

    $scope.removeMarkers= function () {
    console.log("working")

Answer 1

您使用 ng-click="removeMarkers()" 的代码块未附加到任何范围。直到稍后，您才将控制器附加到 <table> 元素上。

如果您将 ng-controller=".." 指令移到 DOM 树中更高的位置，您的代码应该会按预期工作。例如在 <body 元素上。

<body ng-app="mainApp" ng-controller="institutions">
