AngularJS Material mdDialog 并在模板中显示局部变量

Question

生成 mdDialog 的部分控制器看起来像

$scope.removeAttendee = function(item) {

    console.log(item);

    $mdDialog.show({
        controller: DialogController,
        templateUrl: 'views/removeMsg.tmpl.html',
        parent: angular.element(document.body),
        clickOutsideToClose:true,
        controllerAs: 'ctrl',
        fullscreen: $scope.customFullscreen, // Only for -xs, -sm breakpoints.
        locals: {item: item}
    })

和 mdDialog 的控制器：

function DialogController($scope, $mdDialog) {

    var attendee = this;

    $scope.hide = function() {
        $mdDialog.hide();
    };

    $scope.cancel = function() {
        $mdDialog.cancel();
    };

    $scope.save = function(response) {
        $mdDialog.hide(response);
    };

    $scope.remove = function(response) {
        $mdDialog.hide(response);
    };

}

removeMsg.tmpl.html 有代码

<p>You are going to remove {{ ctrl.item.firstName }} {{ ctrl.item.lastName }} from the lunch list.</p>

但我无法显示相关值，即使我将代码更改为

之类的简单代码

locals { item: "test" }

和

的相关部分

{{ ctrl.item }}

关于为什么我没有显示这些值的任何建议？

Answer 1

由于您使用 DialogController 和 controllerAs 别名，您应该将已解析的值分配给控制器上下文 item 变量

function DialogController($scope,$mdDialog,item){//Item value will resolve via locals
    var attendee = this;
    attendee.item = item; // this line is important.

    $scope.hide = function() {
        $mdDialog.hide();
    };

    $scope.cancel = function() {
        $mdDialog.cancel();
    };

    $scope.save = function(response) {
        $mdDialog.hide(response);
    };

    $scope.remove = function(response) {
        $mdDialog.hide(response);
    };
}

除此之外，请将 $scope 方法转换为使用 attendee(this)。由于 controllerAs 模式不鼓励在控制器中使用 $scope。
