如何从对话框控制器中访问md-dialog onComplete？

Question

$ mdDialog.show接受onComplete函数，该函数在show动作完成后触发。请参阅https://material.angularjs.org/latest/api/service/ $ mdDialog＃show。

如何从对话框控制器（而不是调用对话框的父控制器）中获取相同的onComplete功能？

Answer 1

来自父控制器：

var onCompleteDeferred = $q.defer();
$mdDialog.show({
    templateUrl: '/app/dialog.html',
    controller: 'dialogController',
    onComplete: onCompleteDeferred.resolve,
    locals: {
        loadingPromise: function () {
            return onCompleteDeferred.promise;
        },
        success: function() {}
    }
})

在对话框的控制器中：

myApp.controllers.controller("dialogController", [
    "success",
    "loadingPromise",
    function (
        success,
        loadingPromise
    ){
        loadingPromise().then(function() {
            //everything in here is guaranteed to be ran AFTER the dialog has been opened
        });
    }
)
