我的控制台函数this.dialogRef.close（）

function (dialogResult) {
    var _this = this;
    this._result = dialogResult;
    // Transition the backdrop in parallel to the dialog.
    this._containerInstance._animationStateChanged.pipe(Object(rxjs_operators__WEBPACK_IMPORTED_MODULE_8__["filter"])((/**
     * @param {?} event
     * @return {?}
     */
    function (event) { return event.phaseName === 'start'; })), Object(rxjs_operators__WEBPACK_IMPORTED_MODULE_8__["take"])(1))
        .subscribe((/**
     * @param {?} event
     * @return {?}
     */
    function (event) {
        _this._beforeClosed.next(dialogResult);
        _this._beforeClosed.complete();
        _this._overlayRef.detachBackdrop();
        // The logic that disposes of the overlay depends on the exit animation completing, however
        // it isn't guaranteed if the parent view is destroyed while it's running. Add a fallback
        // timeout which will clean everything up if the animation hasn't fired within the specified
        // amount of time plus 100ms. We don't need to run this outside the NgZone, because for the
        // vast majority of cases the timeout will have been cleared before it has the chance to fire.
        _this._closeFallbackTimeout = setTimeout((/**
         * @return {?}
         */
        function () {
            _this._overlayRef.dispose();
        }), event.totalTime + 100);
    }));
    this._containerInstance._startExitAnimation();
