javascript - 将函数表达式存储在 angularjs 指令的链接函数中并通过 ng-click 使用它

Question

我有以下 angularjs 指令，我希望能够使用 ng-click 在 property-slider.html 中执行 showMap()。我错过了什么？

(function() {
    'use strict';

    angular
        .module('myapp')
        .directive('propertySlider', propertySlider);

    function propertySlider($timeout) {

        return {
            restrict: 'E',
            templateUrl: 'property-slider.html',
            replace: true,
            scope: {
                property: '=',
                photos: '='
            },
            link: function(scope, element) {
                $timeout(function(){

                    var slider = element.flickity({
                        cellAlign: 'left',
                        cellSelector: '.gallery-cell',
                        lazyLoad: true,
                        wrapAround: true,
                        initialIndex: 1
                    });

                    var showMap = function(){
                        slider.flickity('select', 0);
                    };

                },500);

            }
        };

    }

})();

两个问题....需要将函数分配给作用域，而您不需要在 $timeout 中创建它

link: function(scope, element) {

     scope.showMap = function () {
         element.flickity('select', 0);
     };

     $timeout(function () {

          element.flickity({
             cellAlign: 'left',
             cellSelector: '.gallery-cell',
             lazyLoad: true,
             wrapAround: true,
             initialIndex: 1
         });

     }, 500);
}
