我正在尝试为高图创建angular指令。

下面是我的代码

var myMapDirectives = angular.module('MapDirectives', ['myMapControllers']);

    // Directive
    myMapDirectives.directive('myMap', function($http) {
        console.log("In my-Map directive");

        return {
            restrict: 'EAC',
            template: '<div></div>',
            replace: true,
            controller: 'myMapController',
            scope: {
                widget: '='
            },
            link: function(scope, iElement, iAttrs) {
                console.log("In my-map link function.", scope, iElement, iAttrs);                                      

                var chart;
                var process = function(){
                   var defaultOptions = {
                        chart: {
                            renderTo: iElement[0]
                        },
                    };
                    var widget = angular.extend(defaultOptions, scope.widget);
                    chart = new Highcharts.Map(widget);
                };
                process();
                scope.$watch("widget.series", function(loading){
                    process();
                });
                scope.$watch("widget.loading", function(loading){
                    if(!chart){
                        return;
                    }
                    if(loading){
                        chart.showLoading();
                    } else {
                        chart.hideLoading();
                    }                    
                });                                    
            }
        };
    });

控制器有点大，因为我把所有的JSON数据都放在了mapData属性中。

在这里我的代码是可用的Highmaps Directive & Controller。

问题图未显示。

(我使用此链接创建指令Plunker )

javascript

angularjs

controller

directive
