angular 中 directive中的多个指令

<div ng-controller="ctrl1">
    <superman weight length speed>superman</superman>
    <superman weight >weight</superman>
</div>

<script type="text/javascript">
    angular.module('myMoudle',[])
            .controller('ctrl1', ['$scope', function($scope){

            }])
            .directive("superman", function(){
                return {
                    restrict : "E",
                    scope : {},
                    controller : function($scope){
                        $scope.abilities = [];

                        this.addWeight = function(){
                            $scope.abilities.push("Weight");
                        }

                        this.addSpeed = function(){
                            $scope.abilities.push("Speed");
                        }

                        this.addLength = function(){
                            $scope.abilities.push("Length");
                        }
                    },
                    link : function(scope, element){
                        element.bind("mouseenter", function(){
                            console.log(scope.abilities);
                        })
                    }
                }
            })
            .directive("weight", function(){

                    restrict : "A",
                    require : "superman",
                    link : function(scope, element, attrs, superman){
                        superman.addWeight();
                    }
                }
            })
            .directive("speed", function(){

解释： directive 中的controller放一些公共部分

       require : 通过require让多个指令共享controller中的数据

                 ^ 允许从父类开始查找 require:"^superman"

                 ? 如果找不到不抛出异常

scope :   {} 创建独立作用域，没有原型继承

             = or =attr “Isolate”作用域的属性与父作用域的属性进行双向绑定，任何一方的修改均影响到对方，这是最常用的方式；

              @ or @attr “Isolate”作用域的属性与父作用域的属性进行单向绑定，即“Isolate”作用域只能读取父作用域的值，并且该值永远的String类型；

              & or &attr “Isolate”作用域把父作用域的属性包装成一个函数，从而以函数的方式读写父作用域的属性，包装方法是$parse;
