2、directive-directive.js：
var myModule = angular.module("app",[]);
myModule.directive('superman',function(){
return {
restrict:'AE',
scope:{},
controller:function($scope){
$scope.abilities = []; //定义能力集合
this.addstrength = function(){//指令中的controller是一个公开暴露的api接口，一般是供后面定义该标签内的属性指令调用执行的
$scope.abilities.push("strength");
};
this.addspeed = function(){
$scope.abilities.push("speed");
};
this.addlight = function(){
$scope.abilities.push("light");
};
},
link:function(scope,element,attrs){//link里面可以操纵DOM元素本身以及元素属性还有全局scope作用域内的方法
element.addClass('btn btn-primary');
element.bind("mouseenter", function() {
console.log(scope.abilities);
});
}
}
}).directive('strength',function(){//一个属性代表一个值
return {//restrict:这里不写默认的是属性指令
require:'^superman',//依赖superman指令，并在link方法中注入第四个参数supermanCtrl，即superman的控制器参数,并通过该参数调用控制器里面的暴露方法
link:function(scope,element,attrs,supermanCtrl){
supermanCtrl.addstrength();
}
}
}).directive('speed',function(){
return {
require:'^superman',
link:function(scope,element,attrs,supermanCtrl){
supermanCtrl.addspeed();
}
}
}).directive('light',function(){
return {
require:'^superman',
link:function(scope,element,attrs,supermanCtrl){
supermanCtrl.addlight();
}
}
});
