define(['js/home/directives/directives'],function(directives){
'use strict';
console.log(directives);
directives.directive('navHeader', ['username',function (username) {
//directive中service的数据username传给模板，该怎么做？
return {
restrict: 'ECAM',
templateUrl: 'js/home/template/nav-header.html',
replace: true
}
}]);});
Directive中Scope 用等号，实现双向绑定
从注入的username的返回值中获取到你想要的值然后绑定到$scope上
