html代码

<div ng-app="DnApp" ng-controller="SeasonDetailController">
<seamonthdetail seamon="seasonMonth" getseadatas="getSeasonDetailData(month)"></seamonthdetail>
</div>

controller代码

var DnApp=angular.module("DnApp",[]);
DnApp.controller('SeasonDetailController',function($scope){
    $scope.seasonMonth=new Date().getMonth()+1;
    $scope.getSeasonDetailData=function(month){
        console.log(month);
    }  
})

directive代码

DnApp.directive('seamonthdetail',function(){
    return {
        restrict:"EA",replace:true,transclude:true,templateUrl:"/src/tpls/season/monthdetail.html",scope:{
            seamon:"=",/*使用本地别名 seasonmonths:"=seamon" */
            getseadatas:"&"
        },link:function(scope,element,attrs){
            scope.isCurrent=function(name,value){
                if(name==value){
                    return true;
                }else{
                    return false;
                }
            }
            scope.getseasondatas=function(month){
                scope.seamon=month;
                /*调用别名,双向绑定失效 scope.seasonmonths=month */
/*一定记着，如果函数存在形参，那调用时，一定用对象的形式传递实参*/
                scope.getseadatas({month:month});
            }

        }

    }
})

seasondetail.html代码

<div class="flexBox"> <span ng-class="{true:'active'}[isCurrent(seamon,x.month)]" ng-click="getseasondatas(2)" > <i>{{2}}月</i> </span> </div> /*为了突出函数调用的注意传参的情况，再举个例子。注意这里的实参传递形式*/ <div class="flexBox"> <span ng-class="{true:'active'}[isCurrent(seamon,x.month)]" ng-click="getseadatas({month:2})" > <i>{{2}}月</i> </span> </div>
