HTML如下：<div class="genderBox">      <div class="fl">             買家             <input type="radio" ng-model="regForm.type" value="buyer"/>      </div>      <div class="fr">             賣家             <input type="radio" ng-model="regForm.type" value="seller"/>      </div>      <div class="cl"></div> </div>Javascript中創建了directive：(function(){ angular.module('homeRegister',[    'ui.router']).directive('homeRegister',function(){    return {         templateUrl:'/frontend/components/modal-home/home-register/home-register.html',         controller:homeRegister     } });function homeRegister($scope,$http,$timeout,Flash,FormFilter){     $scope.regForm={         type:'buyer',     };     $scope.goLogin=function(){         $timeout(function() {             $scope.$parent.isLogin = true;//父scope中         },0);     }; }打開頁面后點擊radio沒有效果。加了name屬性，試了ng-value也都不行。求各路大神幫忙解決一下。。。多謝！
