1、父controller，负责监听并广播
//监听：若收到change，把值广播出去
$scope.$on(“change",function (event, msg) {
$scope.$broadcast(“changeFromBody", msg);
});
2、子controller，负责把变量发给父controller
//向父controller传值$scope.value
$scope.$emit(“change", $scope.value);
3、子controller，负责监听父controller的广播，给变量赋新值
//监听父controller的广播，得到changeFromBody广播时取$scope.value
$scope.$on(“changeFromBody",function (event, msg) {
$scope.value = msg;
});
