        function($http){
            this.list = [];
            this.userlist =[];
            var noticelist = this;
            this.get = function(){
               $http.get(‘/m/employee/get_noticelist‘).success(function(data){
                   //console.log(data.data);
                    if(data.status==‘200‘){
                        noticelist.list = data.data;
                        for(var i in  noticelist.list){
                        noticelist.list[i].context=$sce.trustAsHtml(data.data[i].context);
                         }

                    }else{
