var app = new Vue({            el: "#app",            data: function() {                return {                    token: '',                    us_id: '',                    lastClickTime: 0,                    lastClickId: 0                }            },            methods: {                follow:function(nc_id,r_index){                    var this_obj= this;                    var currentTime=new Date().getTime()                    if(this.lastClickId != nc_id){                        this.lastClickId = nc_id;                    }else{                        if(( currentTime - this.lastClickTime)< 300){                            var a_data = {                                token: this_obj.token,                                nc_id: nc_id,                                us_id: this_obj.us_id                            };                            var a_url = "/Info/add_follow_class";                            common_ajax(a_url, a_data, function(res) {                                this_obj.sort.push(res.info)                                this_obj.more_sort.splice(r_index,1)                            }, function(res) {                                api.toast({                                    msg: res.info                                });                            });                        }                    }                    this.lastClickTime = currentTime                }            }        });        app.ready();
