        })
      },
      tianjia(event){
        stream.fetch({
                    method:"POST",
                    type:'json',
                    url:'http://XXX.com/XXX/XXX',
                    headers:{'Content-Type':'application/x-www-form-urlencoded'},
                    body:this.toParams(
                            {
                                hospital_id:2,
                                department_id:16,
                                shijuan_id:this.normalpickData,
                                patient_id:this.normalpickData1,
                            })
                }, function(data) {
                    if(data.data.code!=0){
                        modal.toast({
                            'message': data.data.msg,
                            'duration': 2.0
                        })
                    }else{
                        modal.toast({
                            //message: JSON.stringify(data),
                            message: data.data.msg,
                            duration: 2.0
                        })
                    }
                },function(progress) {
                })
      },
      toParams(obj) {
        var param = ""
        for(const name in obj) {
            if(typeof obj[name] != 'function') {
                param += "&" + name + "=" + encodeURI(obj[name])
            }
        }
        return param.substring(1)
    },
    }
  }
</script>

这个选中的为何是下标，不是当前的值，我这个算是单页应用吧，如何进入当前页面触发一个函数，将查到的数据压入到items数组。
