      var list = [{}]

      if(queryString && queryString.length>0){

        let parms = {

          name:queryString

        }

        providerformFindProvider(parms).then(res=>{

          if(res.status == "ok"){

　　　//处理成自己想要的格式

            list = res.data.map(item=>{

              return {

                id:`${item.id}`,

                value:`${item.name}`

              }

            })

            callback(list);

          }

        })

      }

    },

    handleProvidername(item){

      this.query.providername = item.value;

      this.providername = item.value;

    },
