map组件，动态修改longitude,latitude之后，map定位不能移动到中心，有时候可以，有时候不能，用的是wepy框架

      <map

          id=“map”

          scale="{{scale}}"

          controls="{{controls}}"

          bindcontroltap=“controltap”

          markers="{{markers}}"

          latitude="{{latitude}}"

          longitude ="{{longitude }}"

          bindmarkertap=“markertap”

          bindregionchange=“regionchange”

          bindtap=“mapclick”

          show-location = “{{showlocation}}”

          style=“width:100%;height:{{Mapheight}}”

          bindupdated =“mapupdated”

          setting="{{setting}}"
