如何对脚本传值和取值？

在vb里如何吧值传到脚本的address里，又如何获取showAddress的返回值呢？


    <script type="text/javascript">

    function showAddress(address) {
      if (geocoder) {
        geocoder.getLatLng(
          address,
          function(point) {
            if (!point) {
              alert(address + " not found");
            } else {
              map.setCenter(point, 15);
              var marker = new GMarker(point, {draggable: true});
              map.addOverlay(marker);
              GEvent.addListener(marker, "dragend", function() {
                marker.openInfoWindowHtml(marker.getLatLng().toUrlValue(6));
              });
              GEvent.addListener(marker, "click", function() {
                marker.openInfoWindowHtml(marker.getLatLng().toUrlValue(6));
              });
      GEvent.trigger(marker, "click");
            }
          }
        );
      }
    }
    </script>
