getData 方法 ol.utfGrid.getData(lonlat)

自定义默认的 onMove 方法

new ol.utfGrid({\"url\":\"utfgrid_url_source\"})

ol.utfGrid.onMove = function(evt){console.log(evt.coordinate)}

ol.utfGrid.addTo(ol.Map)

new ol.utfGrid({\"url\":\"utfgrid_url_source\"})

ol.utfGrid.onMove = function(evt){console.log(evt.coord)}
