我不喜歡預設的marker mouseover的style,可以改嗎?

var map;
function init() {
	map = new UMap(document.getElementById(’map’));
	map.centerAndZoom(new ULatLng(25.035405, 121.520255), 9);
	var mapDiv = document.getElementById(’map’);
	var marker = new UMarker(map.getCenter());
	bindMaukerMouseover(marker, ‘this is a string!’);
	map.addOverlay(marker);
	var marker2 = new UMarker(new ULatLng(25.033405, 121.523255));
	bindMaukerMouseover(marker2, ‘this is another string!’);
	map.addOverlay(marker2);
	//My marker info Div
	var myMarkerInfoDiv = document.createElement(’div’);
	myMarkerInfoDiv.id = ‘myMarkerInfoDiv’;
	myMarkerInfoDiv.style.cssText = ‘width:200px;border:1px solid blue;display:none;position:absolute;background-color:#CCC;’;
	document.getElementById(’map’).appendChild(myMarkerInfoDiv);
}

function bindMaukerMouseover(mkr, msg){
	mkr.addListener(’mouseover’, function(){
		var latlng = mkr.getPoint();//取得該座標的經緯度
		var point = map.transformLatLngToContainerCoordinates(latlng);//將經緯度轉成螢幕座標（相對於mapDiv左上角）
		var exX = 15;//x偏差量
		var exY = 10;//y偏差量
		document.getElementById(’myMarkerInfoDiv’).style.left = (point.x + exX) + ‘px’;
		document.getElementById(’myMarkerInfoDiv’).style.top = (point.y + exY) + ‘px’;
		document.getElementById(’myMarkerInfoDiv’).style.display = ‘block’;
		document.getElementById(’myMarkerInfoDiv’).innerHTML = msg;
	});
	mkr.addListener(’mouseout’, function(){
		document.getElementById(’myMarkerInfoDiv’).style.display = ‘none’;
	});
}
