我有一个HTML文件中像Map.Html谷歌地图无法正确加载在Web浏览器控件
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title></title>
<script type="text/javascript" src="http://maps.google.com.mx/maps/api/js?sensor=true"></script>
<script type="text/javascript">
var geocoder;
var map;
function initialize() {
geocoder = new google.maps.Geocoder();
var myOptions = {
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var address = "Ahmedabad, India" //change the address in order to search the google maps
geocoder.geocode({ 'address': address }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
var infoWindow = new google.maps.InfoWindow({
content: 'Hello'
});
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.open(map, marker);
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
然后我用下面的代码加载WebBrowser控件DocumentText这个HTML文件:
using (StreamReader reader = new StreamReader(System.Windows.Forms.Application.StartupPath + "\\Map.html"))
{
_mapHTML = reader.ReadToEnd();
}
webBrowser1.DocumentText = _mapHTML;
但地图加载不正确。 放大/缩小,地图/卫星选项,标记正在显示,但在地图显示上显示一个白色图层。
3.3是退役的版本,所以在内部它采用当前的冻结版本如3.20加载地图。 –
