您可以使用地理位置数据来做非常有趣的事情,例如在Google地图上显示用户位置。以下示例将根据通过HTML5地理位置功能检索的纬度和经度数据显示您在Google地图上的当前位置。
例试试这个代码»
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Using the Google Maps</title>
<script>
function showPosition() {
navigator.geolocation.getCurrentPosition(showMap);
}
function showMap(position) {
// Get location data
var latlong = position.coords.latitude + "," + position.coords.longitude;
// Set Google map source url
var mapLink = "https://maps.googleapis.com/maps/api/staticmap?center="+latlong+"&zoom=16&size=400x300&output=embed";
// Create and insert Google map
document.getElementById("embedMap").innerHTML = "<img alt='Map Holder' src='"+ mapLink +"'>";
}
</script>
</head>
<body>
<button type="button" onclick="showPosition();">Show My Position on Google Map</button>
<div id="embedMap">
<!--Google map will be embedded here-->
</div>
</body>
</html>
