Answer 1

注：如果您已经有经度/纬度，请参阅Alteveer’s answer。

您需要使用地理定位服务才能获取纬度/经度。谷歌地图已建成之一： http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding

这里有一个如何使用它的一个例子：

<!-- Placeholder for the Google Map --> 
<div id="map" style="height: 512px;"> 
    <noscript> 
    <!-- http://code.google.com/apis/maps/documentation/staticmaps/ --> 
    <img src="http://maps.google.com/maps/api/staticmap?center=1%20infinite%20loop%20cupertino%20ca%2095014&amp;zoom=16&amp;size=512x512&amp;maptype=roadmap&amp;sensor=false" /> 
    </noscript> 
</div> 

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> 
<script type="text/javascript"> 

// Define the address we want to map. 
var address = "1 infinite loop cupertino ca 95014"; 

// Create a new Geocoder 
var geocoder = new google.maps.Geocoder(); 

// Locate the address using the Geocoder. 
geocoder.geocode({ "address": address }, function(results, status) { 

    // If the Geocoding was successful 
    if (status == google.maps.GeocoderStatus.OK) { 

    // Create a Google Map at the latitude/longitude returned by the Geocoder. 
    var myOptions = { 
     zoom: 16, 
     center: results[0].geometry.location, 
     mapTypeId: google.maps.MapTypeId.ROADMAP 
    }; 
    var map = new google.maps.Map(document.getElementById("map"), myOptions); 

    // Add a marker at the address. 
    var marker = new google.maps.Marker({ 
     map: map, 
     position: results[0].geometry.location 
    }); 

    } else { 
    try { 
     console.error("Geocode was not successful for the following reason: " + status); 
    } catch(e) {} 
    } 
}); 
</script>

您应该能够初始化纬度地图/经度如下：https://developers.google.com/maps/documentation/javascript/tutorial#MapOptions
