使用谷歌地图API v3，我如何获得给定地址的LatLng？

问题描述

如果用户输入地址，我想转换为相应的LatLng。

If a user inputs an address, I want to convert to the equivalent LatLng.

我读过文档，我想我可以使用Geocoder类这样做，但无法弄清楚如何实现它。

I've read the documentation, and I think I can use the Geocoder class to do this, but can't figure out how to implement it.

感谢您的帮助！

推荐答案

缩短一点：

geocoder = new google.maps.Geocoder();

function codeAddress() {

    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = document.getElementById( 'address' ).value;

    geocoder.geocode( { 'address' : address }, function( results, status ) {
        if( status == google.maps.GeocoderStatus.OK ) {

            //In this case it creates a marker, but you can get the lat and lng from the location.LatLng
            map.setCenter( results[0].geometry.location );
            var marker = new google.maps.Marker( {
                map     : map,
                position: results[0].geometry.location
            } );
        } else {
            alert( 'Geocode was not successful for the following reason: ' + status );
        }
    } );
}
