在 Google Maps API 中使用地址而不是经度和纬度 [英] Using Address Instead Of Longitude And Latitude With Google Maps API
问题描述
我听说可以提交地址而不是经度和纬度，这对我的系统来说更可行.用户必须在创建他们的个人资料时输入他们的地址，然后他们的个人资料将显示他们家的谷歌地图.我目前的 Google Maps API 与经度和纬度完美配合:
I've heard that it is possible to submit an Address instead of Longitude and Latitude and this would be much more feasible for my system. The user has to input their address when creating their profile and their profile afterwards will then display a Google Maps of their house. I currently have the Google Maps API working perfectly with Longitude and Latitude:

zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
var marker = new google.maps.Marker({
position: new google.maps.LatLng(52.640143,1.28685),
map: map,
title: "Mark On Map"
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>

请有人帮助我更改我的代码，以便它使 Google Maps API 能够在其位置请求地址，因为我想直接从 mySQL 数据库中读取用户的地址.
Please could somebody assist me to alter my code so that it enables the Google Maps API to request an Address in its place because I want to read the Address of the user directly from mySQL database.
推荐答案
参见这个例子，将地图初始化为San Diego, CA".
See this example, initializes the map to "San Diego, CA".
使用 Google Maps Javascript API v3 Geocoder 将地址转换为坐标可以显示在地图上.
Uses the Google Maps Javascript API v3 Geocoder to translate the address into coordinates that can be displayed on the map.

工作代码片段:
var geocoder;
var map;
var address = "San Diego, CA";
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
if (geocoder) {
geocoder.geocode({
'address': address
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (status != google.maps.GeocoderStatus.ZERO_RESULTS) {
map.setCenter(results[0].geometry.location);
var infowindow = new google.maps.InfoWindow({
content: '<b>' + address + '</b>',
size: new google.maps.Size(150, 50)
});
var marker = new google.maps.Marker({
position: results[0].geometry.location,

});
}
