如何使用Google地图将地址代码为经纬度

问题描述

我希望能够在谷歌地图上绘制几家公司，并理解我需要对这些公司进行地理编码。

我还在代码下面显示了该图的多个标记一个地图。

我如何对几个公司地址进行地理编码（使用以下地址作为第一个示例）并将其合并到当前的代码中？

我真的需要别人的帮助，因为我无法理解Google文档以及将其与我已有的文档整合。

解决方案

您可以使用 Google地理编码获得你的邮政编码的坐标编辑：我不是很喜欢你改变这种问题的感觉，但确定。请尝试像这样（未测试）：

  //创建一个包含坐标的数组
 / /纽约，旧金山和西雅图
 var places = []; 
 
 //为每个城市添加一个LatLng对象
 //places.push(new google.maps.LatLng（40.756，-73.986））; 
 //places.push(new google.maps.LatLng（37.775，-122.419））; 
 //places.push(new google.maps.LatLng（47.620，-122.347））; 
 //places.push(new google.maps.LatLng（-22.933，-43.184））; 
 var result; 
 var xmlhttp = new XMLHttpRequest（）; 
 xmlhttp.open（GET，http://maps.googleapis.com/maps/api/geocode/json?address=your+code&sensor=false\",true）; 
 xmlhttp.onreadystatechange = function（）{
 if（xmlhttp.readyState == 4）{
 result = eval（'（'+ xmlhttp.responseText +'）'）; 
 if（result.status ==OK）{
 var location = new google.maps.LatLng（result.results [0] .geometry.location.lat，result.results [0]。 geometry.location.lng）; 
 places.push（位置）; 
  

尽管可能出现小错误，但这应该可行。

EDIT2：我刚才发现更简单的解决方案

a>：

  //创建一个包含坐标

 var places = []; 
 
 //为每个城市添加一个LatLng对象
 //places.push(new google.maps.LatLng（40.756，-73.986））; 
 //places.push(new google.maps.LatLng（37.775，-122.419））; 
 //places.push(new google.maps.LatLng（47.620，-122.347））; 
 //places.push(new google.maps.LatLng（-22.933，-43.184））; 
 var geocoder = new google.maps.Geocoder（）; 
 geocoder.geocode（{'address'：your + code}，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 
 //}）; 
 places.push（results [0] .geometry.location）; 
} else {
 alert（Geocode was not成功的原因如下：+ status; 
} 
}）; 
  

I want to be able to plot several companies on a google map and understand I need to geocode these.

I also have the code below that plot's multiple markers on a map.

How can I Geocode several company addresses (using the following address as the first example) and incorporate it into the current code I have?

I really need someone's help as I can't make sense of the Google documentation as well as incorporating it with what I already have.

解决方案

you could use google's geocoding to obtain coordinates of your post codes

EDIT: I don't really like you changing the sense of the question like that but ok. Please try sth like that (its not tested):

// Creating an array that will contain the coordinates
// for New York, San Francisco, and Seattle
var places = [];

// Adding a LatLng object for each city
//places.push(new google.maps.LatLng(40.756, -73.986));
//places.push(new google.maps.LatLng(37.775, -122.419));
//places.push(new google.maps.LatLng(47.620, -122.347));
//places.push(new google.maps.LatLng(-22.933, -43.184));
var result;
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "http://maps.googleapis.com/maps/api/geocode/json?address=your+code&sensor=false",true);
 xmlhttp.onreadystatechange=function() {
  if (xmlhttp.readyState==4) {
       result = eval('(' + xmlhttp.responseText + ')');
if (result.status == "OK") {
var location = new google.maps.LatLng(result.results[0].geometry.location.lat, result.results[0].geometry.location.lng);
places.push(location);

this should probably work, despite possible minor errors.

EDIT2: I have just now found simpler solution:

// Creating an array that will contain the coordinates
// for New York, San Francisco, and Seattle
var places = [];

// Adding a LatLng object for each city
//places.push(new google.maps.LatLng(40.756, -73.986));
//places.push(new google.maps.LatLng(37.775, -122.419));
//places.push(new google.maps.LatLng(47.620, -122.347));
//places.push(new google.maps.LatLng(-22.933, -43.184));
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': "your+code"}, 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
    //});
    places.push(results[0].geometry.location);
  } else {
    alert("Geocode was not successful for the following reason: " + status);
  }
});
