将地理编码器结果保存到数组 - Closure Trouble

问题描述

好吧，所以我有一段时间寻找这个问题的解决方案，但我没有发现任何具体的。
在您指向Google的服务条款之前，请阅读问题的结尾！

Okay, so I have searched a while for a solution to this problem, but I have found nothing specifically on this.And before you point me to Google's Terms of Service, please read to the ende of the question!

所以这里的想法：
我想使用Google的Geocoder将地址的纬度和经度保存到数组中。我设法正确计算所有的值，但我只是不能把它保存到数组。我已经使用一个匿名函数传递地址到函数，但保存仍然不工作。请帮助！

So here's the idea:I want to save the Latitude and Longitude of an address into an array using Google's Geocoder. I managed to calculate all the values correctly, but I just can't seem to save it to the array. I have already used an anonymous function to pass the address to the function, but the saving is still not working. Please help!

关于Google的服务条款：我知道我不能将此代码保存在任何地方，不能在Google地图中显示。但我需要将其保存为kml文件，以便以后导入Google地图。我知道，这将是更方便的只是创建地图，但由于其他原因是不可能的。

Regarding Google's Terms of Service: I know that I may not save this code anywhere and not display it in a Google Map. But I need to save it as a kml-file to feed into a Google Map later. I know, it would be much more convenient to just create the Map, but for other reasons that's not possible.

adressdaten []是一个包含地址数据的二维数组
这是代码：

adressdaten[] is a two-dimensional array with the data of the addressesThis is the code:

for (i=1; i<adressdaten.length-1; i++)  {
//Save array-data in String to pass to the Geocoder
var adresse = adressdaten[i][3] + " " + adressdaten[i][4];
var coordinates;
var geocoder = new google.maps.Geocoder();
    geocoder.geocode( { 'address': adresse}, (function (coordinates, adresse) {
        return function(results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
               var latLong = results[0].geometry.location;
               coordinates = latLong.lat() + "," + latLong.lng();


        } else {
                alert('Geocode was not successful for the following reason: ' + status);
            }
        }
    })(coordinates, adresse));
    adressdaten[i][6] = coordinates;
}

推荐答案

地理编码是异步的。

类似（未测试）

更新为使用函数闭包

function geocodeAddress(address, i) {
  geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
       var latLong = results[0].geometry.location;
       coordinates = latLong.lat() + "," + latLong.lng();
       adressdaten[i][6] = coordinates;
    } else {
       alert('Geocode of '+address+' was not successful for the following reason: ' + status);
    }
  });
}

var geocoder = new google.maps.Geocoder();
for (i=1; i<adressdaten.length-1; i++)  {
  //Save array-data in String to pass to the Geocoder
  var adresse = adressdaten[i][3] + " " + adressdaten[i][4];
  var coordinates;
  geocodeAddress(addresse, i);

}
