JSON解析Bing地图响应

Question

我想解析出使用Bing地图的反向地理位置。

http://www.microsoft.com/maps/isdk/ajax/ 查找信息>反向查找

如果你在看代码，当你查找地址，你把它恢复

if (typeof closeDependency !== 'undefined') {

我目前使用的代码解析“名称”进入它的部分，以便我可以在其他地方使用它。

function GetResults(locations) { 
    if (locations) { 
     for (var i = 0; i < locations.length; i++) { 
      s = locations[i].Name; 
      // 
      var addressSplit = s.split(", "); 
      addresscode = addressSplit[0] 
      citycode = addressSplit[1] 
      statezip = addressSplit[2] 
      country = addressSplit[3] 
      var statezipSplit = statezip.split(" "); 
      statecode = statezipSplit[0]; 
      zipcode = statezipSplit[1]; 
      var loc_array = new Array(); 
      loc_array[0] = addresscode; 
      loc_array[1] = citycode; 
      loc_array[2] = statecode; 
      loc_array[3] = zipcode; 
      window.locationArray = loc_array; 
     } 
    } 

我想更改上面的代码，以使用具有地址线，位置，postaltown等已经部分。

Answer 1

function GetResults(locations) { 
    var locations = locations.Results; 
    if (locations) { 
     for (var i = 0; i < locations.length; i++) { 
      var addr = locations[i].Address, 
       loc_array = new Array() 
       addresscode, citycode, country, statecode, zipcode; 
      // 
      addresscode = addr.AddressLine; 
      citycode = addr.Locality; 
      country = addr.CountryRegion; 
      statecode =addr.AdminDistrict; 
      zipcode = addr.PostalCode; 
      loc_array[0] = addresscode; 
      loc_array[1] = citycode; 
      loc_array[2] = statecode; 
      loc_array[3] = zipcode; 
      window.locationArray = loc_array; 
     } 
    } 

这会做你想做的。但这不是很好的做法。首先 - 如果你有多个地点，每个地点都会覆盖另一个地点。其次，这会污染不推荐的窗口命名空间。

Answer 2

看起来您已经将“Results”对象作为“locations”参数传递给函数，所以我将在该假设下工作。您可以参考位置[i] .Address，而不是参考位置[i] .Name。这会给你一个应该拥有你需要的所有属性的对象。

function GetResults(locations) { 
    if (locations) { 
    for (var i = 0; i < locations.length; i++) { 
     var s = locations[i].Address; 
     // 
     var address = s.AddressLine; 
     var city = s.Locality; 
     var state = s.AdminDistrict; 
     var zip = s.PostalCode; 
     var country = s.CountryRegion 

     // and so on... 
    } 
    } 

}

你需要做的唯一的事情就是改变你的loc_array线：

function GetResults(locations) { 
    var s, location; 
    if (locations) { 
     for (var i = 0; i < locations.length; i++) { 
      s = locations[i].Name; 
      location = locations[i]; 
      // 
      var loc_array = []; 
      loc_array[0] = location.Address.AddressLine; 
      loc_array[1] = location.Address.Locality; 
      loc_array[2] = location.Address.AdminDistrict; 
      loc_array[3] = location.Locations.Coordinates.Latitude; 
      loc_array[4] = location.Locations.Coordinates.Longitude; 
      // ... 
      window.locationArray = loc_array; 
     } 
    } 
}
