从地理编码结果中获取城市？ [英] get city from geocoder results?

问题描述

item.formatted_address有效，但不是item.address_components.locality？

  geocoder.geocode（{'address'：request.term}，function（results，status）{
 
 response（$。map （item.formatted_address ++ item.address_components.locality）
} 
}）; 
  

//返回的数组为：

 results：[
 {
address_components：[
 {
long_name：London，
short_name：London，
types：[locality，political] 
}]，
formatted_address：英国伦敦威斯敏斯特//数组的其余部分... 
  
 
 
 $ b 
 
 
解决方案 
  var arrAddress = item.address_components; 
 var itemRoute =''; 
 var itemLocality =''; 
 var itemCountry =''; 
 var itemPc =''; 
 var itemSnumber =''; 
 
 //遍历address_component数组
 $ .each（arrAddress，function（i，address_component）{
 console.log（'address_component：'+ i）; 
 
 if（address_component.types [0] ==route）{
 console.log（i +：route：+ address_component.long_name）; 
 itemRoute = address_component.long_name; 
 
 
 if（address_component.types [0] ==locality）{
 console.log（town：+ address_component.long_name）; 
 itemLocality = address_component.long_name; 
} 
 
 if（address_component.types [0] ==country）{
 console.log（country：+ address_component.long_name ）; 
 itemCountry = address_component.long_name; 
} 
 
 if（address_component.types [0] ==postal_code_prefix）{
 console.log（pc ：+ address_component.long_name）; 
 itemPc = address_component.long_name; 
} 
 
 if（address_component.types [0] ==street_nu mber）{
 console.log（street_number：+ address_component.long_name）; 
 itemSnumber = address_component.long_name; 
} 
 // return false; //打破循环
}）; 
  
 
Having problems getting the different arrays content from geocoder results.

item.formatted_address works but not item.address_components.locality?
geocoder.geocode( {'address': request.term }, function(results, status) {

        response($.map(results, function(item) {

        alert(item.formatted_address+" "+item.address_components.locality)
    }            
}); 
// the array returned is;
 "results" : [
      {
         "address_components" : [
            {
               "long_name" : "London",
               "short_name" : "London",
               "types" : [ "locality", "political" ]
            } ],
          "formatted_address" : "Westminster, London, UK" // rest of array...
any help appreciated!

Got this working in the end using:
var arrAddress = item.address_components;
var itemRoute='';
var itemLocality='';
var itemCountry='';
var itemPc='';
var itemSnumber='';

// iterate through address_component array
$.each(arrAddress, function (i, address_component) {
    console.log('address_component:'+i);

    if (address_component.types[0] == "route"){
        console.log(i+": route:"+address_component.long_name);
        itemRoute = address_component.long_name;
    }

    if (address_component.types[0] == "locality"){
        console.log("town:"+address_component.long_name);
        itemLocality = address_component.long_name;
    }

    if (address_component.types[0] == "country"){ 
        console.log("country:"+address_component.long_name); 
        itemCountry = address_component.long_name;
    }

    if (address_component.types[0] == "postal_code_prefix"){ 
        console.log("pc:"+address_component.long_name);  
        itemPc = address_component.long_name;
    }

    if (address_component.types[0] == "street_number"){ 
        console.log("street_number:"+address_component.long_name);  
        itemSnumber = address_component.long_name;
    }
    //return false; // break the loop   
});
