jquery - 谷歌地图地理编码器：返回 postal_code

Question

I'm using Jquery UI to autocomplete search for an address using Google Maps Geocoder , and when an address is selected it returns the geocode information. 这是片段：

$('#address-dropdown').autocomplete({
  //Use geocoder to fetch lat+long values from an address input using google maps API
  source: function(request, response) {
    geocoder.geocode( {'address': request.term }, function(results, status) {
      response($.map(results, function(item) {
        return {
          label: item.formatted_address,
          value: item.formatted_address,
          location: item.geometry.location,
          latitude: item.geometry.location.lat(),
          longitude: item.geometry.location.lng()
        }
      }));
    })
  },

我需要能够返回使用“postal_code”以检查它们是否居住在允许的区域内。这是一个示例输出：http ://maps.googleapis.com/maps/api/geocode/json?address=1601+Main+St+Eaton+Rapids+MI+48864&sensor=false

我如何定位 postal_code 信息？

看看我的例子：http: //jsfiddle.net/nEKMK/

o是你的对象。

if (o.results[0].address_components) {
    for (var i in o.results[0].address_components) {
        if (typeof(o.results[0].address_components[i]) === "object" && o.results[0].address_components[i].types[0] == "postal_code") {
            var result = o.results[0].address_components[i].long_name;
        }
    }
}
if (!result) {
    alert("Error, there is no postal code");
} else {
   alert(result);
}
