Address:
<input id="searchTextField" type="text" size="50" style="text-align: left;width:357px;direction: ltr;">
<br>
            latitude:<input name="latitude" class="MapLat" value="" type="text" placeholder="Latitude" style="width: 161px;" disabled>
            longitude:<input name="longitude" class="MapLon" value="" type="text" placeholder="Longitude" style="width: 161px;" disabled>
    <div id="map_canvas" style="height: 350px;width: 500px;margin: 0.6em;"></div>

您可能想看看此示例的fillInAddress()方法。除其他详细信息外，它还将更新文档中的postal_code输入字段。

可能最相关的是 fillInAddress() for 循环中的if语句：

if (componentForm[addressType]) {
  var val = place.address_components[i][componentForm[addressType]];
  document.getElementById(addressType).value = val;
}

当 place.address_components[i] 等于 "postal_code" 时，它将继续将 place.address_components[i][componentForm[addressType]] 的值放在名为 val 的 var 中。这将返回邮政编码的short_name。
