Question

我发现这个很棒的脚本可以根据经度和纬度找到用户的邮政编码。通过阅读代码，我发现必须有一个状态ID才能使信息变得可见。我的问题是，是否可以将信息的cookie放入状态ID中。所以它会根据这个人放一个邮政编码，我想制作一个该邮政编码的cookie，以便在我的网站上进一步使用它。它使用地理定位并将信息插入谷歌并获取邮政编码。所以我想抓住那个邮政编码并尽可能地创建一个cookie。任何帮助将不胜感激。感谢。

假设您的代码正确检索el.short_name中的邮政编码，您可以在检索后立即存储该值：

这是一个创建cookie的功能：

function createCookie(name,value,days) {
    var expires = "", date;
    if (days) {
        date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires=" + date.toGMTString();
    }
    document.cookie = name+"="+value+expires+"; path=/";
}

以下是getZipCode的修改版本，它在检索邮政编码后立即写入cookie：

  getZipCode: function(position){
     var position = position.coords.latitude + "," + position.coords.longitude;
     $.getJSON('proxy.php',{
        path : "http://maps.google.com/maps/api/geocode/json?latlng="+position+"&sensor=false",
        type: "application/json"
     }, function(json){
        //Find the zip code of the first result
        if(!(json.status == "OK")){
           GETZIP.error('Zip Code not Found');
           return;
        }
        var found = false;
        $(json.results[0].address_components).each(function(i, el){
           if($.inArray("postal_code", el.types) > -1){
              $("#status").text(Your zip code: + el.short_name);
              createCookie("zipcode", el.short_name, 365);
              found = true;
              return;
           }
        });
        if(!found){
           GETZIP.error('Zip Code not Found');
        }
     });
  }

从ID创建Cookie？
