获取用户的地理位置（zipcode）并在页面加载期间显示它 [英] Fetch the user's geo location (zipcode) and display it during page load
问题描述
我需要获取用户的地理位置（ZipCode）并在页面加载期间显示它。目前我通过2个帖子实现了这个目标，有没有办法在一个帖子中实现。
谢谢
我尝试过：
函数ShowMessages（）{
if（navigator。地理定位）{
navigator.geolocation.getCurrentPosition（成功）;
}否则{
alert（当前不支持地理位置）浏览器！）;
}
功能成功（位置）{
调试器;
var lat = position .coords.latitude;
var lng = position.coords.longitude;
var latlng = new google.maps.LatLng（lat，lng）;
var geocoder = geocoder = new google.maps.Geocoder（）;
geocoder.geocode（{'latLng'：latlng}，function（results，status）{
if（status == google.maps.GeocoderStatus.O K）{
if（results [1]）{
var searchAddressComponents = results [0] .address_components，
searchPostalCode =;
$ .each（searchAddressComponents，function（）{
if（this.types [0] ==postal_code）{
searchPostalCode = this.short_name;
}
}）;
文件.getElementById（'hidden1'）。value = searchPostalCode
__doPostBack（''，''）;
}
}
}）;
}
}
I need to fetch the user's geo location (ZipCode) and display it during page load. Currently I am achieving this by 2 post backs, is there any way to achieve within a single post back.
Thanks
What I have tried:
function ShowMessages() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success);
} else {
alert("Geo Location is not supported on your current browser!");
}
function success(position) {
debugger;
var lat = position.coords.latitude;
var lng = position.coords.longitude;
var latlng = new google.maps.LatLng(lat, lng);
var geocoder = geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'latLng': latlng }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[1]) {
var searchAddressComponents = results[0].address_components,
searchPostalCode = "";
$.each(searchAddressComponents, function () {
if (this.types[0] == "postal_code") {
searchPostalCode = this.short_name;
}
});
document.getElementById('hidden1').value = searchPostalCode
__doPostBack('', '');
}
}
});
}
}
推荐答案
.each（searchAddressComponents，function（）{
if（this.types [0] ==postal_code）{
searchPostalCode = this.short_name;
}
}）; < br $>
document.getElementById（'hidden1'）。value = searchPostalCode
__doPostBack（''，''）;
}
}
}）;
}
}
.each(searchAddressComponents, function () {
if (this.types[0] == "postal_code") {
searchPostalCode = this.short_name;
}
});
document.getElementById('hidden1').value = searchPostalCode
__doPostBack('', '');
}
}
});
}
}
