HTML5无需SSL连接的地理定位

HTML 5地理定位用于确定用户的位置。这可以在没有SSL连接的情况下进行。可以按照以下方式生成−

// Variable apigeo shows successful location:
var apigeo = function(position) {
   alert("API geolocation success!lat = " + position.coords.latitude + "lng = " + position.coords.longitude);
};
var tryapigeo = function() {
   jQuery.post( "check the location on google map", function(success) {
      apiGeolocationSuccess({coords: {latitude: success.location.lat, longitude: success.location.lng}});
   }) //Gives success on given geolocation
   .failure(function(err) { //On failure, alert with failure is shown
      alert("error while showing geolocation! "+err);
   });
};

然后可以生成错误代码的各种开关情况，不同的错误有不同的错误代码。

var tryloc = function() {//tryloc variable show current position
if (navigator.geolocation) {
   navigator.geolocation.getCurrentPosition(
      browserGeolocationSuccess, browserGeolocationFail,{
      maximumAge: 70000, timeout: 40000, enableHighAccuracy: true});
   / /this will show result with high accuracy
}};
