IE8和移动浏览器的HTML5地理位置
|
因此，我一直在开发Web应用程序，并且已经实现了HTML5地理位置功能。我使用取自Google网站的Javascript代码实现了这一点，该Javascript代码还与我在页面上拥有的Google Map进行了交互。这是下面的代码：
// Note that using Google Gears requires loading the Javascript
// at http://code.google.com/apis/gears/gears_init.js
var initialLocation;
var siberia = new google.maps.LatLng(60, 105);
var newyork = new google.maps.LatLng(40.69847032728747, -73.9514422416687);
var browserSupportFlag = new Boolean();
function initialize() {
var myOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById(\"map_canvas\"), myOptions);
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
browserSupportFlag = true;
navigator.geolocation.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeolocation(browserSupportFlag);
});
// Try Google Gears Geolocation
} else if (google.gears) {
browserSupportFlag = true;
var geo = google.gears.factory.create(\'beta.geolocation\');
geo.getCurrentPosition(function(position) {
initialLocation = new google.maps.LatLng(position.latitude,position.longitude);
map.setCenter(initialLocation);
}, function() {
handleNoGeoLocation(browserSupportFlag);
});
// Browser doesn\'t support Geolocation
} else {
browserSupportFlag = false;
handleNoGeolocation(browserSupportFlag);
}
function handleNoGeolocation(errorFlag) {
if (errorFlag == true) {
alert(\"Geolocation service failed.\");
initialLocation = newyork;
} else {
alert(\"Your browser doesn\'t support geolocation. We\'ve placed you in Siberia.\");
initialLocation = siberia;
}
map.setCenter(initialLocation);
}
}
sensor=true
