我遵循了本教程http://www.mobiledevelopersolutions.com/home/start/twominutetutorials/tmt4part1,但我遇到了一个问题。地理位置在默认的 Android 浏览器上不起作用。它适用于 Chrome、IE 和 Android 版 Chrome。但不是默认的 Android 浏览器。
我想我必须把 { enableHighAccuracy: true } 放在我无法弄清楚的地方。
这是代码:
var mapdata = { destination: new google.maps.LatLng(51.3704888, 6.1723862) };
// Home page
$('#page-home').live("pageinit", function() {
$('#map_square').gmap(
{ 'center' : mapdata.destination,
'zoom' : 12,
'mapTypeControl' : false,
'navigationControl' : false,
'streetViewControl' : false
})
.bind('init', function(evt, map) {
$('#map_square').gmap('addMarker',
{ 'position': map.getCenter(),
'animation' : google.maps.Animation.DROP
});
});
$('#map_square').click( function() {
$.mobile.changePage($('#page-map'), {});
});
});
function fadingMsg (locMsg) {
$("<div class='ui-overlay-shadow ui-body-e ui-corner-all fading-msg'>" + locMsg + "</div>")
.css({ "display": "block", "opacity": 0.9, "top": $(window).scrollTop() + 100 })
.appendTo( $.mobile.pageContainer )
.delay( 2200 )
.fadeOut( 1000, function(){
$(this).remove();
});
}
//Create the map then make 'displayDirections' request
$('#page-map').live("pageinit", function() {
$('#map_canvas').gmap({'center' : mapdata.destination,
'mapTypeControl' : true,
'navigationControl' : true,
'navigationControlOptions' : {'position':google.maps.ControlPosition.LEFT_TOP}
})
.bind('init', function() {
$('.refresh').trigger('tap');
});
});
$('#page-map').live("pageshow", function() {
$('#map_canvas').gmap('refresh');
});
// Request display of directions, requires jquery.ui.map.services.js
var toggleval = true; // used for test case: static locations
$('.refresh').live("tap", function() {
// START: Tracking location with device geolocation
if ( navigator.geolocation ) {
fadingMsg('Using device geolocation to get current position.');
navigator.geolocation.getCurrentPosition (
function(position ) {
$('#map_canvas').gmap('displayDirections',
{ 'origin' : new google.maps.LatLng(position.coords.latitude, position.coords.longitude),
'destination' : mapdata.destination, 'travelMode' : google.maps.DirectionsTravelMode.DRIVING},
{ 'panel' : document.getElementById('dir_panel')},
function (result, status) {
if (status === 'OK') {
var center = result.routes[0].bounds.getCenter();
$('#map_canvas').gmap('option', 'center', center);
$('#map_canvas').gmap('refresh')
} else {
alert('Unable to get route');
}
}
);
},
function(){
alert('Unable to get location');
$.mobile.changePage($('#page-home'), { });
});
} else {
alert('Unable to get location.');
}
// END: Tracking location with device geolocation
$(this).removeClass($.mobile.activeBtnClass);
return false;
});
// Go to map page to see instruction detail (zoom) on map page
$('#dir_panel').live("tap", function() {
$.mobile.changePage($('#page-map'), {});
});
// Briefly show hint on using instruction tap/zoom
$('#page-dir').live("pageshow", function() {
fadingMsg("Tap any instruction<br/>to see details on map");
});
谢谢你的帮助!
