问题描述
我一直在使用PhoneGap的创建了一个简单的移动应用。

$.each(jsonObj.Marker, function(){

var mark = {

}

});
for(var i=0; i< markers.length; i++){
var maddress = markers[i].location;
var image = markers[i].icon;
var custname = markers[i].title;
geocodeAddress(maddress, image, custname,map);
}
});
function geocodeAddress(maddress, image, custname,map) {
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': maddress}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var myLatlng = new google.maps.LatLng(results[0].geometry.location.lat(),results[0].geometry.location.lng());
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var marker = new MarkerWithLabel({
position: myLatlng, map:map, icon: image,labelContent: custname,
labelAnchor: new google.maps.Point(22, 0),
labelClass: "labels", // the CSS class for the label
labelStyle: {opacity: 0.75}});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
function initialize() {
var chicago = new google.maps.LatLng(35.442579,-40.895920);
var mapOptions = {
zoom: 4,
center: chicago,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"></div>
</body>
</html>
