我正在尝试在我的计算机上测试一些地理定位代码,但我甚至无法运行这些示例.
虽然当我尝试从我的计算机打开html文件时它们完全从文档网站运行,但我得到一个空白页面,我所做的只是试图检测我的位置……

var map;
function initialize() {
var myOptions = {

map = new google.maps.Map(document.getElementById('map_canvas'),myOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {

var infowindow = new google.maps.InfoWindow({
map: map,position: pos,content: 'Location found using HTML5.'

map.setCenter(pos);
},function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service Failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,position: new google.maps.LatLng(60,105),content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window,'load',initialize);
</script>
</head>
<body>
<div id="map_canvas"></div>

请帮忙,你能找出我做错了什么吗？
