我正在使用 json 文件中的标记创建地图，我的问题是我无法让标记显示在地图上。我可以链接一个基本的 json 文件，但是当我尝试使用数组文件时，我没有得到任何标记。我的代码是：
<script src="js/mapping.js"></script>
<script type="text/javascript">
(function () {
window.onload = function () {
// Creating a new map
var map = new google.maps.Map(document.getElementById("map"), {
center : new google.maps.LatLng(51.50746, -0.127594),
zoom : 8,
mapTypeId : google.maps.MapTypeId.ROADMAP
});
// Creating a global infoBox object that will be reused by all markers
infoBubble = new InfoBubble({
minWidth: 300,
maxWidth: 400,
minHeight: 300,
maxHeight: 400,
arrowSize: 50,
arrowPosition: 50,
arrowStyle: 2,
borderRadius: 0,
shadowStyle: 1,
}); // end Creating a global infoBox object
// Creating a global infoBox object tabs
infoBubble.addTab('Details');
infoBubble.addTab('Info');
// end Creating a global infoBox object tabs
// Custom Markers
var markers = {};
var categoryIcons = {
1 : "images/liver_marker1.png",
2 : "images/liver_marker2.png",
3 : "images/liver_marker3.png",
4 : "images/liver_marker4.png",
5 : "images/liver_marker.png",
6 : "images/liver_marker6.png",
7 : "images/liver_marker.png"
} // end Custom Markers
// Looping through the JSON data
for (var i = 0, length = json.length; i < length; i++) {
var data = json[i],
latLng = new google.maps.LatLng(data.Latitude, data.Longitude);
// Creating a marker and putting it on the map
var marker = new google.maps.Marker({
position : latLng,
map : map,
title : data.title,
icon : categoryIcons[data.category]
});
// Creating a closure to retain the correct data, notice how I pass the current data in the loop into the closure (marker, data)
(function (marker, data) {
// Attaching a click event to the current marker
google.maps.event.addListener(marker, 'click', function(e) {
//infoBubble.setContent('<b>'+data.description+'</b>'+'<br>'+data.name);
infoBubble.updateTab(0, 'Details', data.deviceOwnerName);
infoBubble.updateTab(1, 'Info', data.name);
infoBubble.open(map, marker);
map.panTo(loc);
}); // end Attaching a click event to the current marker
})(marker, data); // end Creating a closure
} // end Looping through the JSON data
}
})();
google.maps.event.addDomListener(window, 'load', initialize);
</script>
我的 json 数组文件是：

我正在尝试链接到纬度和经度，但我也希望显示 DeviceId。
任何帮助，将不胜感激。
