Question

我有以下谷歌地图代码：

<script type="text/javascript"> 
function initialize() { 
var mapOptions = { 
center: new google.maps.LatLng(-27.444916,153.03), 
zoom: 12, 
disableDefaultUI: true,
keyboardShortcuts: false,
mapTypeId: google.maps.MapTypeId.ROADMAP 
}; 
var map = new google.maps.Map(document.getElementById("map_canvas"), 
mapOptions); 
setMarkers(map, beaches); 
} 
var beaches = [
['Car:806', -27.4481025666613, 153.035155217002, 916],
['Car:520', -27.4777186625335, 153.00697421394, 915],
['Car:1477', -27.4523199466005, 153.029570366226, 914],
['Car:815', -27.5315143182514, 153.023819055977, 913],
['Car:334', -27.3930054770139, 153.104887341157, 912],
['Car:191', -27.4705744176833, 153.030243260862, 911],
...

['Car:618', -27.4146792620242, 153.081801794924, 1],
['Car:1096', -27.3369540394594, 153.069279763313, 0],
];
function setMarkers(map, locations) { 
var image = new google.maps.MarkerImage('http://labs.google.com/ridefinder/images/mm_20_orange.png', 
new google.maps.Size(20, 32), 
new google.maps.Point(0,0), 
new google.maps.Point(0, 32)); 
var shadow = new google.maps.MarkerImage('http://labs.google.com/ridefinder/images/mm_20_shadow.png', 
new google.maps.Size(37, 32), 
new google.maps.Point(0,0), 
new google.maps.Point(0, 32)); 
var shape = { 
coord: [1, 1, 1, 20, 18, 20, 18 , 1], 
type: 'poly' 
}; 
for (var i = 0; i < locations.length; i++) { 
var beach = locations[i]; 
var myLatLng = new google.maps.LatLng(beach[1], beach[2]); 
var marker = new google.maps.Marker({ 
position: myLatLng, 
map: map, 
shadow: shadow, 
icon: image, 
shape: shape, 
title: beach[0], 
zIndex: beach[3] 
}); 
} 
} 
</script>

它在chrome和IE中运行良好，但在IE中我得到一个错误。这一切对我来说都很好，但我很想知道为什么我会收到这个错误：

对第996行的引用是：

var myLatLng = new google.maps.LatLng(beach[1], beach[2]);

我认为IE不喜欢调用数组中的索引。我只是想知道是否有不同的方法来做到这一点？

IE不喜欢“悬挂逗号”（数组或对象末尾的逗号，后面没有任何内容）。它们导致它在对象或数组的末尾附加一个null，然后在API中生成错误。

从代码中删除它们。

var beaches = [
['Car:806', -27.4481025666613, 153.035155217002, 916],
