我已经写了一些javascript来调用信息,并为数据文件'latlngtrunc.js'中的每个条目放置一个带有自定义图标的标记。
latlngtrunc.js包含'product','result','level'&每个条目'posn'。有3个不同的“级别”,我想将它们表示为不同颜色的图标。
使用注释行时,以下代码可以正常工作:
var marker = new GMarker(posn);
并按预期显示通用标记(无自定义图标)。当我用以下内容替换它时:
var marker = new GMarker({map:map, posn:posn, icon:icon.icon, shadow:icon.shadow});
根本不显示任何标记。
两个警报:
alert(icon.icon);
alert(icon.shadow);
正确返回图片网址,因此我非常确定所有信息都是从外部'latlngtrunc.js'文件中正确检索的。
非常感谢任何帮助!

最终的简单解决方案。我需要将'Anchor'属性添加到'var customIcons'以便它们显示:
var customIcons = {
risk: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_green.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png',
iconAnchor: new GPoint(0,0),
infoWindowAnchor: new GPoint(0,0)
},
threat: {
image: 'http://labs.google.com/ridefinder/images/mm_20_orange.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png',
iconAnchor: new GPoint(0,0),
infoWindowAnchor: new GPoint(0,0)
},
fraud: {
image: 'http://labs.google.com/ridefinder/images/mm_20_red.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png',
iconAnchor: new GPoint(0,0),
infoWindowAnchor: new GPoint(0,0)
}
};
(0,0)的锚点略微偏移图像,因此需要摆弄以正确定位。
