谷歌地图v3对象为空或未定义

我收到“无法获取属性的值'3'：对象为空或未定义”在IE7和IE8的这行代码中，并且不知道如何解决它。任何帮助不胜感激。谷歌地图v3对象为空或未定义

marker = new google.maps.Marker

我不知道undefined是什么意思，因为我在前面的代码块中声明了变量。任何帮助，不胜感激... HTTP：//jsfiddle.net/svuce/1/

这条线如何：var infowindow = new google.maps.InfoWindow（）; - 那样有用吗？ –

错误可能来自您正在标记构造函数中的其中一个参数 - 现在尝试对它们进行硬编码 –

获取你的数组的最后一个部分的结尾去掉后面的逗号，这会在IE中导致错误：

['Maroubra Beach', 'Some text goes here<br />text', 'cycling', -33.950198, 151.259302],
