[解决办法]
代码太长，就没有你对问题的描述？
[解决办法]
var XmlRoot = DOM.documentElement;
XmlRoot.childNodes[0];
[解决办法]
XmlRoot.childNodes[0].nodeValue;
[解决办法]
程序有问题
if(requestType== "north ")
{
listNorthStates();
}
else if(requestType== "All ")
{
listAllStates();
}
这个感觉条件好怪。
还有，请用DOM直接读取，不要用XMLHTTP，无需多此1举创建多个对象
var xmlDoc = new ActiveXObject( "Microsoft.XMLDOM ");
xmlDoc.load(ServerUrl + "city.xml?dd= " + Date());
