嘎嘎，一处笔误，最内层滴 for 后面多了分号！！！
L@_@K
for(var p in list)
{
for(var c in list[p])
{
for( var d in list[p][c] ); // 都是分号惹滴祸!
{
s.push(d);
}
}
}去掉分号就欧了！
var s = [];for(var p in list)
{
document.write(p,"<br />");
for(var c in list[p])
{
document.write(" ",c,"<br />");
for(var d in list[p][c])
{
document.write(" ",d,"<br />");
s.push(d);
}
}
}
alert(s);
L@_@K
for(var p in list)
{
for(var c in list[p])
{
for( var d in list[p][c] ); // 都是分号惹滴祸!
{
s.push(d);
}
}
}去掉分号就欧了！
var s = [];for(var p in list)
{
document.write(p,"<br />");
for(var c in list[p])
{
document.write(" ",c,"<br />");
for(var d in list[p][c])
{
document.write(" ",d,"<br />");
s.push(d);
}
}
}
alert(s);
后面的;号去掉。
第一轮省的for in是没问题的，后面几轮都会报错
for(city in cities)
{
_self.city.options.add(new Option(city,cities[city].city_id));
}
{
_self.city.options.add(new Option(city,cities[city].city_id));
}
少了var？
debugger是JS用来触发调试用的，和加断点差不多
测试代码如下
L@_@K
var s = [];
debugger;var cities = list["山西省"];for(var city in cities)
{
//_self.city.options.add(new Option(city,cities[city].city_id));
s.push(city);
}
alert(s);
我也奇怪，我上面的测试代码一切没问题TO:jol_boy
我用sarari,firefox,opera都测试过，完全没问题，就IE会报这错误，真是郁闷了……

只要代码没有错，一般都能正确执行，
不过不同浏览器滴js引擎在解释js代码时确实存在细微差别！
