js文件问题
<script type="text/javascript" src="http://int.dpool.sina.com.cn/iplookup/iplookup.php? format=js"></script>
<script type="text/javascript">var province = remote_ip_info.province;if(province != '北京' && province != '广东' && province != '上海' && province != '成都' && province != '深圳' ) {window.location = "http://www.baidu.com";}</script>
这段代码是根据不同城市ip 调整到指定页面，
如何把这段js 放在一个js文件里，，
我建立一个js文件
document.write("<script type="text\/javascript" src="http:\/\/int.dpool.sina.com.cn\/iplookup\/iplookup.php? format=js"><\/script>");
var province = remote_ip_info.province;
if(province != '北京' && province != '广东' && province != '上海' && province != '成都' && province != '深圳' )
{
window.location = "http://www.baidu.com";
}
这样写 没效果，

页面调用该文件了？

楼主
document.write('<script type="text\/javascript" src="http:\/\/int.dpool.sina.com.cn\/iplookup\/iplookup.php? format=js"><\/script>');
这样写，没有阻塞页面的加载，只是发送了一个请求，接着马上就用到了
province = remote_ip_info.province，
但是这时 外链的js内容还没加载完毕，所以就没效果了。
可以 把wirte的内容
换成普通阻塞加载
<script src="">。。。</script>
或者

[解决办法]
var province = remote_ip_info.province;
//alert(province) 注释就可以了
楼主还是 搜下 js动态加载吧。
