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,
------解决方案--------------------页面调用该文件了?
------解决方案--------------------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
