第 2个redirect如果只有个参数时就是简单重定向当有2个或以上参数时就能动态指定目url该可用于翻页功能比如 redirect("http://www.xxx.com/list.asp?page=1","page="+parseInt(request("page"))+1)还可用于url类型搜索如:redirect("http://www.xxx.com/search.asp","range="+escape($("range").value),"keyword="+escape($("keyword").value))url操作变得简单起来
redirect 核心是建立个url参数表(hash table)第 2个及以后参数都是添加到该hash table中最后把该表序列化为目url
刚发完日志就想到可以再改进下增加个参数决定是否用新窗口打开目url

根据昨天临下班前想法再修改下把第 2个参数放到最后面去
/*
Use Age:
redirect(url,[paras_1],[paras_2],...,[paras_n],[Win])
paras_n: url参数形式如 page=1 或 type=s 等
Win: 最后个参数布尔类型为true时用新窗口(window.open)打开url否则用当前窗口(location.open)打开默认值为 false
Example:
redirect("http://www.google.com/search","q=hello","start=20",true); //将在google搜索"hello"并翻到第3页并用新窗口打开
redirect("http://www.xxx.com/listpage.asp","page="+parseInt(request("page"))+1); //翻页功能中“下页”
