//获取指定参数，返回字符串;
2、request.QueryStrings();
//获取全部参数，并返回数组;
3、request.setQuery("参数","参数的值");
//如果当前地址栏有此参数，那么将更新此参数，否则返回一个新的地址栏参数字符串。
例如：
当前地址栏参数字符串为：?name=a&site=never_online
alert(request.setQuery("name","blueDestiny"))
如果地址栏参数中有"name"，那么返回?name=blueDestiny&site=never_online
setQuery方法有自动追加参数的功能。如：
当前地址栏参数字符串为：?site=never_online
alert(request.setQuery("name","blueDestiny"))
则返回?site=never_online&name=blueDestiny
同理，如果地址栏没有参数，也会自动追加参数
alert(request.setQuery("name","blueDestiny"))
返回?name=blueDestiny
