关于javascript 验证

< script language = " javascript " type = " text/javascript " >

<!--

var subed = false ;

function check()

{

if (subed == true )

{

alert( " 信息正在发送给服务器，请不要重复提交信息！ " );

return false ;

}

if (document.byts_xajh.byts_username.value == "" )

{

alert( " 请输入用户名！ " );

return false ;

}

if (document.byts_xajh.byts_password.value == "" )

{

alert( " 请输入密码！ " );

return false ;

}

subed = true ;

}

function reg()

{

window.open( " reg.aspx " , " reg " , " height=380,width=360,left=200,top=60,resizable=no,scrollbars=auto,status=no,toolbar=no,menubar=no,location=no " );

}

function errmsg()

{

var msg = " <asp:Literal id= " byts_errormsg " runat= " server " ></asp:Literal> " ;

if (msg != "" )

{

if (msg.indexOf( " unreg| " ) == 0 )

{

if (confirm( " 该用户名还未被注册!\r\r是否立即注册? " ))

{

var reginfo = msg.split( " | " );

window.open( " reg.aspx?v= " + reginfo[ 1 ], " reg " , " height=380,width=360,left=200,top=60,resizable=no,scrollbars=auto,status=no,toolbar=no,menubar=no,location=no " );

else

关于访问文件的权限问题...http://search.youkuaiyun.com/Expert/topic/2465/2465508.xml?temp=.6590082
//*******************************************************************************************************************

写入:
HttpCookie cookie = new HttpCookie("myCookie");
cookie.Values.Add("myKey","myValue");
Response.Cookies.Add(cookie);

读取:
HttpCookie cookie = Request.Cookies["myCookie"];

Cookie的用法也和ASP中差不多。比如我们建立一个名为aspcn，值为飞刀的cookie

HttpCookie cookie = new HttpCookie["aspcn"];
cookie.Value = "飞刀";
Response.AppendCookie(cookie);

我们取出Cookie值也很简单

HttpCookie cookie = Request.Cookies["aspcn"];
cookieValue = cookie.Value;

有时候我们想在一个Cookie中储存多个信息，那也没有问题。比如我们在名为aspcn的cookie下加多个信息

HttpCookie cookie = new HttpCookie("aspcn");
cookie.Values.Add("webmaster","飞刀");
cookie.Values.Add("writer","beige");
cookie.Values.Add("LinkColor","blue");
Response.AppendCookie(cookie);

取出信息也一样简单

HttpCookie cookie = Request.Cookies["aspcn"];
value1 = cookies.Values["webmaster"];
value2 = cookies.Values["writer"];

if (this.Request.RawUrl.IndexOf("?love") != -1)

它是判断你的URL中,是否包含?love

12:37:00
RawUrl.
连接地址里有没?love，有就是非
12:38:14
如果Indexof()的值返回是-1则表示,RawUrl中不包含,?love

知道了。。。？号是匹配吗。。比如kkkklove吗是吗
(十年沧海孤剑) 12:41:33
贝壳谢谢。谢谢
12:39:05
不是匹配
12:39:31
假如是这样http://news.qq.com/a/20050115/000046.htm?love
12:39:57
并不是判断匹配不匹配的问题....
12:42:53
哦。。知道了。。那以可以写成00000046.htm?love了。。或是全部把连接都写上
12:40:15
只是判断一个URL中是否包含?love
12:40:21
懂了吗?
