今日写了个用cookie控制弹出窗口的小程序，记录下来，没准以后能用到
cookie.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>My JSP 'cookie.jsp' starting page</title>
</head>
<script type="text/javascript">
//获取cookie的值
function getCookie(name){
var strCookie=document.cookie;
var arrCookie=strCookie.split(";");
for(var i=0;i<arrCookie.length;i++){
var arr=arrCookie[i].split("=");
if(arr[0]==name){
return arr[1];
}
}
return "";
}
/**
这也是一个取得cookie值的方法但是较复杂
function getCookie( name )
{
var nameOfCookie = name + "=";
var x = 0;
while ( x <= document.cookie.length )
{
var y = (x+nameOfCookie.length);
if ( document.cookie.substring( x, y ) == nameOfCookie )
{
if ( (endOfCookie=document.cookie.indexOf( ";", y )) == -1 )
endOfCookie = document.cookie.length;
return unescape( document.cookie.substring( y, endOfCookie ) );
}
x = document.cookie.indexOf( " ", x ) + 1;
if ( x == 0 )
break;
}
return "";
}
**/
function ready(name)
if(getCookie(name)!="no"){ //如果cookie为name的值不为no便新开一个窗口
window.open('new.jsp','notice','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no, resizable=no,width=300,height=355');
}
</script>
<body onload="ready("notice")">
这是测试cookie的页面

2、new.html
