在一个页面中把内容写入cookie中，在另一个页面中获得并显示在页面中（在safari和firefox上可以但在chrome 上不可以，不知道为什么。）
第一个页面：点击按钮把表单内容写入cookie，

<script type="text/javascript">
//写cookie
function writeCookie(name, value, hours){
var expire = "";
if(hours != null){
expire = new Date((new Date()).getTime() + hours * 3600000);
expire = "; expires=" + expire.toGMTString();
}
document.cookie = name + "=" + escape(value) + expire;
}
//获得cookie
function getCookie(Name)
{
var search = Name + "=" ;
if(document.cookie.length > 0)
{
offset = document.cookie.indexOf(search)
if(offset != -1)
{
offset += search.length
end = document.cookie.indexOf(";", offset)
if(end == -1) end = document.cookie.length
return unescape(document.cookie.substring(offset, end))
}
else return "";
}
}
//点击如片获得cookie
function getName(){
var button=document.getElementById("button");
var inhtml=document.getElementById("inhtml");
button.onclick=function(){
var name=getCookie("username") ;
inhtml.innerHTML=name;
}
}
//点击提交写入cookie
function add(){
var connect=document.getElementById("connect");
alert(connect.value);
writeCookie("username", connect.value,24);
}
</script>
</head>
<body onload="getName();">
</body>
<form onsubmit="add();">
<input type="text" id="connect"/>
<input type="submit" value="提交" />
</form>
<span id="inhtml"></span>

<body>
</body>
</html>
