简单的例子：
<script>
function test(){
document.cookie = "name="+document.form1.txt1.value
alert(document.cookie)
}
</script>
<form name=form1>
<input name=txt1>
<input type=button onclick="test()" value=测试>
</form>

创建cookie之后，最好用完后删除

给你个例子：

<script>
function setCookie(name, value, expire) {
document.cookie = name + "=" + escape(value) + ((expire == null) ? "" : ("; expires=" + expire.toGMTString()))
}
function getCookie(Name) {
var search = Name + "="
if (document.cookie.length > 0) {
// if there are any cookies
offset = document.cookie.indexOf(search)
if (offset != -1) {
// if cookie exists
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset)
// set index of end of cookie value
if (end == -1)
end = document.cookie.length
return unescape(document.cookie.substring(offset, end))
}
}
}
function register(name) {
var today = new Date()
var expires = new Date()
expires.setTime(today.getTime() + 1000*60*60*24*365)
setCookie("TheCoolJavaScriptPage", name, expires)
}
</script>
<BODY><H1>Register Your Name with the Cookie-Meister</H1><P>
<SCRIPT>
var yourname = getCookie("TheCoolJavaScriptPage")
if (yourname != null)
document.write("<P>Welcome Back, ", yourname)
else
document.write("<P>You haven't been here in the last year...")
</SCRIPT>
<P> Enter your name. When you return to this page within a year, you will be greeted with a personalized greeting. <BR>
<FORM onSubmit="return false">
Enter your name: <INPUT TYPE="text" NAME="username" SIZE= 10><BR>
<INPUT TYPE="button" value="Register" onClick="register(this.form.username.value); history.go(0)">
</FORM>
