Cookies
1:功能：保存一小块数据2:常用Cookies属性：expires,path,domain,secure
3:写入Cookies:格式 name=value
4:用escape编码，unescape解码
5:用obj.setTime(obj.getTime+60*1000)设置过期时间
6:cookie保存的数据不能超过4000bytes
7:cookie读取的时候用indexOf,substring,或者split
JS操作cookies
<HTML>
<SCRIPT LANGUAGE="JavaScript">
function Set(){
var Then = new Date()
Then.setTime(Then.getTime() + 60*1000 ) //60秒
document.cookie = "Cookie1=测试数据;expires="+ Then.toGMTString()
}
function Get(){
var cookieString = new String(document.cookie)
var cookieHeader = "Cookie1="
var beginPosition = cookieString.indexOf(cookieHeader)
if (beginPosition != -1){
document.all.Textbox.value = cookieString.substring(beginPosition
+ cookieHeader.length)
}
else
document.all.Textbox.value = "Cookie 未找到!"
}
</SCRIPT>
