//写cookies函数 作者:翟振凯
function SetCookie(name,value)//两个参数,一个是cookie的名子,一个是值
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)//取cookies函数
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}
function delCookie(name)//删除cookie
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
SetCookie ("xiaoqi", "3")
//alert(getCookie('xiaoqi'));
</script>
<input type="button" value="reflesh" onclick="reflesh();"/>
<select id="times" onchange="changeCookiesTimes();">
<option value="5">5</option>
<option value="10">10</option>
<option value="15">15</option>
</select>
<input type="checkbox" value="1" id="chooseAuto" name="chooseAuto" onclick="changeState();" />
<script>
var isAutoCookie = getCookie('isAutoCookie');
var cookieTimes = getCookie('cookieTimes');
var nowTimes = document.getElementById("times");
var isAuto = true;
var chooseAuto = document.getElementById("chooseAuto");
alert(chooseAuto.checked);
if (cookieTimes == null) {
SetCookie ("cookieTimes", nowTimes.value)
alert(getCookie('cookieTimes'));
} else {

}
function changeCookiesTimes() {
alert('nowTimes='+nowTimes.value);

}
}
function changeState() {

}
document.getElementById("times").value = cookieTimes;

}
function reflesh(){

是写错了。是做直播的时候,自动设置刷新当前的页面的,如设置隔多长时间自动刷新一次页面好获取新的直播内容。也能设置成手动刷新方式,就是有个控制开关。

reflesh好像写错了,是refresh。这程序是干什么用的啊?
