页面访问次数的实现

一、第一种

<script type="text/javascript">

if (localStorage.pagecount) {

localStorage.pagecount = Number(localStorage.pagecount) + 1;

} else {

localStorage.pagecount = 1;

}

document.write("访问数: " + localStorage.pagecount + " time(s).");

</script>

二、第二种

<script>

var caution = false

function setCookie(name, value, expires, path, domain, secure) {

var curCookie = name + "=" + escape(value) +

((expires) ? "; expires=" + expires.toGMTString() : "") +

((path) ? "; path=" + path : "") +

((domain) ? "; domain=" + domain : "") +

((secure) ? "; secure" : "")

if (!caution || (name + "=" + escape(value)).length <= 4000)

document.cookie = curCookie

else

if (confirm("Cookie exceeds 4KB and will be cut!"))

document.cookie = curCookie

}

function getCookie(name) {

var prefix = name + "="

var cookieStartIndex = document.cookie.indexOf(prefix)

if (cookieStartIndex == -1)

return null

var cookieEndIndex = document.cookie.indexOf(";", cookieStartIndex + prefix.length)

if (cookieEndIndex == -1)

cookieEndIndex = document.cookie.length

return unescape(document.cookie.substring(cookieStartIndex + prefix.length, cookieEndIndex))

}

function deleteCookie(name, path, domain) {

if (getCookie(name)) {

document.cookie = name + "=" +

((path) ? "; path=" + path : "") +

((domain) ? "; domain=" + domain : "") +

"; expires=Thu, 01-Jan-70 00:00:01 GMT"

}

}

function fixDate(date) {

var base = new Date(0)

var skew = base.getTime()

if (skew > 0)

date.setTime(date.getTime() - skew)

}

var now = new Date()

fixDate(now)

now.setTime(now.getTime() + 365 * 24 * 60 * 60 * 1000)

var visits = getCookie("counter")

if (!visits)

visits = 1

else

visits = parseInt(visits) + 1

setCookie("counter", visits, now)

document.write("您是第" + visits + "客人！")

</script>
