destoon实现底部添加你是第几位访问者的方法

经常会看到一些网站有类似"您是第位访客"字样的计数统计，这里我们来实现把这个统计功能添加到destoon的底部，显示"你是第几问访问者"的效果。此处的计数器与网站流量统计有区别，记录的是刷新次数，并不是真实记录访问者的IP，对于需要真正进行统计的朋友可以进一步完善代码以满足自身需求。

下面就来说一下具体的实现方法：

打开底部footer.htm的文件,找到返回首页，在后面加上这段代码：

    <script language="JavaScript">
    <!--
    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 (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 + " 个来到本站访客")
    // -->
    </script>
