该教程纯属娱乐，无任何实际作用哈，就是博主觉得很有意思额。

当访客离开我们网站页面时，变换其原来的浏览器标签，可吸引用户继续点击浏览，哈哈，你懂的。

教程很简单，将下面的 js 放入 footer 即可。教程完毕！

<script>
window.onload = function() {
    function c() {
        document.title = document[a] ? "草榴技术讨论區欢迎您，" + str + "好 !": d
    }
    hour = (new Date).getHours(),
    str = "",
    str = 6 > hour ? "凌晨": 9 > hour ? "早上": 12 > hour ? "上午": 14 > hour ? "中午": 17 > hour ? "下午": 19 > hour ? "傍晚": 22 > hour ? "晚上": "夜里",
    a = document.title,
    b = document.title,
    d = document.title,
    "undefined" != typeof document.hidden ? (a = "hidden", b = "visibilitychange") : "undefined" != typeof document.mozHidden ? (a = "mozHidden", b = "mozvisibilitychange") : "undefined" != typeof document.webkitHidden && (a = "webkitHidden", b = "webkitvisibilitychange"),
    "undefined" == typeof document.addEventListener && "undefined" == typeof document[a] || document.addEventListener(b, c, !1)
}; 
</script>
