轉別人的js（二）高級運用--d

【9、終極應用--彈出的窗口之cookie控制】
回想一下，上面的彈出窗口雖然酷，但是有一點小毛病(沉浸在喜悅之中，一定沒有發現吧？)比如你將上面的腳本放在一個需要頻繁經過的頁面裏(例如首頁)，那麼每次刷新這個頁面，窗口都會彈出一次，是不是非常煩人？:-(有解決的辦法嗎？yes! ;-) follow me.
我們使用cookie來控制一下就可以了。
首先，將如下代碼加入主頁面html的<head>區：
<script>
function openwin()
{window.open("page.html","","width=200,height=200"}
function get_cookie(name)
{var search = name + "="
var return＆#118alue = "";
if (documents＆#46cookie.length > 0) {
offset = documents＆#46cookie.indexof(search)
if (offset != -1) {
offset += search.length
end = documents＆#46cookie.indexof(";", offset);
if (end == -1)
end = documents＆#46cookie.length;
return＆#118alue=unescape(documents＆#46cookie.substring(offset,end))
}
}
return return＆#118alue;
}
function loadpopup(){
if (get_cookie('popped')==''){
openwin()
documents＆#46cookie="popped=yes"
}
}
</script>
然後，用<body >（注意不是openwin而是loadpop啊！）替換主頁面中原有的<body>這一句即可。你可以試着刷新一下這個頁面或重新進入該頁面，窗口再也不會彈出了。真正的pop-only-once！
