脚本说明: 第一步:把如下代码加入<head>区域中 <SCRIPT language="JavaScript"> <!-- function openpopup(){ window.open("welcome.htm","","width=300,height=300") } function get_cookie(Name) { var search = Name + "=" var returnvalue = ""; if (document.cookie.length > 0) { offset = document.cookie.indexOf(search) if (offset != -1) { // if cookie exists offset += search.length // set index of beginning of value end = document.cookie.indexOf(";", offset); // set index of end of cookie value if (end == -1) end = document.cookie.length; returnvalue=unescape(document.cookie.substring(offset, end)) } } return returnvalue; } function loadpopup(){ if (get_cookie('popped')==''){ openpopup() document.cookie="popped=yes" } } //--> </SCRIPT> 第二步:把<body>中内容改为: <body bgcolor="#fef4d9" onunload="loadpopup()">
