用Cookie实现仅弹出一次窗口(JavaScript)


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()">
