一个IP一天只弹一次代码

function register(name) {
  var today = new Date();
  var expires = new Date();
  expires.setTime(today.getTime() + 1000*60*60*24);
  setCookie("wangzhongwangluo", name, expires);
}

var exitURL="http://www.wangzhongwangluo.com";

function openWin() {

var c = getCookie("wangzhongwangluo");
  if (c != null) {
    return;
  }
  register("9free");
  
  var featureStr="''";
  
    featureStr="'top=0,left=0,width=800,height=600,toolbar=yes, menubar=no, scrollbars=no, resizable=no, location=no, status=no,center:no'";

self.focus();
  
  var ExitWindow = window.open(exitURL,'', featureStr);
  
    ExitWindow.focus();
  
}

openWin();
window.focus()
