首先说一下业务需求：

需要在当前各主流浏览器上从tab标签形式弹出一个页面，尽量不要以单独窗口弹出。

下面是网上搜集并修改、验证后的js代码，以备以后参阅。

function getUnionCookie(B) {var A = new RegExp(B + "=([^;]+)"), _ = A.exec(document.cookie), $ = "";if (_ != null) {try {$ = decodeURI(_[1]);}catch (C) {}}return $;
}function setUnionCookie(sName, sValue, oExpires, sPath) {document.cookie = sName + "=" + escape(sValue) + ";expires=" + oExpires.toUTCString() + ";path=" + sPath;
}//使用cookie控制每隔24小时弹一次，似乎不见效
function updateunionli() {var exp2 = new Date();exp2.setTime(exp2.getTime() + 24 * 60 * 60 * 1000);setUnionCookie("unionli_lc", 4 + 1, exp2, '/');var poped_statist = new Image();poped_statist.src = "http://www.anmeiqi.com/logo/anmeiqi.gif"; //广告的统计的url
