我在一个网站上看到了这个返回代码,我正在尝试在我的网站上使用它。我无法理解其中的 toURl 和 refUrl 是如何生成的。请指导他们的结构。谢谢
var backtriggered = false;
setTimeout('goBack()',timer);
function goBack() {
if(backtriggered) return false;
backtriggered = true;
toURL=getWelcomeCookie('toURL');
refURL = getWelcomeCookie('refURL');
var reg = /(.*)\/sites\/(.*)\/(\d{4})\/(\d{2})\/(\d{2})\/(.*)\/?/;
if(reg.test(toURL) == false){
document.cookie="toURL"+ "=" +escape(toURL)+";path=/; domain=.mycsnippets.com; expires=Thu, 01-Jan-1900 00:00:01 GMT";
document.cookie="refURL"+ "=" +escape(toURL)+";path=/; domain=.mycsnippets.com; expires=Thu, 01-Jan-1900 00:00:01 GMT";
}
location.href=toURL;
}
