新发现一个骗链接的方法(js读取cookies)

<SCRIPT language=javascript>
function createc(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+escape(value)+expires+"; path=/";
}
function readc(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return unescape(c.substring(nameEQ.length,c.length));
}
return null;
}
function showc(name) {
value = readc(name);
if ((value == null) || (value == "null")) return "";
return value;
}
function addc(name,value,days) {
if (readc(name) != null) {
var oldvalue = readc(name);
var newvalue = oldvalue+","+value;
}
else var newvalue = value;
createc(name,newvalue,days);
}
