Cookied Popups

Oftentimes, webmasters have a desire to launch a popup when someone comes to their website. However, they don't want it to pop up for that same person each and every time the visitor arrives. Below is a nice little script we found that will launch a popup and cookie the visitor to prevent it from popping again for a predetermined length of time.

You can set the time variable in the script from 0 (pop up all the time) to whatever number of days you would like. The cookie that is set will ensure that the popup will act the way you set it. You will then have control over the frequency at which any particular visitor sees the popup. This script could be used if you have a mailing list and want to remind visitors to join, or you can run an advertisement through it, or what have you. The possibilities are limited only by your imagination.

<!--Two steps to installing this script--> <!--1) Copy everything below, and paste in BODY section of page--> <!--2) Configure variables below to customize popup--> <SCRIPT LANGUAGE="JavaScript"> /* This script compliments of http://www.designerindex.com */ var expDays = 1; // number of days the cookie should last (0 will cause it to always pop up) var page = "http://www.YourPopUpPageAddressHere"; var windowprops = "width=650,height=500,location=yes,toolbar=no,menubar=no,scrollbars=yes,resizable=yes"; function GetCookie (name) { var arg = name + "="; var alen = arg.length; var clen = document.cookie.length; var i = 0; while (i < clen) { var j = i + alen; if (document.cookie.substring(i, j) == arg) return getCookieVal (j); i = document.cookie.indexOf(" ", i) + 1; if (i == 0) break; } return null; } function SetCookie (name, value) { var argv = SetCookie.arguments; var argc = SetCookie.arguments.length; var expires = (argc > 2) ? argv[2] : null; var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null; var secure = (argc > 5) ? argv[5] : false; document.cookie = name + "=" + escape (value) + ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) + ((domain == null) ? "" : ("; domain=" + domain)) + ((secure == true) ? "; secure" : ""); } function DeleteCookie (name) { var exp = new Date(); exp.setTime (exp.getTime() - 1); var cval = GetCookie (name); document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString(); } var exp = new Date(); exp.setTime(exp.getTime() + (expDays*24*60*60*1000)); function amt(){ var count = GetCookie('count') if(count == null) { SetCookie('count','1') return 1 } else { var newcount = parseInt(count) + 1; DeleteCookie('count') SetCookie('count',newcount,exp) return count } } function getCookieVal(offset) { var endstr = document.cookie.indexOf (";", offset); if (endstr == -1) endstr = document.cookie.length; return unescape(document.cookie.substring(offset, endstr)); } function checkCount() { var count = GetCookie('count'); if (count == null) { count=1; SetCookie('count', count, exp); window.open(page, "", windowprops); } else { count++; SetCookie('count', count, exp); } } window.onload=checkCount </script>
