Cut & Paste Time Controlled Popunder Window

Credit: JavaScript Kit

Description: This versatile popunder window script allows you to precisely control how often the window pops under, in terms of "once every x hours". For example, specifying 24 hours translates into the script popping under only once a day. Furthermore, you can modify this duration at anytime, and the script will reset itself to the new duration (ie: 8 hours instead). Cool!

Be kind to your visitors, and use this script to tame your popunder window!

Example: In this example, the popunder window only displays itself once every 24 hours, randomly choosing from a list of URLs to show each time.

Directions: Insert the below script into the <HEAD> section of your page:

<script type="text/javascript"> //Time controlled Pop-under window- By JavaScriptKit.com //This credit notice must stay intact for use //Visit http://www.javascriptkit.com for this script and 400+ more! //1) specify URLs to randomly select from and pop-under: //To display a single URL, just remove all but the first entry below: var popunder=new Array() popunder[0]="http://www.freewarejava.com" popunder[1]="http://www.dynamicdrive.com" popunder[2]="http://www.webmasterpick.com" popunder[3]="http://www.codingforums.com" //2) specify popunder window features //set 1 to enable a particular feature, 0 to disable var winfeatures="width=800,height=510,scrollbars=1,resizable=1,toolbar=1,location=1,menubar=1,status=1,directories=0" //3) Control frequency of the pop up: //"always", for every time page loads OR //"x hours" for once per x hours, where x is an integer (ie: 12 hours) var popfrequency="24 hours" ///No editing beyond here required///// function get_cookie(Name) { var search = Name + "=" var returnvalue = ""; if (document.cookie.length > 0) { offset = document.cookie.indexOf(search) if (offset != -1) { // if cookie exists offset += search.length // set index of beginning of value end = document.cookie.indexOf(";", offset); // set index of end of cookie value if (end == -1) end = document.cookie.length; returnvalue=unescape(document.cookie.substring(offset, end)) } } return returnvalue; } function resetcookie(){ var expireDate = new Date() expireDate.setHours(expireDate.getHours()-10) document.cookie = "tcpopunder=;path=/;expires=" + expireDate.toGMTString() } function loadornot(){ if (get_cookie('tcpopunder')==''){ loadpopunder() var expireDate = new Date() expireDate.setHours(expireDate.getHours()+parseInt(popfrequency)) document.cookie = "tcpopunder="+parseInt(popfrequency)+";path=/;expires=" + expireDate.toGMTString() } } function loadpopunder(){ win2=window.open(popunder[Math.floor(Math.random()*(popunder.length))],"",winfeatures) win2.blur() window.focus() } if (popfrequency=="always"){ resetcookie() loadpopunder() } else{ if (get_cookie('tcpopunder')!=parseInt(popfrequency)) resetcookie() loadornot() } </script>
