Hi, I'm trying to set up a javascript function to hide a particular <div> after a visitor has viewed once by using a cookie (and setting a 24-hour expiry on this). Here is the code so far, which is not yet working... can anybody help me here, please? What am I doing wrong? Cheers, Martin <html> <head> <script type = "text/javascript"> function createCookie(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 + "="+ value + expires + "; path=/"; // available throughout the directory } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } function eraseCookie(name) { createCookie(name,"",-1); // set cookie to expire on previous day } </script> </head> <body onload = 'readCookie("listoffercookie"); createCookie("listoffercookie", "12345", 1")'> <script type = "text/javascript"> if (document.cookie.indexOf("listoffercookie")!=-1) { document.getElementById('listoffer').style.visibility = 'hidden'; } </script> <div id="listoffer"> <p>My content...</p> </div> </body> </html>
