Question

I am developing a new website that needs the ability to detect if the user has visited the website previously, then direct them to a specific URL (i.e. example.com/welcomeback.html) if they have.

I assume that this needs to be done with the usage of cookies and javascript, but I can’t find any tutorials on this anywhere.

The help is much appreciated. Thank you.

Answer 1

function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}

gets cookie

function getCookie(c_name)
{
   var i,x,y,ARRcookies=document.cookie.split(";");
   for (i=0;i<ARRcookies.length;i++)
    {
       x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
          y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
          x=x.replace(/^\s+|\s+$/g,"");
          if (x==c_name)
          {
              return unescape(y);
          }
    }
 }

if(getCookie('visited'))
{
 location.href="redirecturl";
}else
{
setCookie('visited',1,365);
}
