Display message along with name stored in cookie

(1/1)

mdahlke:
I have a prompt box appear onLoad that asks for a persons name. I am trying to get the text in the page to say "Good Morning, 'username' ".

for the onLoad I want to use onLoad="checkCookie()" but it won't write the "message" with the name and will load a seperate page.

Basically what I am asking is how can I get the message + the name pulled from the cookie to display on the page?

var message = (depends on the time of day, Good Morning or Good Afternoon)
var username = (whatever the user puts in the prompt box)


--- Code: ---<script type="text/javascript">

var time=currentTime.getHours();

var message="Good Morning!";
if (time >= 12) {
message = "Good Afternoon!";
time = time - 12;
}
if (time == 0) {
time = 12;
}

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);
    }
  }
}

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;
}

function checkCookie()
{
var username=getCookie("username");
if (username!=null && username!="")
  {
   document.write("<h3 style='margin-top:45px;text-align:center'>" + message + " " + username + "</h3>");
  }
else
  {
  username=prompt("Please enter your name:","");
  if (username!=null && username!="")
    {
    setCookie("username",username,365);
    }
  }
}
</script>
--- End code ---

mdahlke:
I did a lot of fiddling around and basically just need to figure out why there is an undefine at the end.

I stored the checkCookie() in an external file.

Is there a better way to do the document.write so that it isn't writing the function?

Inside the function I have it do a doc.write to so I am basically doing a doc.write(doc.write(checkCookie()))

I'm going to finish this but I solved it by writing out that last sentenced....

Original Code

--- Code: ---       
<script type="text/javascript">
document.write (checkCookie())
</script>
--- End code ---

Fixed Code

--- Code: ---<script type="text/javascript">
         checkCookie()
</script>

--- End code ---
