I Need "Help" with Syntax Error

rsines · 09-21-2011, 04:04 PM

I've been searching the web trying to find a way to redirect based on a date range, I've not found the exact code, but as much as I can make out this should be pretty close. Could someone tell me why I keep getting an error?

<script type="text/javascript">
function newLocation()
{
var today = new Date();
var daynum = today.getDOY();

if (daynum => 243 && daynum <= 283) {window.location("my.html")}
else {window.location("your.html")}
}
</script>:

Hi rsines

Code:

<script type="text/javascript">
function newLocation()
{
   var today = new Date();
   var daynum = today.getDOY();

   if ((daynum => 243)&&(daynum <= 283))
   {
     window.location.href = "my.html";
   }
   else 
   {
      window.location.href = "your.html";
   }
}
</script>

I still get the syntax error. I admit I didn't try seperating the conditions that way though. I've added semicolons brackets, everything I've seen done on the web but I still get the error. Thanks for the help

also try this: ( http://www.w3schools.com/js/js_comparisons.asp )

Code:

function newLocation()
{
var today = new Date();
var daynum = today.getDOY(); 

if (daynum >= 243 && daynum <= 283) {
	window.location("my.html")
	}
else {
	window.location("your.html")
	}
}
</script>

Thanks for "reading" the answers

You didnt use my code

the main fix in my code was this:

Code:

window.location("your.html")

should be this:

Code:

window.location.href = "your.html";

The code I provided, was yours but fixed.

It's still window.location.href ... but where is your getDOY() defined? It's not a javascript standard. Try to add this

Code:

Date.prototype.getDOY = function() {
   var onejan = new Date(this.getFullYear(),0,1);
   return Math.ceil((this - onejan) / 86400000);
}

THANK YOU! THANK YOU! THANK YOU!

It now works:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Page Redirect</title>

<script type="text/javascript">

Date.prototype.getDOY = function() {
var onejan = new Date(this.getFullYear(),0,1);
return Math.ceil((this - onejan) / 86400000);
}

function newLocation()
{
var today = new Date();

var daynum = today.getDOY();

if (daynum >= 243 && daynum <= 283) {
window.location = "my.html";
}
else {
window.location = "your.html";
}
}
</script>

</head>
<body>

<center>
<form>
<input type="button" value="Click me!" onclick="newLocation()" />
</form>
</center>

</body>
</html>
