Anyone know Javascript?

**Jiggles** · 29-06-2009, 08:55 PM

I keep getting an error with this script:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<style type="text/css">
td { font-size:0.6em; } /* temporary for testing purposes */
#NowOn {
border: 2px solid red;
font-size: 1.5em;
color: red;
background: yellow;
height: 200px;
width: 400px;
}
</style>

<script type="text/javascript">

/* NOT CURRENTLY USED
var thedate = new Date();
var dayofweek = thedate.getDay();
var hourofday = thedate.getHours();

*/

// Sun=0 1 2 3 4 5 Sat=6
var DayOfWeek = new Array('Weekend','Monday','Tuesday','Wednesday','Th ursday','Friday','Weekend');

var NoShow = 'No Show Scheduled<br />for KSWH';
var DH = new Array (7);
for (d=0; d<7; d++) {
DH[d] = new Array (24);
for (h=0; h<24; h++) { DH[d][h] = ''; }
}

<?php include ('times.html') ?>
// Add more when schedule is known. Note: there may be better ways to do this when information is known.

function NowON() {
var thedate = new Date();
var dayofweek = thedate.getDay();
var hourofday = thedate.getHours();
var showOn = DH[dayofweek][hourofday];
if (showOn == '') { showOn = '<p />No Show Currently Scheduled for KSWH'; }
document.getElementById('NowOn').innerHTML = showOn;
}
</script>
</head>
<body>
<div id='NowOn'><script type="text/javascript"> document.write(NowON())</script></div>
</body>
</html>

It works but it keeps adding "undefined" to the end of the out put.

the PHP include content is:

DH[1][12] = 'No Show Name<br>with DJ JT<br>Monday at Noon<hr>No Genre';

DH[5][13] = 'The Em and Tag Show<br>with Em and Tag<br>Friday at 1 PM<br>Rock';
DH[5][14] = 'No Show Name<br>with DJ Kevin<br>Friday at 3 PM<br>No Genre';
DH[5][15] = 'Big Hamptons Block<br>with Big Hampton<br>Friday 4 to 6 PM<br>Rap';
DH[5][16] = 'Big Hamptons Block<br>with Big Hampton<br>Friday at 5 PM<br>Rap';
DH[5][22] = 'Rockin till Midnight<br>with DJ Werewolf<br>Friday 10 to Midnight<br>Rock';
DH[5][23] = 'Rockin till Midnight<br>with DJ Werewolf<br>Friday at 11 PM<br>Rock';

This is for a LEGAL radio station with all the licences.

Thanks

This line should have another quotation mark -

if (showOn == ''")

Not sure about this line either.. how does it know to print the php variable? You can't put an echo around it either because that would mess up the javascript variables that are added in.

var showOn = DH[dayofweek][hourofday];

Oh, and the include file is a html one? So how is it setting those as PHP variables?

Personally, I'd do it either all in javascript or all in PHP, mixing the two is complicated and doesn't really serve any purpose.

It's already closed, it's actually two single quotes (') in Callum's code.

I think Callum has included the html file with PHP for simpler editing, i.e. if other scheduled times are to be added then it's just a case of editing that file rather than the main one. It's only been included using PHP, it's content can be anything. In this case it's just more javascript code and is included in the main file as such. Other than the <?php include ('times.html') ?> line, there's no PHP at all.

Javascript is client side and PHP is server side. Some things can be done with Javascript only, and others with PHP. And some things can be done by combining the two. For example, if Callums show times were held in a database and he wanted to access that using PHP, the included file could have PHP code to pull the data from the database and write javascript variable definitions for each one.

Anyway. Back to the OP, I gave it a quick scan and nothing obvious popped out. I'll have a closer look but this line should have a (

in it: -

<div id='NowOn'><script type="text/javascript"> document.write(NowON());</script></div>

I had a closer look and apart from a space inside "Th ursday", it's fine.

Since you're using a PHP include in there, though, remember main file MUST have a .php extension

Still hasn't worked

This was the only thing like it that I could find on the net! Plus I don't have a good knowledge of PHP to do in that.

This is the same idea of what I get as an output:

Auto DJ is now on. 2 hour loop of tunes!

undefined <----This is what's bugging me!

It's definitely OK, it worked on my test server no problem.

Is this on my server, Callum?

Local WAMP. It was fine then I saved it came back to it and it gave me the undefined error!

Even on my own server its like that:

Ah, sorry I thought you meant it wasn't working at all. I get the "undefined line" too. Should be easy enough to take out...I'll be back.

P.S. Thanks for letting me know you moved that domain! It's always handy to be able to cancel dead accounts...

**Jiggles** · 04-07-2009, 10:06 AM

Sorry for forgetting to tell you.

I was concentrating so much on moving all my sites I forgot about that one. Sorry!

Thanks for taking a look.

}

</script>
</head>
<body>
<div id='showBox'></div>
<script type="text/javascript">ReplaceDivContent('showBox');</script>
</body>
</html>

Probably better to put something along the lines of "enable javascript to see show details" inside the DIV by default, this will get replaced anyway.
