AJAX automatic page refresh (with php pages)

For the timer, use window.setInter val(). If you get stuck, post your code.

Well, you see:

I'm using a javascript function in the <head>, to write to the <canvas> tag.
The tutorial I link to, see above, uses getElementById, but <script> doens't support an id (I think?).
...so how do I reload the data into the head?

This is a part of the <head>, and <body>:

Code:

    	<?php
			// displayPageType_game -> 475
			// this is where the javascript is loaded that writes to the <canvas> tag...
			$canvasId = "gameBoard";
			$canvasSize = 475;
			$dotSize = 3;
			$lineSize = 1;
			$lineColor = "#bbbbbb";
			$radiusPixAdjust = -1;
			$extraBorder = 1;
			displayBoard($gameid, $canvasSize, $canvasId, $dotSize, $lineSize, $lineColor, $radiusPixAdjust, $extraBorder);
		?>
</head>
<body onLoad="canvasDraw();">

... and here is the canvas:

Code:

            <canvas id="<?php echo $canvasId;?>" width="<?php echo $canvasSize;?>" height="<?php echo $canvasSize;?>">
            You are using a browser that doesn't support the &lt;canvas&gt; tag.
            </canvas>

A script tag can have an ID. There's no JavaScript in the code that you posted above. Post that too.

Note: If you set the src of a script tag, it will execute the code within the source file.
