Trouble link to external JS
hi,
i'm working through http://www.w3schools.com/html/html5_canvas.asp . want create seperate js rather include within html doc , can't examples work within seperate js. doesn't show of js. doing wrong?
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>html5 canvas</title>
<script type="text/javascript" src="js/game.js"></script>
</head>
<body>
<canvas id="mycanvas" width="200" height="100" style="border:1px solid #c3c3c3;">
your browser not support html5 canvas tag.
</canvas>
</body>
</html>
game.js
// javascript document
// original w3c code...didn't work! var c=document.getelementbyid("mycanvas");
var mycanvas = document.getelementbyid("mycanvas");
var ctx=c.getcontext("2d");
ctx.fillstyle="#ff0000";
ctx.fillrect(0,0,150,75);
it doesn't work because external javascript file linked page before document object model (dom) loaded. javascript file trying use document.getelementbyid("mycanvas") before element id created.
put line before closing </body> tag:
<script type="text/javascript" src="js/game.js"></script>
then should work.
