HTML5 canvas 游戏无法在 IE 中运行

Question

I'm working on a HTML5 canvas game using a JavaScript library called Propulsionjs.com. The preview can be seen here: http://druls.com/balloon/ . To enable the canvas element in IE I have included a few of libraries like extcanvas, still some part of the game is not working properly.

<!--[if IE]>
<script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->

<script type="text/javascript" src="excanvas.js"></script>

Can anyone help me out? As I found out sprite elements are not working. Can anyone help me solving this issue? The source code here: http://druls.com/balloon/balloons.zip .

Answer 1

Because on line 1567: value.call(value,value);

value is undefined and IE9 is stopping execution.
