creat a canvas by javascript

[zhao-ping]

when I create a canvas by javascript , it show me 'object unsupport“getContext” ' on IE8

my code like that
var canvas = document.createElement("canvas"); var ctx = canvas.getContext("2d");

If you have created your canvas element dynamically it will not have the getContext method added to the element. To get it working you need to call initElement on the G_vmlCanvasManager object.

var el = document.createElement('canvas');
G_vmlCanvasManager.initElement(el);
var ctx = el.getContext('2d');
Thats it. Now you can use the HTML5 spec for Canvas as your reference.
