javascript - 用于动态创建 Canvas 元素的 Excanvas

Question

Excanvas“for enternet Explorer”对于预定义的 Canvas 元素工作正常。但是当涉及到在脚本中动态创建canvas元素时，就不行了...

有什么想法吗？？

来自 the documentation :

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');
