ie does not support canvas tag. when u use excanvas.js it gives an error object doesn't support this property or method ( excanvas.js )

<canvas id="someid"></canvas> this works in firefox , google chrome but not in ie.

the solution is:

<div id="insertCanvas"></div>

<script type="text/javascript">
// new canvas element
var canvasElem = document.createElement('canvas');
// you need to add canvasElem to the document before doing anything else.
document.getElementById("insertCanvas").appendChild(canvasElem);
// if it is IE...
if (typeof G_vmlCanvasManager != 'undefined') {
// you've to reassign the variable to the new element created by initElement
canvasElem = G_vmlCanvasManager.initElement(canvasElem);
}
canvasElem.setAttribute("id","analiz");
// now you can do getContext on this canvasElem...
</script>
