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");

Hi!

Just wanted to know if it could be possible to add a bower.json file, then adding ignore rules to it.

This way, it will be possible to fetch only the JS file without getting tests, HTML files, etc.

What do you think @arv?

In your canvas polyfill , it only support canvas drawImage from image, but i want to drawImage by passing the source canvas directly ? How to solve it ?

i want to use make a image and append in my dom, but not work in IE8. what's the problem?
...
var image = canvas.toDataURL("image/png");
var img = document.createElement("img");
img.src = image;
img.width = canvas.width;
img.height = canvas.height;
$("#id").append(img);
...

It appears that the script fails to load when using Trident/IE web browser control. The errors occurs at

In Trident, MSIE is not defined in the user agent and the return value for the match function is null. I'm not sure the IE_VERSION variable is used anywhere and maybe it can be removed.

It would be nice to add a tag with the version to fix in the bower.json file.

Why get the Canvas object is [object DispHTMLUnknownElement] type, the following code:

var els = doc.getElementsByTagName('canvas');
      for (var i = 0; i < els.length; i++) {
        this.initElement(els[i]); //[object DispHTMLUnknownElement]
      }
}

initElement: function(el) {
     //...
     el.innerHTML = '';//throws an exception under IE8
     //...
}

In the right circumstances, it should be [ object DispHTMLGenericElement ].

Why is this so?TKS

IE6 cannot to load script. It's support IE6?
