我想使用foreignobject元素在画布上绘制HTML文本,在MDN中我可以看到以下链接(参见参考资料),这在Chrome和Mozilla浏览器中工作正常,但在IE10中没有,我使用的是IE10。

浏览器模式:IE10&文件模式:标准

参考: https://developer.mozilla.org/en/docs/HTML/Canvas/Drawing_DOM_objects_into_a_canvas

错误:

DOM7000: Access Denied. Resource access is restricted for cross-origin URL: 'blob:7C72C95F-3E3F-4CD6-804C-C2D8CCC06283'.

以下是代码段: -

            <!DOCTYPE html>
            <html>
            <body>
            <p><canvas id="canvas" style="border:2px solid black;" width="200" height="200"></canvas>
            <script>
            var canvas = document.getElementById("canvas");
            var ctx = canvas.getContext("2d");
            var data = "<svg xmlns='http://www.w3.org/2000/svg' width='200' height='200'>" +
                         "<foreignObject width='100%' height='100%'>" +
                           "<div xmlns='http://www.w3.org/1999/xhtml' style='font-size:40px'>" +
                             "<em>I</em> like <span style='color:white; text-shadow:0 0 2px blue;'>cheese</span>" +
                           "</div>" +
                         "</foreignObject>" +
                       "</svg>";
            var DOMURL = self.URL || self.webkitURL || self;
            var img = new Image();
            var svg = new Blob([data], {type: "image/svg+xml;charset=utf-8"});
            var url = DOMURL.createObjectURL(svg);
            img.onload = function() {
                ctx.drawImage(img, 0, 0);
                DOMURL.revokeObjectURL(url);
            };
            img.src = url;
            </script>
            </body>
            </html>

您可以尝试使用Chromeframe,但看起来他们明年将退休:(
