IE支持canvas标签
使用excanvas.js可以让IE支持Html5的canvas标签,具体用法如下:
1 <html> 2 <head> 3 <title></title> 4 <!--[if IE]> 5 <script type="text/javascript" src="excanvas.js" onload="explorercanvasload"></script> 6 <![endif]--> 7 </head> 8 <body> 9 <canvas id="canvas" width="400" height="300"></canvas>10 <script type="text/javascript">11 window.onload = function() {12 var ctx = document.getElementById("canvas").getContext("2d");13 ctx.fillRect(10, 10, 20, 20);14 };15 </script>16 </body>17 </html>需要注意一点,使用时一定要在onload之后.
