Just watch and learn.
可以通过以下方法, 测试浏览器是否支持HTML5：
创建一个test.html文件
<!DOCTYPE> <html> <head> <meta charset="gbk"/> <title>测试浏览器是否支持HTML5</title> <script language="javascript"> function test() { try{ document.createElement("canvas").getContext("2d"); document.getElementById("support").innerHTML="HTML5 Canvas is supported in your browser"; }catch(e){ document.getElementById("support").innerHTML="HTML5 Canvas is not supported in your browser"; } } </script> </head> <body onLoad="test()"> <p id="support"></p> </body> </html>上面的代码试图创建一个canvas 对象，并且获取上下文，如果发生异常，则可以捕获错误,判断是否支持HTML5
