判断浏览器是否支持canvas,具体代码如下:
<!DOCTYPE html> <head> <meta charset=utf-8 /> <title>canvas</title> <script type='text/javascript'> window.onload = function(){ /**判断浏览器是否支持canvas**/ try{ document.createElement('canvas').getContext('2d'); var addDiv = document.createElement('div'); addDiv.innerHTML='支持canvas'; document.body.appendChild(addDiv); }catch(e){ var addDiv = document.createElement('div'); addDiv.innerHTML='浏览器不支持canvas'; document.body.appendChild(addDiv); } }; </script> </head> <body> </body> </html>
