<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);
}
};
