HTML5 Canvas標籤範例
隨著時代的進步，HTML的版本一直在進化，目前比較新的版本應該就是HTML5了，這次的HTML5針對許多標籤進行調整，當然也新增了一些標籤，主要的目的是希望可以將一些本來需要利用Flash才可以完成的互動頁面取而用HTML5來進行設計，這樣比較能減輕網頁的負載，但不管怎麼進步，其最重要的目的當然還是要網友能夠看到才行！
目前各家的瀏覽器對於HTML5的支援都不一，如果想要測試看看自己所使用的瀏覽器對HTML5的支援程度，可以到這個網址測試，馬老師針對目前的三款瀏覽器（IE9、Firefox6、Chrome13）來做了測試，IE9於HTML5中測試得到了以下的分數：
Firefox6於HTML5中測試得到了以下的分數：
Chrome13於HTML5中測試得到了以下的分數：
所以用以上的結果來看，目前是Google Chrome對於HTML5的支援最好，不過也只是拿了450分中的340而已，所以是否要全面改用HTML5來開發，還是應該要好好的斟酌一下，但是先了解HTML5能做到的功能，一定是沒問題的！以下就是馬老師針對HTML新增的畫布標籤製作的範例，不過因為瀏覽器支援的關係，必須使用Chrome觀賞才會是比較完整的功能喔！

var context;
var x = 0;
var ind;
var offset;
var photos = new Array();
for(var i=1;i<=13;i++){
var im = new Image();
im.src = "img/p" + i + ".jpg";
photos.push(im);
}
function slideshow(){
context = document.getElementById('canvas').getContext('2d');
setInterval(loop,10);
}
function loop(){
x += (slider.value - x) * 0.1;
ind = Math.floor(x/800);
offset = x % 800;
context.drawImage(photos[ind], offset, 0, 800-offset, 600, 0, 0, 800-offset, 600);
context.drawImage(photos[ind+1], 0, 0, 800, 600, 800-offset, 0, 800, 600);
}
