你的浏览器居然不支持Canvas？！赶快换一个吧！！

window.onload = function(){
var canvas = document.getElementById("canvas");
canvas.width = 800;
canvas.height = 600;
var context = canvas.getContext("2d");
// 实例1: 圆形端点,斜角连接,在画布左上角
context.beginPath();
context.moveTo(0,0);
context.lineTo(180,0);
context.lineTo(180,180);
context.lineJoin = ‘bevel’;
context.lineCap = ’round’;
context.lineWidth = 10;
context.strokeStyle = "red";
context.stroke();
// 实例2: 圆形端点,斜角连接,不在画布左上角
context.beginPath();
context.moveTo(300,200);
context.lineTo(480,200);
