图片自找

window.onload=function(){
var context = document.getElementById('canvas').getContext('2d')

/*
context.createPattern(img'repeat-style');
repeat-style参数可以是：
'no-repeat' 不重复
'repeat' x，y轴重复
'repeat-x' x轴重复
'repeat-y' y轴重复

扩展：context.createPattern(img'repeat-style')方法参数：
可以是image图片作为参数，
可以是canvas对象作为参数
可以是video视频对象作为参数

总结：context.fillStyle 可以等于以下参数
color 
gradient
image
canvas
video;

var image1 = new Image();
image1.src = '1.png';
image1.onload = function(){
var pattern = context.createPattern(image1,'repeat');
context.fillStyle=pattern;
context.fillRect(0,0,800,800);
