<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> </head> <body> <canvas id="canvas" style="boder:1px solid #aaa;display:block;margin:50px auto;"> 当浏览器不支持Canvas,请更换浏览器后再试 </canvas> <script type="text/javascript"> var tangram={ {p:[{x:0,y:0},{x:800,y:0},{x:400,y:400}],color:"#caff67"}, {p:[{x:0,y:0},{x:400,y:400},{x:0,y:800}],color:"#67beef"}, {p:[{x:800,y:0},{x:800,y:400},{x:600,y:600},{x:600,y:200}],color:"#ef3d61"}, {p:[{x:600,y:200},{x:600,y:600},{x:400,y:400}],color:"#f9f5la"}, {p:[{x:400,y:400},{x:600,y:600},{x:400,y:800},{x:200,y:600}],color:"#a594c0"}, {p:[{x:200,y:600},{x:400,y:800},{x:0,y:800}],color:"#fa8ecc"}, {p:[{x:800,y:400},{x:800,y:800},{x:400,y:800}],color:"#f6ca29"}, } window.onload=function(){ var canvas=document.getElementById("canvas"); canvas.width=800; canvas.height=800; var context=canvas.getContext("2d"); for(var i=0;i<tangram.length;i++){ draw(tangram[i],context); } function draw(piece,cxt){ cxt.beginPath(); cxt.moveTo(piece.p[0].x,piece.p[0].y); for(var i=1;i<piece.p.length,i++); cxt.lineTo(piece.p[i].x,piece.p[i].y); cxt.closePath(); cxt.fillStyle=piece.color; cxt.fill(); cxt.strokeStyle="black" cxt.lineWidth=3; cxt.stroke(); } } </script> </body> </html>
8:boder---border
12: var tangram={}---var tangram=[
20:];
19:","不要
34:for(var i=1;i<piece.p.length,i++);--for(var i=1;i<piece.p.length;i++)
41: ;
基础不行
