我寫了代碼但是顏色總是填充不上是什么原因呢？

var tangram=[

{p:[{x:0,y:0},{x:600,y:0},{x:300,y:300}],color:"#CEFE68"},

{p:[{x:0,y:0},{x:300,y:300},{x:0,y:600}],color:"#69BED0"},

{p:[{x:150,y:450},{x:0,y:600},{x:300,y:600}],color:"#FAF61C"},

{p:[{x:300,y:300},{x:150,y:450},{x:450,y:450}],color:"#F13C64"},

{p:[{x:450,y:150},{x:300,y:300},{x:450,y:450}],color:"#F78ECE"},

{p:[{x:600,y:0},{x:450,y:150},{x:600,y:300}],color:"#A795C3"},

{p:[{x:600,y:300},{x:300,y:600},{x:600,y:600}],color:"#F7C928"}

];

window.οnlοad=function(){

var canvas=document.getElementById('canvas');

canvas.width=600;

canvas.height=600;

var content=canvas.getContext('2d');

for(var i=0;i

draw(tangram[i],content)

}

function draw(tangram,content){

content.beginPath();

content.moveTo(tangram.p[0].x,tangram.p[0].y);

for(var i=1;i

content.lineTo(tangram.p[i].x,tangram.p[i].y);

content.closePath();

content.fillStyle=tangram.color;

content.fill();

content.strokeStyle='black';

content.lineWidth=2;

content.stroke();

}

}

};

總結(jié)
