刚刚编辑了一下,希望它有所帮助
<html>
<head>
<script type="text/javascript" language="javascript">
// Box width
var bw = 400;
// Box height
var bh = 400;
// Padding
var p = 10;
var canvas = document.getElementById("canvas");
var context = canvas.getContext("2d");
function drawBoard(){
for (var x = 0; x <= bw; x += 40) {
context.moveto(0.5 + x + p,p);
context.lineto(0.5 + x + p,bh + p);
}
for (var x = 0; x <= bh; x += 40) {
context.moveto(p,0.5 + x + p);
context.lineto(bw + p,0.5 + x + p);
}
context.strokeStyle = "black";
context.stroke();
}
drawBoard();
</script>
</head>

<canvas id="canvas" width="420px" height="420px" style="background: #fff; margin:20px"></canvas>
