我有我的数组,我想基于数组中每个对象内的whats显示数组.我在这里有循环,但我似乎可以开始ctx.fillRect工作.
var c = document.getElementById("can");
var ctx = c.getContext("2d");
var blocks = [];
var rows = [0, 1, 2, 3];
function Block(h, w, x, y, c) {
this.h = h;
this.w = w;
this.x = x;
this.y = y;
this.c = c;
}
ctx.fillRect(900, 400, 10, 10)
for (var i = 0, len = rows.length; i < len; i++) {
for (var j = 0; j < 10; j++)
blocks.push(new Block(10, 20, j * 30, i * 30, …
