替换 Foreach -> For

Question

我的程序使用 forEach 显示图像。我想用 for

替换它

  images.forEach((img, ind) =>  {
    const oImage = new Image();
        oImage.onload = () => 
        {
          ctx.drawImage(oImage, ind * 100, 0, 100, 100);
        };
    oImage.src = img.textContent;
  }
  );
}

Answer 1

我不明白你为什么要去掉 forEach，但你有答案而且很简单：

for (let i = 0; i < images.length; i++) {
  const oImage = new Image();
  oImage.onload = () => {
    ctx.drawImage(oImage, i * 100, 0, 100, 100);
  };

  oImage.src = images[i].textContent;
}
