js16进制颜色值转rgba

要将JS中的16进制颜色值转换为RGBA格式，可以使用以下代码：

function hexToRgba(hex) {
  const rgba = \[\];
  hex = hex.replace('#', '').padEnd(8, 'F');
  for (let i = 0; i < hex.length; i += 2) {
    rgba.push(parseInt(hex.slice(i, i + 2), 16));
  }
  return rgba;
}

这个函数将接受一个16进制颜色值作为参数，并返回一个包含RGBA值的数组。例如，如果你调用`hexToRgba('#FF0000')`，它将返回`\[255, 0, 0, 255\]`，表示红色的RGBA值。\[3\]
