Javascript将4个整数放入RGBA范围

function createRGBA(red, green, blue, alpha) {
  // 确保每个值都在其有效范围内
  red = Math.max(0, Math.min(255, red));
  green = Math.max(0, Math.min(255, green));
  blue = Math.max(0, Math.min(255, blue));
  alpha = Math.max(0, Math.min(1, alpha));

  // 将整数转换为十六进制字符串
  const redHex = red.toString(16).padStart(2, '0');
  const greenHex = green.toString(16).padStart(2, '0');
  const blueHex = blue.toString(16).padStart(2, '0');

  // 创建RGBA字符串
  const rgbaColor = `rgba(${red}, ${green}, ${blue}, ${alpha})`;

  return rgbaColor;
}

// 示例使用
const rgba = createRGBA(128, 255, 64, 0.5);
console.log(rgba); // 输出: rgba(128, 255, 64, 0.5)
