如何将字符串转换为7位的二进制？(JavaScript)

function convertToBinary(str) {
  let binaryStr = '';
  for (let i = 0; i < str.length; i++) {
    const charCode = str.charCodeAt(i); // 获取字符的ASCII码
    const binary = charCode.toString(2).padStart(7, '0'); // 将ASCII码转换为7位二进制
    binaryStr += binary;
  }
  return binaryStr;
}

// 示例用法
const inputStr = 'Hello';
const binary = convertToBinary(inputStr);
console.log(binary); // 输出: 0100100001100101011011000110110001101111
