JavaScript对象值校验：确保字符串和数组非空

const load = {
  trolleyNo: "",
  trolleyItems: [],
  cartType: ""
};

/**
 * 检查对象的所有值，确保字符串和数组类型字段均非空。
 * 对于其他类型的值（如数字、布尔值、嵌套对象等），只要它们不是 null 或 undefined，则视为有效。
 *
 * @param {Object} obj - 待校验的对象。
 * @returns {boolean} 如果所有字符串和数组值均非空，且其他值非 null/undefined，则返回 true；否则返回 false。

function isValidObjectValues(obj) {
  // 1. 基本输入校验：确保输入是有效的非数组对象
  if (obj === null || typeof obj !== 'object' || Array.isArray(obj)) {
    console.warn("isValidObjectValues: Input must be a non-null, non-array object.");
    return false;
  }

  // 2. 检查对象是否为空对象。如果对象本身没有属性，根据需求，它不应被视为“有效”的。
  if (Object.keys(obj).length === 0) {
    console.warn("isValidObjectValues: Object is empty, no values to validate as non-empty.");
    return false;
  }

  // 3. 遍历所有值并应用校验逻辑
  return Object.values(obj).every(value => {
    if (typeof value === 'string') {
      // 对于字符串类型：必须非空
      return value.length > 0;
    } else if (Array.isArray(value)) {
      // 对于数组类型：必须非空
      return value.length > 0;
    } else if (value === null || value === undefined) {
      // 对于其他类型：不允许为 null 或 undefined
      return false;
    }
    // 对于数字、布尔值、其他对象等，只要它们存在且不是 null/undefined，就视为有效。
    // 如果对这些类型有更严格的非空定义（例如数字0或布尔值false被视为无效），
    // 则需要在此处添加额外的逻辑。
    return true;
