需要验证姓名、体重和身高条目的输入

function validateInput(name, weight, height) {
    let errors = [];

    // 验证姓名
    if (!name || typeof name !== 'string' || name.trim() === '') {
        errors.push('姓名不能为空');
    }

    // 验证体重
    if (isNaN(weight) || weight <= 0 || weight > 500) {
        errors.push('体重必须是大于0且小于等于500的数值');
    }

    // 验证身高
    if (isNaN(height) || height <= 0 || height > 300) {
        errors.push('身高必须是大于0且小于等于300的数值');
    }

    return errors;
}

// 使用示例
let name = "张三";
let weight = 70;
let height = 175;

let validationErrors = validateInput(name, weight, height);
if (validationErrors.length > 0) {
    console.log('验证失败:', validationErrors);
} else {
    console.log('验证成功');
}
