基于单选按钮选择显示/隐藏输入字段

我是js和学习方面的新手。请帮我更正代码。
输入为:
单选按钮-1;单选按钮-2;
输入字段集1;输入字段集2;输入字段提交。
我想要实现的是:
页面加载时,仅显示单选按钮1和单选按钮2。单击单选按钮-1 input-fields-set-1和input field submit(输入字段提交)将显示,但单击单选按钮-2 input-fields-set-2和input field submit(输入字段提交)将显示。
下面给出了完整的代码。在上面运行这些http://jsfiddle.net/ 它工作得很好,但是在一个网站上,点击任何一个单选按钮都不会出现任何东西。我已将代码上传到https://testing2601.000webhostapp.com/ 用于测试目的,但不起作用。
另外请注意,set-1和set-2中的所有输入字段都是必填字段。
完成.js和.html文件中的代码-

function ageCheck() {
    if  (document.getElementById('below').checked) {
        document.getElementById('ifBelow').style.display = 'block';
        document.getElementById('ifAbove').style.display = 'none';
        document.getElementById('ifChecked').style.display = 'block';
    }
    else if (document.getElementById('above').checked) {
        document.getElementById('ifBelow').style.display = 'none';
        document.getElementById('ifAbove').style.display = 'block';
        document.getElementById('ifChecked').style.display = 'block';
    }
    else    {
        document.getElementById('ifAbove').style.display = 'none';
        document.getElementById('ifBelow').style.display = 'none';
        document.getElementById('ifChecked').style.display = 'none';
    }
}

当我看到你的代码在https://testing2601.000webhostapp.com/ ,我看到您的javascript代码(来自main.js)如下所示,如果是这样的话 ageCheck 未连接到全局,因此无法定义供您的html使用,这是它不起作用的根本原因。

(function($) {    

    function ageCheck() {
    if  (document.getElementById('below').checked) {
        document.getElementById('ifBelow').style.display = 'block';
        document.getElementById('ifAbove').style.display = 'none';
        document.getElementById('ifChecked').style.display = 'block';
    }
    else if (document.getElementById('above').checked) {
        document.getElementById('ifBelow').style.display = 'none';
        document.getElementById('ifAbove').style.display = 'block';
        document.getElementById('ifChecked').style.display = 'block';
    }
    else    {
        document.getElementById('ifAbove').style.display = 'none';
        document.getElementById('ifBelow').style.display = 'none';
        document.getElementById('ifChecked').style.display = 'none';
    }
    }
})(jQuery);
