jquery - jQuery测验（多选，输入）

Question

为了建立我的网站，我正在尝试进行不同形式的测验。至于现在，我正在使用这个：https ://codepen.io/helloayo/pen/ZBvEag

我的问题/要求是：是否可以进行相同的测验但使用输入文本而不是多项选择选项？

此外，输入和多项选择类型都应该存在的功能，每个错误问题的解释？

出于某种原因，截断的代码会引发错误，但会忽略它，因为代码在 jfiddle、codepen 和我的网站上都可以正常工作。

(function ($) {
  $.fn.emc = function (options) {
    var defaults = {

      settings = $.extend(defaults, options),
