JQuery插件，轻量级表单模型验证，供大家参考，具体内容如下

附上源码和Demo段

var validataForm = (function(model) {
  model.Key = "[data-required='true']";
  model.ElementList = new Array();
  model.FunctionDictionary = new Dictionary();
  model.ToastrCustom = function (msg) {
    alert(msg);
  }

  model.AddElement = function (name) {
    model.ElementList.push(name);
  };

  model.AddFunction = function (name, func) {
    model.FunctionDictionary.add(name, func);
  };

  model.Validata = function (formName) {
    for (var i = 0; i < model.ElementList.length; i++) {
      var thisObj = model.ElementList[i];
      var str = formName + " " + thisObj + model.Key;
      var elements = $(str);

      for (var j = 0; j < elements.length; j++) {
        var element = elements.eq(j);
        var value = element.val();

        var elementType = element.data().type;

        var func = model.FunctionDictionary.find(elementType);
        if (func) {
          var result = func(value, element);

          if (result.status) {
            var errorInfo = result.message;
            model.ToastrCustom(errorInfo);
            return;
          }
        }
      }
    }
  };

  model.ElementList.push("input");
  model.ElementList.push("select");
  model.FunctionDictionary.add("required", function (value, element) {
    var name = element.data().name;

    return {
      status: (value === ""),
      message: (value === "" && name + "不能为空")
    };
  });

  return model;
})(window.validataForm || {});

调用处

<form id="ValidataForm">
  <input data-required="true" data-name="名称" data-type="required" value="">
  <input data-required="true" data-name="昵称" data-type="hello">
  <button id="Send">提交</button>
</form>
<script src="~/js/plugs/jquery-3.3.1.js"></script>
<script src="~/js/Dictionary.js"></script>
<script src="~/js/ValidataForm.js"></script>
<script type="text/javascript">
  $("#Send").click(function () {
    validataForm.Validata("#ValidataForm");
  });
</script>

Dictionary这个对象是抄一个博主的
代码附上，内置链接

/* https://www.cnblogs.com/baiyangyuanzi/p/6689554.html */
/*字典 Dictionary类*/
function Dictionary() {
  this.add = add;
  this.datastore = new Array();
  this.find = find;
  this.remove = remove;
  this.count = count;
  this.clear = clear;
}

function add(key, value) {
  this.datastore[key] = value;
}

function find(key) {
  return this.datastore[key];
}

function remove(key) {
  delete this.datastore[key];
}

function count() {
  /*var ss = Object.keys(this.datastore).length;
  console.log("ssss  "+ss);
  return Object.keys(this.datastore).length;*/
  /**/
  var n = 0;
  for (var key in Object.keys(this.datastore)) {
    ++n;
  }
  return n;
}

function clear() {
  for (var key in this.datastore) {
    delete this.datastore[key];
  }
}
