JQuery插件，輕量級表單模型驗證，供大家參考，具體內(nèi)容如下

附上源碼和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 + "不能為空")    };  });  return model;})(window.validataForm || {});

調(diào)用處

<form id="ValidataForm">  <input data-required="true" data-name="名稱" data-type="required" value="">  <input data-required="true" data-name="昵稱" 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這個對象是抄一個博主的
代碼附上，內(nèi)置鏈接
