您必须包含任何版本的jquery 验证插件

而且您的SCRIPT无效

它的$(document).ready(function() {不是~~$().ready.(function()~~
使用最小长度，最大长度而不是最小长度，~~最大长度~~
验证消息是字符串而不是~~具有空格的变量~~
使用$("#form1").validate({ 不是 ~~$(".selector").validate({~~

尝试这个

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script>
    $.validator.setDefaults({submitHandler: function() { alert("submitted!");}});
    $(document).ready(function() {
       $("#form1").validate({
            rules: {
                40: {required : true,minlength : 2,maxlength : 3 },
                41: {required : true,minlength : 2,maxlength : 3 },
                42: {required : true,minlength : 2,maxlength : 3 },
                43: {required : true,minlength : 2,maxlength : 3 },

您必须包含验证插件，例如 http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js

有关更多详细信息，请查看http://jqueryvalidation.org/

尝试添加

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>

在头部

您的代码中有很多错误。

要清楚地了解如何使用 jquery 验证，请查看此代码

  <script src="//code.jquery.com/jquery-1.9.1.js"></script>
  <script src="//ajax.aspnetcdn.com/ajax/jquery.validate/1.9/jquery.validate.min.js"></script>

  <!-- jQuery Form Validation code -->
  <script>

   $("#register-form").validate({

    // Specify the validation rules
    rules: {

        lastname: "required",
        email: {
            required: true,

        },
        password: {
            required: true,
            minlength: 5
        },
        agree: "required"
    },

    // Specify the validation error messages
    messages: {
        firstname: "Please enter your first name",
