jQuery表单验证

我在尝试用Jquery验证修改errorClass和validClass时遇到了很多麻烦。
我假设我所需要做的就是添加.validate函数并设置参数。
虽然验证确实触发并且显示了验证消息，但是类仍然被更改为标准的“input-validation-error”或“valid”。
在浏览器中没有抛出任何JQuery错误。
我相信这个问题可能与阻止应用jquery.validate设置的不显眼的插件有关。
JQuery 3.7.0版、JQuery验证1.19.5版、JQuery验证非强制性4.0.0版
脚本：

@section Scripts {
  $(document).ready(function (e) {
            $("#myForm").validate({
                errorClass: "is-invalid",
                validClass: "is-valid"
            });
  });
}

您可以尝试以下操作：

<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<script src="~/lib/jquery-validation/dist/jquery.validate.min.js"></script>
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.min.js"></script>
 <script>
$.validator.setDefaults({
    validClass: "is-valid",
    // set error class doesn't work here ,so i have to try with hard code for error class
    //errorClass: "is-invalid",
          
    highlight: function (element, errorClass, validClass) {
        $(element).addClass("is-invalid").removeClass(validClass);
        
    },
    unhighlight: function (element, errorClass, validClass) {
        $(element).addClass(validClass).removeClass("is-invalid");
    },
});

使用.setDefaults中的highlight和unhighlight函数会导致验证在使用提交按钮之前触发。
我自己的解决方案是在验证器和不显眼的设置中设置自定义类。

const validationCustomSettings = {
    validClass: "is-valid",
    errorClass: "is-invalid",
};
       
jQuery.validator.setDefaults(validationCustomSettings);           
jQuery.validator.unobtrusive.options = validationCustomSettings;
