我是 jquery 的新手，我想在 asp.net mvc 中验证我的表单。现在验证适用于每个字段，但我想保持禁用提交按钮，直到某些特定字段以正确的方式插入。当我完成插入所有字段时，创建按钮仍然被禁用，我不知道为什么
$(this).hasClass('has-success')
一直返回false
这是我正在使用的代码：
@model StudentsManagment.Models.student
@{
ViewBag.Title = "Create";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Create</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal" id="studentForm">

<hr />
