Question

我添加了电子邮件地址和contactno验证，但是都无法正常工作

我输入此电子邮件地址，然后成功插入数据库：

asda

我输入此联系人编号，然后成功插入数据库中

它给出警告无效，但问题是当我按下按钮然后成功插入数据库时

.cshtml

    ViewBag.Title = "Career";

弹出警报后，按按钮，然后将数据（asd电子邮件地址）成功存储在数据库中

我正在尝试什么：

此版本的代码可以正常工作：

$(document).ready(function() {
  $('#frmsubmit').submit(function() {

    var emailid = document.getElementById("useremailid").value;
    var regx = /^([A-Za-z0-9_\-\.])+\@@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;

    if (emailid) {
      if (regx.test(emailid))
        alert("valid");
      else
        alert("invalid");
      return false;
    }

    var contactno = document.getElementById("usercontactno").value;
    var regx = /\d{10}/;

    if (contactno) {

      if (regx.test(contactno))
        alert("valid");
      else
        alert("invalid");
      return false;

    }
  })
});

您正在验证正则表达式中的错误变量，并且（在问题的原始版本中）在实际提交表单时未运行验证。
