验证ASP时回发..NET MVC表单

本文关键字：NET MVC 表单 ASP 验证 | 更新日期: 2023-09-27 17:51:08

我创建了一个web表单表单使用asp.net mvc脚手架，它不工作客户端验证没有回发。[Required()]是postbacking， [EmailAddress] validator是在客户端验证。我使用visual studio 2013和asp.net mvc 5与ef6。这是我的模型类:

namespace WebApplication4.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
public partial class Tutor
{
    public Tutor()
    {
        this.Examinations = new HashSet<Examination>();
    }

    public decimal TutorID { get; set; }
    [Display(Name = "First Name ")]
    [Required(ErrorMessage = "Please Enter First Name.")]
    [DataType(DataType.Text)]
    public string FirstName { get; set; }
    [Display(Name = "Last Name ")]
    [Required(ErrorMessage = "Please Enter Last Name.")]
    [DataType(DataType.Text)]
    public string LastName { get; set; }
    [Display(Name = "Address Line 1 ")]
    [Required(ErrorMessage = "Please Enter Address Line 1.")]
    [DataType(DataType.Text)]
    public string Address1 { get; set; }
    [Display(Name = "Address Line 2 ")]
    [Required(ErrorMessage = "Please Enter Address Line 2.")]
    [DataType(DataType.Text)]
    public string Address2 { get; set; }
    [Display(Name = "Address Line 3 ")]
    public string Address3 { get; set; }
    [Display(Name = "Telephone 1 ")]
    [Required(ErrorMessage = "Please Enter Telephone No.")]
    [DataType(DataType.Text)]
    public string Tel1 { get; set; }
    [Display(Name = "Telephone 2 ")]
    [DataType(DataType.Text)]
    public string Tel2 { get; set; }
    [Display(Name = "Email Address")]
    [Required(ErrorMessage = "Please Enter E Mail Address.")]
    [EmailAddress(ErrorMessage = "Invalid Email Address")]
    [DataType(DataType.EmailAddress)]
    public string EMail { get; set; }
    [Display(Name = "Password ")]
    [DataType(DataType.Password)]
    public string Password { get; set; }
    public Nullable<bool> IsConfirmed { get; set; }
     public virtual ICollection<Examination> Examinations { get; set; }
    }
}

这是我的控制器Create()方法在控制器:

    // GET: /Default1/Create
    public ActionResult Create()
    {
        return View();
    }
    // POST: /Default1/Create
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include="TutorID,FirstName,LastName,Address1,Address2,Address3,Tel1,Tel2,EMail,Password,IsConfirmed")] Tutor tutor)
    {
        if (ModelState.IsValid)
        {
            db.Tutors.Add(tutor);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        return View(tutor);
    }


  @model WebApplication4.Models.Tutor
  @{
     ViewBag.Title = "Create";
     Layout = "~/Views/Shared/_Layout.cshtml";
   }
   <h2>Create</h2>

   @using (Html.BeginForm()) 
    {
     @Html.AntiForgeryToken()
     <div class="form-horizontal">
      <h4>Tutor</h4>
      <hr />
      @Html.ValidationSummary(true)
      <div class="form-group">

        <div class="col-md-10">
            @Html.EditorFor(model => model.FirstName)

    </div>
    <div class="form-group">

        <div class="col-md-10">

    </div>
    <div class="form-group">

        <div class="col-md-10">

    </div>
    <div class="form-group">

    </div>

            @Html.ValidationMessageFor(model => model.Tel2)

    </div>
</div>
}
<div>
     @Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

我想验证所有的东西在客户端。

验证ASP时回发..NET MVC表单

确保正确加载jquery.validate.js库

BundleConfig.cs 

bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.unobtrusive*",
                        "~/Scripts/jquery.validate*"));

页面末尾

@Scripts.Render("~/bundles/jqueryval")

解决方案是使用jquery.validate.unobtrusive.js。

一旦你加载了表单，使用jquery在文档准备你应该解析表单

//file: your view file
@model Tutor
<script>
$(document).ready(function() {
   $.validator.unobtrusive.parse($("#frm1"));
}
function onSubmit(e) {
  $("#frm1").validate(); // this will validate the form and show the validation messages
  if($("#frm1").valid()) {
     $("#frm1").submit(); // submits the form
  }
  return false;//prevent default submit of form by returning false.
  //also e.preventDefault() can be used.
}
</script>
//for understanding purpose using the plain form tag.
//one can use  @using (Html.BeginForm())
<form id="frm1" onsubmit="onSubmit();">
<!-- your content goes here -->
   <div class="form-group">
        @Html.LabelFor(model => model.FirstName, new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.FirstName)
            @Html.ValidationMessageFor(model => model.FirstName)
        </div>
    </div>
</form>
