我正在布局一个比较两个密码字符串的视图.我的一个模型中的两个属性非常简单:

    [Required]
    [RegularExpression(@"(\S)+", ErrorMessage = "White space is not allowed")]
    [StringLength(20, MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "New Password")]
    public string NewPassword { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [RegularExpression(@"(\S)+", ErrorMessage = "White space is not allowed")]
    [StringLength(20, MinimumLength = 6)]
    [Display(Name = "Confirm Password")]
    [Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

这是我的观看代码:

<table class="fieldset center" width="400">
    <tbody>
        <tr>
            <th width="150">
                @Html.LabelFor(m => m.NewPassword)
            </th>
            <td>
                @Html.PasswordFor(m => m.NewPassword, …

在使用ajax提交表单之前,我需要检查数据库中是否已存在数据.最常见的情况是检查用户名和电子邮件的可用性.

它不工作,但我测试了ajax功能,而没有使用from控件,它工作正常.该项目是在MVC 3 VB中创建的.

使用Javascript:

$('#addSalesPeople').click(function () {
   $.post("ajax_functions/checkDuplicate.cshtml",
   {
      extension: document.getElementById('Extension').value,
      initials: document.getElementById('Initials').value
   },
      function (data, status) {
      alert("Data: " + data + "\nStatus: " + status);
   });
});

HTML:

@Using Html.BeginForm("Create", "SalesPeople", FormMethod.Post)
@Html.ValidationSummary(True)
@<fieldset>  
    ............................
    ..............................  

    @Html.TextBoxFor(Function(model) model.Extension, New With {.onkeyup = "javascript: charCounter(this,4);", .onblur = "javascript: zeroPad(this, 4)"})

    @Html.TextBoxFor(Function(model) model.Initials)

    <input id="addSalesPeople" class="btn span2" type="submit" value="Add" />

</fieldset>

我在我的模型中使用远程属性来检查重复的页面标题如下

public class Page
{
  [Remote("CheckDuplicate", "Page", ErrorMessage = "Title already taken")]
  public string Title { get; set; }
}

在控制器中,我将根据" 检查 "结果返回JsonResult数据,如下所示:

public JsonResult CheckDuplicate(string Title)
{
   var result = db.Pages.Where(a => a.Title == Title).Count() == 0;
   return Json(result, JsonRequestBehavior.AllowGet);
}

这在Create动作中工作正常,但问题是,它限制了我编辑现有页面,因为它正在检查相同的查询.

如何解决这个问题呢？请建议我
