JQuery和Ajax.BeginForm()两次发布相同的数据

Question

好吧,我是一个网络新手,但我必须承认我现在已经完全迷上了.这是我的问题:

我有一个带有MVCContrib网格的页面和一个"添加帐户"链接,它会打开一个包含在JQuery对话框中的Ajax表单.当我第一次完成工作流程时,一切都很好.我可以通过JQuery/Ajax添加一个新项目并刷新网格(所以我认为).但是,当我尝试第二次添加表单时,始终会提交第一个表单中的数据.我一直在看这个问题的时间太长了,必须承认我完全陷入困境.顺便说一句 - 我确定我这样做完全错了所以请随意提出更好的建议.

这是表格:

@using (Ajax.BeginForm("SaveCheckAccount", "UserManagement", null, new AjaxOptions { OnSuccess = "onAccountAdded", OnFailure = "onAccountAddedFailed"}, new { id = "accountDetails" }))
{
    @Html.ValidationSummary(true)
    @Html.HiddenFor(model => model.Id)
    @Html.HiddenFor(model => model.version)
    @Html.HiddenFor(model => model.User_Id)
    @Html.HiddenFor(model => model.IsDefault)        
    <table>
        <tr>
            <td>
                Account Number
            </td>
            <td>
                @Html.TextBoxFor(model => model.AccountNumber)
                @Html.ValidationMessageFor(model => model.AccountNumber, "*")
            </td>
        </tr>
        <tr>
            <td>
                Routing Number
            </td>
            <td>
                @Html.TextBoxFor(model => model.RoutingNumber)
                @Html.ValidationMessageFor(model => model.RoutingNumber, "*")
            </td>
        </tr>
        <tr>
            <td>
                Account Type
            </td>
            <td>
                @Html.DropDownListFor(model => model.AccountType_Id, new SelectList(@accountTypes, "ID", "Name", Model.AccountType_Id))
                @Html.ValidationMessageFor(model => model.CheckAccountType)
                @Html.ValidationMessageFor(model => model.AccountType_Id, "*")
            </td>
        </tr>
        <tr>
            <td>
                Bank Name
            </td>
            <td>
                @Html.TextBoxFor(model => model.BankName)
                @Html.ValidationMessageFor(model => model.BankName, "*")
            </td>
        </tr>
        <tr>
            <td>
                Account Name
            </td>
            <td>
                @Html.TextBoxFor(model => model.AccountName)
                @Html.ValidationMessageFor(model => model.AccountName, "*")
            </td>
        </tr>
    </table>   
}

<script type="text/javascript">
    $.ajaxSetup({ cache: false });
</script>

这个javascript位于bank.js文件中

function BindCommands(createUrl) {

      $("#modalAdd").live("click", function (e) {
          var dialogBox = $("<div>");
          e.preventDefault();
          $(dialogBox).dialog({
              autoOpen: false,
              resizable: false,
              title: 'Create Account',
              modal: true,
              show: { effect: "blind", duration: 50 },
              hide: { effect: "blind", duration: 50 },
              open: function (event, ui) {
                  $.ajax(
                      {
                          type: "Get",                          
                          url: createUrl,
                          success: function (result) {
                              $(dialogBox).html(result);
                          }
                      });
              },

              buttons: {
                  Save: function () {
                      $("#accountDetails").submit();
                      $(this).dialog('close');                      
                  },
                  Cancel: function () {
                      $(this).dialog("close");
                  }
              }
          });
          $(dialogBox).dialog('open');
      });
  }

  function onAccountAdded(data, status, xhr) {      
      $("#accounts-grid").html(data);
  };

  function onAccountAddedFailed(data, status, xhr) {
      alert("Failed");      
  };

通过单击此视图上的添加链接来初始呈现for:

<script type="text/javascript">
    $.ajaxSetup({cache:false});
    $(document).ready(function() {
        var createUrl = '@Url.Action("NewBankAccountDetails", "UserManagement", new {userId=@Model.Id})';
        BindCommands(createUrl);
    });

</script>       
@if (Model != null && Model.Id > 0)
{

    <tr>
        <td class="header" colspan="2">
            User Accounts
        </td>
    </tr>
    <tr>
        <td>
            <a href="#" id="modalAdd">Add Account</a>
        </td>
    </tr>

    Html.RenderPartial("_BankAccountGrid", Model.CheckAccounts);
}

我遇到了同样的问题并且撞到了墙上,直到我注意到以下脚本被包含两次:

<script src="/Scripts/jquery.unobtrusive-ajax.js"></script>

我在我的包中设置了脚本,视图模板也包含它,这导致了ajax形式的双重帖子.

希望它有所帮助,如果不是双倍的赏金:-P
