我在我的asp.net mvc项目中使用jquery验证。它与文本框配合得很好。但它不适用于文件上传。我的代码如下所示：
@model ffyazilim.Management.Model.Credential.CreateModel
@{
ViewBag.Title = "Create";
Layout = "~/Areas/Management/Views/_ManagementLayout.cshtml";
}
@section Scripts
{
<script type="text/javascript">
$(function () {
$('#form').validate({
rules: {
Title: {
required: true,
maxlength: 45,
minlength: 5
},
Description: {
required: true,
maxlength: 250,
minlength: 5
},
Order: {
required: true,
maxlength: 10,
minlength: 1
},
fileInput: {
required: true
}
},
messages: {
fileInput: "Lütfen dosya seçiniz",
}
});
});
</script>
<script>
$(document).ready(function () {
$('#form').ajaxForm({
success: function (response, textStatus, xhr, form) {
$("#alert").addClass('alert alert-success');
$("#alert").html('Kayıt başarılı');
$("#alert").css("display", "block");
},
error: function (xhr, textStatus, errorThrown) {
$("#alert").addClass('alert alert-danger');
$("#alert").html('Kayıt başarısız');
$("#alert").css("display", "block");
},
});
});
</script>
}
@Html.MvcSiteMap().SiteMapPath("BootstrapSiteMapPathHelperModel")
@using (Html.BeginForm(Html.BeginForm("Create", "Credential", FormMethod.Post, new { enctype = "multipart/form-data" ,id="form"})))
{
<table>
<tr>
<div id="alert" style="margin-top: 20px; display:none;"></div>
</tr>
<tr>
<td>Başlık:</td>
<td>@Html.TextBoxFor(m => m.Title)</td>
</tr>
<tr>
<td>Açıklama:</td>
<td>@Html.TextBoxFor(m => m.Description)</td>
</tr>
<tr>
<td>Sıra:</td>
<td>@Html.TextBoxFor(m => m.Order)</td>
</tr>
<tr>
<td>Resim:</td>
<td>@Html.TextBoxFor(m => m.File, new { type = "file" ,id="fileInput"})</td>
</tr>
<tr>
<td></td>
<td>
<input type="submit" class="btn" value="Kaydet" /></td>
</tr>
</table>
}
呈现的html标记如下所示：

其他验证效果很好。只有文件上传不起作用。你知道吗？
答案 0 :(得分：3)
问题是您的规则定位的是元素id，而不是name。
fileInput: {
required: true
}
您的规则正在寻找name属性为fileInput的元素。但是，文件输入元素包含name="File"。
<input id="fileInput" name="File" type="file" value="" />
要修复它，只需更改规则，使其定位name属性...
File: {
required: true
}
