我在我的 asp.net mvc 项目中使用 jquery 验证。它与 textbox 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>
}

渲染的 html 标记如下所示:

其他验证运行良好。仅文件上传不起作用。你有什么想法吗？

最佳答案

问题在于您的规则针对元素 id 而不是 name。 

fileInput: {
    required: true
}

您的规则正在查找 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="" />

要修复此问题，只需更改规则，使其针对 name 属性...

File: {
    required: true
}

关于javascript - Jquery.Validate 不适用于文件上传，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18109266/
