javascript - 使用 jquery 验证忽略字段文件

Question

这是我的表单和验证 jQuery，但在 UI 中，这在文件上传(多个)中显示了 mensagem“输入不超过 3 个字符”。我认为问题出在文件字段中的属性 maxlength="3" 。

如何删除该字段的验证？

        <table cellpadding="0" cellspacing="0" class="main_table">
                <tr>
                    <td class="label">@Resources.Registo.nome</td>
                    <td>@Html.TextBox("FullName", (Model != null ? Model.FullName : string.Empty), new { @class = "width250" })
                        @Html.ValidationMessageFor(model => model.FullName)</td>
                </tr>
                <tr>
                    <td class="label">@Resources.Registo.email</td>
                    <td>@Html.TextBox("Email", (Model != null ? Model.Email : string.Empty), new { @class = "width250" })
                        @Html.ValidationMessageFor(model => model.Email)</td>
                </tr>
                <tr>
                    <td class="label">@Resources.Registo.exemploFotos</td>
                    <td><input type="file" name="fileUpload" class="multi" accept="jpeg|jpg" maxlength="3" /></td>
                </tr>

                <tr><td colspan="2"><a class="button" onclick="$('#FormToValidate').valid() == true ? get_form(this).submit() : false" id="validateAndSubmitBtn" ><span>@Resources.Global.btnSubmit</span></a></td></tr>
         </table>



$().ready(function () {
        // validate signup form on keyup and submit
        $("#FormToValidate").validate({

            rules: {

                FullName: {
                    required: true
                },
                Email: {
                    required: true,
                    email: true
                }
            },
            messages: {
                FullName: {
                    required: "@Resources.Registo.requiredFullName"
                },
                Email: {
                    required: "@Resources.Registo.requiredEmail",
                    email: "@Resources.Registo.emailValid"
                }
            }
        });

    });

试试忽略参数:

$("#FormToValidate").validate({
    rules: {
        FullName: {
            required: true
        },
        Email: {
            required: true,
            email: true
        }
    },
    messages: {
        FullName: {
            required: "@Resources.Registo.requiredFullName"
        },
        Email: {
            required: "@Resources.Registo.requiredEmail",
            email: "@Resources.Registo.emailValid"
        }
    },
    ignore: "input[type='file']"
});

如果您愿意，您可以为参数使用任何有效的 jQuery 选择器。
