Question

我遇到问题，因为当我选择Individual运营商类型时，隐藏字段为空。

我希望Business填写的内容与individual相同如果business和<div class="form-group"> <div class="col-md-10"> @Html.DropDownListFor(m => m.CarrierType, ViewBag.CarrierTypeList as List<SelectListItem>, new { @class = "btn btn-primary btn-block dropdown-toggle", id = "CarrierType" }) </div> </div>  <div id="Individual"> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.DriverLicenseNumber, new { @class = "form-control ", placeholder = "Driver's License Number", required = "required", tabindex = 15 }) @Html.ValidationMessageFor(m => m.DriverLicenseNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VehicleRegNumber, new { @class = "form-control ", placeholder = "Vehicle Registration Number", required = "required", tabindex = 16 }) @Html.ValidationMessageFor(m => m.VehicleRegNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VehiclePlateNumber, new { @class = "form-control ", placeholder = "Vehicle Plate Number", required = "required", tabindex = 17 }) @Html.ValidationMessageFor(m => m.VehiclePlateNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VecInsNum, new { @class = "form-control ", placeholder = "Vehicle Isurance Number", required = "required", tabindex = 18 }) @Html.ValidationMessageFor(m => m.VecInsNum, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.DropDownListFor(m => m.FleetType, ViewBag.NCFleetTypeList as List<SelectListItem>, new { @class = "btn btn-primary dropdown-toggle" }) </div> </div> </div>  <div id="Business"> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.DriverLicenseNumber, new { @class = "form-control ", placeholder = "Driver's License Number", required = "required", tabindex = 15 }) @Html.ValidationMessageFor(m => m.DriverLicenseNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VehicleRegNumber, new { @class = "form-control ", placeholder = "Vehicle Registration Number", required = "required", tabindex = 16 }) @Html.ValidationMessageFor(m => m.VehicleRegNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VehiclePlateNumber, new { @class = "form-control ", placeholder = "Vehicle Plate Number", required = "required", tabindex = 17 }) @Html.ValidationMessageFor(m => m.VehiclePlateNumber, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.TextBoxFor(m => m.VecInsNum, new { @class = "form-control ", placeholder = "Vehicle Isurance Number", required = "required", tabindex = 18 }) @Html.ValidationMessageFor(m => m.VecInsNum, null, new { @class = "text-danger" }) </div> </div> <div class="form-group"> <div class="col-md-10"> @Html.DropDownListFor(m => m.FleetType, ViewBag.CFleetTypeList as List<SelectListItem>, new { @class = "btn btn-primary dropdown-toggle" }) </div> </div> </div>之间的m.somthing相同，则获取相同的值。

我的cshtml如下：

function hideOnLoadCarrierType() {
    $('#Individual').hide();
    $('#Business').hide();
}

$(document).ready(function () {
    hideOnLoadCarrierType();
    $('#CarrierType').change(function () {
        var value = $(this).val();
        if (value == '1') {
            $('#Individual').show();
            $('#Business').hide();
            } else if (value == '2') {
                $('#Individual').hide();
                $('#Business').show();
            } else {
                hideOnLoadCarrierType();
            }
        });
    });

以下JS的作品完美无缺：

required

但问题是;当我填写业务信息并尝试注册时（模型中的所有字段均为Individual），由于read_ascii字段未设置而给我错误。

你能救我吗？谢谢！

您可以尝试为表单编写事件处理程序，并在提交表单之前执行您需要的任何逻辑。在下面的代码段中，我在填写表单时填写了Individuals中Business对应的空白字段：

// Assuming the form has a submit button with id = "submit-btn"
$('#submit-btn').on('click', function() {
    var form = $(this).closest('form');
    var businessDiv = form.find('#Business');
    // Assuming this is only required when Business is selected
    if(businessDiv.is(':visible')) {
        var individual = form.find('#Individual input:text');
        var business = businessDiv.find('input:text');
        for(var i = 0; i < individual.length; ++i) {
            // Perform the required logic here. 
            // I'm just forcing all empty fields in individuals to
            // their business counterpart
            if(individual[i].value === "") {
                individual[i].value = business[i].value;
            }
        }
    }
});
