首先，通过创建一个视图模型来代表您要编辑的内容。我假设cashAmount是一个货币值，因此应该是一个十进制（根据需要添加其他验证和显示属性）
public class CashRecipientVM
{
public int? ID { get; set; }
public decimal Amount { get; set; }
[required(ErrorMessage = "Please enter the name of the recipient")]
public string Recipient { get; set; }
}
然后创建局部视图（例如） _Recipient.cshtml
@model CashRecipientVM
<div class="recipient">
@using (Html.BeginCollectionItem("recipients"))
{
@Html.HiddenFor(m => m.ID, new { @class="id" })
@Html.LabelFor(m => m.Recipient)
@Html.Text@R_716_2419@For(m => m.Recipient)
@Html.ValidationMesssageFor(m => m.Recipient)
@Html.LabelFor(m => m.Amount)
@Html.Text@R_716_2419@For(m => m.Amount)
@Html.ValidationMesssageFor(m => m.Amount)
<button type="button" class="delete">Delete</button>
}
</div>
以及返回该部分的方法
public PartialViewResult Recipient()
{
return PartialView("_Recipient", new CashRecipientVM());
}
然后您的主要GET方法将是
public ActionResult Create()
{
List<CashRecipientVM> model = new List<CashRecipientVM>();
.... // add any existing objects that your editing
return View(model);
}
它的看法将是
@model IEnumerable<CashRecipientVM>
@using (Html.BeginForm())
{
<div id="recipients">
foreach(var recipient in Model)
{
@Html.Partial("_Recipient", recipient)
}
</div>
<button id="add" type="button">Add</button>
<input type="submit" value="Save" />
}
并将包含用于添加新HTML的脚本 CashRecipientVM
var url = '@Url.Action("Recipient")';
var form = $('form');
var recipients = $('#recipients');
$('#add').click(function() {
$.get(url, function(response) {
recipients.append(response);
// Reparse the validator for client side validation
form.data('validator', null);
$.validator.unobtrusive.parse(form);
});
});
和删除项目的脚本
$('.delete').click(function() {
var container = $(this).closest('.recipient');
var id = container.find('.id').val();
if (id) {
// make ajax post to delete item
$.post(yourDeleteUrl, { id: id }, function(result) {
container.remove();
}.fail(function (result) {
// Oops, something went wrong (display error message?)
}
} else {
// It never existed, so just remove the container
container.remove();
}
});
表格会寄回给
public ActionResult Create(IEnumerable<CashRecipientVM> recipients)
