我有一個ASP.NET MVC 4網頁,供我使用下面的HTML代碼來生成終端用戶的一種形式:隱藏字段沒有發送到服務?
@using (Html.BeginForm("JEdit", "Post", FormMethod.Post, new { id = "frmEditPost" }))
{
<div id="postListEditor" class="regularContainer" style="position:relative;">
@Html.ValidationSummary(false)
@Html.HiddenFor(c=> c.Id, false)
<div class="floatLeft">
@Html.LabelFor(c => c.Title, true)
@Html.TextBoxFor(c => c.Title, new { @class = "tb1", @Style = "width:400px;" })
@Html.ValidationMessageFor(model => model.Title)
</div>
<br style="clear:both;" />
<div class="floatLeft">
@Html.LabelFor(c => c.Text, true)
@Html.TextAreaFor(c => c.Text, new { @class = "tb1", @Style = "width:400px; height:200px" })
@Html.ValidationMessageFor(model => model.Text)
</div>
<div style="clear:both;"></div>
@Html.Raw(@Html.SubmitButton("Posta", "btPost", "", "", "ValidateFormAndAjaxSubmit('frmEditPost', this);"))
</div>
}
當單擊提交按鈕下面的JavaScript會拼命地跑:
function ValidateFormAndAjaxSubmit(formId, callingElement) {
if (IsNotDblClick(callingElement.id)) {
var _form = $("#" + formId);
var validator = _form.validate();
var anyError = false;
anyError = !_form.valid();
if (anyError) {
window.latestClick = '';
return false; // exit if any error found
}
$.post(_form.attr("action"), _form.serialize(), function (data) {
if (data.success && data.redirectUrl.length > 0) {
window.location.href = data.redirectUrl;
}
else {
var isValid = validateResponse(_form, data);
window.latestClick = '';
}
})
}
}
問題是hiddenFor不會退回,但所有其他成員都是?我可以在生成的HTML中看到hitten字段被設置爲像這樣:
<input data-val="true" data-val-number="The field Int32 must be a number." data-val-required="The Int32 field is required." id="Id" name="Id" type="hidden" value="21">
那麼爲什麼這個hittenField沒有發回服務?

這是視圖模型的樣子:
public class EditPostViewModel
{
public int Id = -1;
public EditPostViewModel() { }
public EditPostViewModel(string title, string text, string url)
{
Title = title;
Text = text;
Url = url;
}
[Display(Name = "Titel"/*Description = "..."*/)]
[StringLength(100, MinimumLength = 3, ErrorMessage = "...")]
[Required(ErrorMessage="...")]
public string Title { get; set; }
[Display(Name = "Text")]
[StringLength(2500, MinimumLength = 3, ErrorMessage = "...")]
public string Text { get; set; }
[StringLength(100, MinimumLength = 3, ErrorMessage = "...")]
[Display(Name = "Länk")]
[RegularExpression(@"^(http(s)?://([\w-]+.)+[\w-]+(/[\w- ./?%&=])?)?$", ErrorMessage="...")]
public string Url { get; set; }
[Display(Name = "Tags")]
[TagAttribute(ErrorMessage="...a")]
public string Tags { get; set; }
public List<int> TagIdList { get; set; }
public string CustomError { get; set; }
}
使用Fiddler來驗證它確實沒有被髮送。 – usr 2013-03-23 17:18:03
爲什麼你傳遞'false'作爲第二個參數?如果有什麼應該是HTML屬性的匿名對象。如果你不需要額外的屬性,不要傳遞第二個參數。 – rossipedia 2013-03-23 17:20:25
@Bryan,這只是一個測試,如果我刪除它,仍然不會有任何ID發回服務。 – Banshee 2013-03-23 17:27:31
