[英]ASP.NET MVC 3 AJAX request returns 404 Not Found error
這是我的代碼(以下發現問題):
視圖
// This function is called by another function when radioButtonGroup.change().
var requestValues = function (form) {
var option = form.find("input:radio:checked").attr("value");
// This seemingly shows the correct url for the action method desired.
alert("Form Action: " + form[0].action + "\nForm Method: " + form[0].method);
if (form.valid()) {
$.ajax({
url: form[0].action,
type: form[0].method,
data: option,
success: function (result) {
alert("Had success.");
$('#createForm').replaceWith(result);
},
error: function (xhr) {
alert("An error occurred: " + xhr.status + " " + xhr.statusText);
}
});
}
return false;
}
...(other code here)...
@using (Html.BeginForm("CreateForm", "MyController", FormMethod.Post,
new { @id = "optionForm" }))
{
<div id="options">
@foreach (MyOption op in Model.GetOptions()) {
<div class="editor-field">
@Html.RadioButton("formOption", op.OptionType, false,
new { @id = op.ID, @title = @op.Description })
<label for="@op.ID">@op.Name</label>
</div>
}
</div>
<input type="submit" value="Select" style="display:none;" />
}
CONTROLLER
[HttpPost]
public PartialViewResult CreateForm(MyOptionType formOption) {
MyViewModel model = new MyViewModel();
model.ApplyOptionValues(formOption);
return PartialView("_CreateForm", model);
}
注冊路線
// Default
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
我的問題是,當我單擊單選按鈕時,將執行AJAX請求,但出現“ 404 Not Found”錯誤(即使jQuery函數中的alert
似乎顯示了適當的URL)。 昨天我整天都在此上度過,我無法弄清楚到底是什么問題。 我在IIS Express上運行ASP.NET MVC 3應用程序,但我沒有使用Areas(無論如何我都知道)。 有人對如何解決此問題有任何建議嗎? 謝謝。
編輯
警報框顯示以下消息:
表單操作:
https://localhost:44300/MyController/CreateForm
形成方式:過帳

這是重新生成錯誤的整個測試視圖和測試控制器:
視圖
<h2>TestAction</h2>
<script type="text/javascript">
$(document).ready(function () {
$("#optionForm input[name='radioOption']").change(function () {
requestValues($(this).closest("form"));
});
var requestValues = function (form) {
var option = form.find("input:radio:checked").attr("value");
alert("Form Action: " + form[0].action + "\nForm Method: " + form[0].method);
if (form.valid()) {
$.ajax({
url: form[0].action,
type: form[0].method,
data: option,
success: function (result) {
alert("AJAX success.");
//$('#createForm').replaceWith(result);
},
error: function (xhr) {
alert("An error occurred: " + xhr.status + " " + xhr.statusText);
}
});
}
return false;
}
});
</script>
@using (Html.BeginForm("CreateForm", "Test", FormMethod.Post, new { @id = "optionForm" })) {
@Html.RadioButton("radioOption", "value1", false, new { @id = "radioButton1" })
<label for="radioButton1">Radio Button 1</label>
@Html.RadioButton("radioOption", "value2", false, new { @id = "radioButton2" })
<label for="radioButton2">Radio Button 2</label>
@Html.RadioButton("radioOption", "value3", false, new { @id = "radioButton3" })
<label for="radioButton3">Radio Button 3</label>
<input type="submit" value="Select" style="display:none;" />
}
<div id="createForm"></div>
CONTROLLER
public class TestController : Controller {
public ActionResult TestAction() {
return View();
}
[HttpPost]
public ActionResult CreateForm(string option) {
return View("TestAction");
}
}
@using (Html.BeginForm("CreateForm", "MyController", FormMethod.Post, new { id = "optionForm" }))
應該:
@using (Html.BeginForm("CreateForm", "My", FormMethod.Post, new { id = "optionForm" }))
請記住,在ASP.NET MVC幫助器中,您不應傳遞Controller
后綴。 這是假定的。
因此正確的網址應為:
https://localhost:44300/My/CreateForm
並不是:
https://localhost:44300/MyController/CreateForm
您顯然擁有MyController
類:
public class MyController: Controller
{
public ActionResult CreateForm(MyOptionType formOption)
{
...
}
}
