MVC jQuery刪除操作不起作用

Question

我一直在爲這一段時間打破了我的頭。我有下面的表單，工作正常。

@using (Html.BeginForm("Edit", "PCLLine", FormMethod.Post)) 
{ 
    @Html.AntiForgeryToken() 
    @Html.ValidationSummary(true) 

    @Html.HiddenFor(model => model.ID) 
    @Html.HiddenFor(model => model.Field) 
    <div class="small"> 
    @Html.TextBoxFor(model => model.Number, new { onchange = "setEditWBSElementNumber(this," + Model.ID + ")" }) 
    @Html.ValidationMessageFor(model => model.Number) 
    </div> 

    <div class="large"> 
    @Html.EditorFor(model => model.Description) 
    @Html.ValidationMessageFor(model => model.Description) 
    </div> 

    <div> 
    @Html.EditorFor(model => model.NumberTwo) 
    @Html.ValidationMessageFor(model => model.NumberTwo) 
    </div> 

    <div> 
    @Html.TextBoxFor(model => model.ConcatNumber, new { @id = Model.ID.ToString() + "_WBSElementNumber" }) 
    @Html.ValidationMessageFor(model => model.ConcatNumber) 
    </div> 

    <div class="large"> 
    @Html.EditorFor(model => model.Remarks) 
    @Html.ValidationMessageFor(model => model.Remarks) 
    </div> 
    <div> 
    <input type="submit" class="accept" value="Opslaan" /> 
    </div> 
    <div> 
    <input class="folderButton" value="Opties" onclick="pclSubLineDialog()" /> 
    </div> 
    <div> 
    <input class="delete" value="Verwijderen" onclick="deleteItem(); return false;" /> 
    </div> 
} 

這裏的問題在於刪除。它調用該函數，但不能正確執行。它不打我的控制器動作，但與其他控制器動作嘗試它，它的工作：

function deleteItem() { 
    $.ajax({ 
     url: "PCLLine/Delete", 
     type: "POST", 
     data: { id: "@Model.ID" }, 
     dataType: "json", 
     success: function (data) { 
     alert(''); 
     } 
    }); 
    } 

而且控制器：

[AcceptVerbs(HttpVerbs.Post)] 
public ActionResult Delete(int pclLineId) 
{ 
    try 
    { 
    // TODO: Add delete logic here 
    _pclLineBLL.DeletePCLLine(pclLineId); 
    return Json(new { success = true }); 
    } 
    catch 
    { 
    return Json(new { success = false }); 
    } 
} 

Answer 1

參數事項的名稱。你應該根據行動宣言重命名您的請求參數：

data: { pclLineId: "@Model.ID" }, 

Answer 2

在你的控制器類，你命名的參數pclLineId而不是id。

您可以：

1. 重命名參數id
2. 改變你的jQuery函數傳遞的pclLineId代替id

Answer 3

//更改功能

function deleteItem() { 
    $.ajax({ 
     url: "PCLLine/Delete", 
     type: "POST", 
     data: { pclLineId: "@Model.ID" }, 
     dataType: "json", 
     success: function (data) { 
     alert(''); 
     } 
    }); 
    }
