使用ajax mvc3傳遞參數給jquery .net

Question

我正在爲某個站點構建一個後臺，並且在這裏我需要使用ajax從數據庫中刪除註釋，問題是我不能傳遞我想要隱藏的id在Ajax中刪除jQuery。以下是評論的代碼：

<% foreach (var item in Model) { %> 
    <div class="row" id = "row<%= item.CommentID %>"> 
     <div class="editor-label detail">Comment</div> 
     <div class="form-element"><%: Html.DisplayFor(modelItem => item.Text) %></div> 
     <div class="editor-label detail">Date</div> 
     <div class="form-element"><%: Html.DisplayFor(modelItem => item.Date) %></div> 
     <div class="form-element"> 
     <div class="button delete"><%: Ajax.ActionLink("Delete", "Deletecomment", new { id = item.CommentID }, new AjaxOptions { HttpMethod = "POST", OnSuccess = "deleteRow" })%></div> 
     </div> 
    </div> 
<% } %> 

這是控制器代碼：

[AcceptVerbs(HttpVerbs.Post)] 
     public ActionResult Deletecomment(int id) 
     { 
      cr.Delete(cr.getComment(id)); //cr is the conx to the repository 
      cr.Save(); 

      return View("Index"); 
    } 

這是我的jQuery

function deleteRow() { 
    var url_ = this.url.split("/"); 
    $("#row" + url_[url_.length - 1]).remove(); 
} 

什麼，我做的是採取URL和拆分它採取在DB分錄的ID然後將其添加到窗體作爲ID，然後刪除該ID，但我相信有更好的解決方案

假設你正在使用jQuery不顯眼的AJAX腳本，你可以傳遞參數給回調：

<%= Ajax.ActionLink(
    "Delete", 
    "Deletecomment", 
    new { 
     id = item.CommentID 
    }, 
    new AjaxOptions { 
     HttpMethod = "POST", 
     OnSuccess = "deleteRow('#row" + item.CommentID + "')" 
    } 
) %> 

然後：

function deleteRow(row) { 
    $(row).remove(); 
} 

Answer 2

你能不能在ID動態傳遞給回調：

new AjaxOptions { HttpMethod = "POST", OnSuccess = "function(){ return deleteRow('" + item.CommentID + "');" } 

function deleteRow(id) { 
    $("#row" + id).remove(); 
}
