我正在努力通过Ajax将数据传递给控制器​​

Question

试图通过Ajax敲击DeleteJobQuote控制器，但没有运气。如果有人有任何想法，请指导我。代码看起来不错，但无法做到。我正在编写此代码以从数据库中删除特定的记录。

控制器

[HttpPost] 
public ActionResult DeleteJobQuote(int jobQuoteid) 
{ 
    using (var db = new KeysEntities()) 
    { 
     var delJob = db.JobQuote.FirstOrDefault(x => x.Id == jobQuoteid); 
     if (delJob != null) 
     { 
      delJob.Status = "Delete"; 
      db.SaveChanges(); 
      return Json(new { success = true, Message = "JobQuote SuccessFully Deleted!" }); 
     } 
     else 
     { 
      return Json(new { success = false, Message = "Delete UnSuccessFul " }); 
     } 
    } 
} 

和JavaScript和敲除此

self.deleteJobQuote = function (jobQuote) { 
    debugger; 
    $.ajax({ 
     url: '/Companies/Manage/DeleteJobQuote', 
     type: 'POST', 
     dataType: 'json', 
     data: ko.toJSON(this), 
     contentType: 'application/json', 
     success: function (result) { 
      if (result.success) { 
       $('#jobQuoteDeleteModal').modal('show'); 
      } 
      else { 
       alert("You can not delete this record !!"); 
      } 
     } 
    }); 
};

更改代码 “数据：ko.toJSON（这）” 到“数据：JSON.stringify（{ jobQuoteid：1}）“。我已将jobQuoteid值硬编码为1.从jobQoute对象获取它。

完整代码：

$.ajax({ 
       url: '/Companies/Manage/DeleteJobQuote', 
       type: 'POST', 
       dataType: 'json', 
       data: JSON.stringify({ jobQuoteid: 1 }), 
       contentType: 'application/json', 
       success: function (result) { 
        if (result.success) { 
         $('#jobQuoteDeleteModal').modal('show'); 
        } 
        else { 
         alert("You can not delete this record !!"); 
        } 
       } 
      });
