如何使用JavaScript擴展formdata並將其發佈到控制器

如何以某種方式在JavaScript中使用變量擴展formdata，以便在控制器POST操作中可用。如何使用JavaScript擴展formdata並將其發佈到控制器

所以我想要做的是，添加一個變量更新（這是一個布爾），並將這與我的formdata發送到控制器。

這裏是我的.js的代碼文件&控制器代碼

bootbox.confirm("Are you sure you want to override this Quotation?", function (result) { 
     if (result === null) { 
      //do nothing 
     } else if (result) { 
      if (!$form[0].checkValidity()) { 
       return false; 
      } 

      var btn = $('#saveQuotationForm'); 
      btn.attr('onclick', ''); 
      btn.attr('class', 'glyphicon glyphicon-floppy-save'); 
      btn.text('Saving...'); 

      var formurl = $form.attr('action'); 
      var formdata = $form.serialize(); 

      console.log(formurl + " =formurl"); 
      console.log(formdata + " =formdata"); 

      //tricky part, i want to do something like this: 
      //var update = new boolean(false); 
      //formdata.append(update, true); --> but this is obviously not the way to go :), anyone got idea's?** 

      $.post(formurl, formdata, function (data) { 
       if (data && data.State === 'success') { 
        btn.attr('class', 'glyphicon glyphicon-floppy-saved'); 
        btn.text('Saved'); 
        $('#placeholderAlert').append('<div class="alert alert-success" role="alert"><strong>Saved</strong> ' + data.Message + '</div>'); 
       } else { 
        btn.attr('class', 'glyphicon glyphicon-floppy-remove'); 
        btn.text('Saving failed'); 
       } 
      }); 
     } 
    }); 




    [HttpPost] 
    [ValidateAntiForgeryToken] 
    public JsonNetResult Products_Quotation_Save(vmProducts_Quotation_Save quotation) 
    { 
     quotation.DateCreated = DateTime.Now; 
     QuotationCache.Instance.SaveQuotation(GetClientCode(HttpContext), GetUserName(HttpContext), quotation, MuseContext); 
     return JsonNet(new { State = "success", Message = "Quotation '" + quotation.Name + "' has been saved with reference " + quotation.ShortCode + ". <a href=" + Url.Action(RouteItemAction.ResaPlus_Quotations) + " class=\"alert-link\">Go to overview</a>" }); 
    }

編輯： 這的確是一個問題重複，道歉說。我通過這裏提供的答案之一來修復它：jquery form.serialize and other parameters

所以我創建了一個變量並添加了$ .param，然後在我的控制器中我可以訪問該參數。

var update = { 'update': true }; 
var formurl = $form.attr('action'); 
var formdata = $form.serialize() + '&' + $.param(update); 

$.post(formurl, formdata, function (data) { 

}); 

[HttpPost] 
[ValidateAntiForgeryToken] 
public JsonNetResult Products_Quotation_Save(vmProducts_Quotation_Save quotation, bool update) 
{ 
}

嘗試回答這些問題的一個http://stackoverflow.com/questions/10398783/jquery-form-serialize-and-other-parameters – JamieD77

您可以使用serializeArray()創建一個可更新的對象。 http://api.jquery.com/serializeArray/

var formdata = $form.serializeArray(); 
formdata.push({name: 'update', value: true}); 

$.post(formurl, formdata, function (data)
