我需要检查“成功”是真还是假。我从行动中得到以下json回复:

  

{ “成功”:真}

如果是真或假,我怎么检查它。我试过这个,但它不起作用。它回来未定义

    $.post("/Admin/NewsCategory/Delete/", { id: id }, function (data) {
        alert(data.success);
        if (data.success) {
            $(this).parents('.inputBtn').remove();
        } else {
            var obj = $(this).parents('.row');
            serverError(obj, data.message);
        }
    });

您的控制器操作应如下所示:

[HttpPost]
public ActionResult Delete(int? id)
{
    // TODO: delete the corresponding entity.
    return Json(new { success = true });
}

就我个人而言,我会使用HTTP DELETE动词,它似乎更适合删除服务器上的资源并且更加RESTful:

[HttpDelete]
public ActionResult Delete(int? id)
{
    // TODO: delete the corresponding entity.
    return Json(new { success = true, message = "" });
}

然后:

$.ajax({
    url: '@Url.Action("Delete", "NewsCategory", new { area = "Admin" })', 
    type: 'DELETE',
    data: { id: id }, 
    success: function (result) {
        if (result.success) {
            // WARNING: remember that you are in an AJAX success handler here,
            // so $(this) is probably not pointing to what you think it does 
            // In fact it points to the XHR object which is not a DOM element 
            // and probably doesn't have any parents so you might want to adapt 
            // your $(this) usage here
            $(this).parents('.inputBtn').remove();
        } else {
            var obj = $(this).parents('.row');
            serverError(obj, result.message);
        }
    }
});
