jquery – Mvc json响应检查true / false

前端之家收集整理的这篇文章主要介绍了jquery – Mvc json响应检查true / false前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我需要检查“成功”是真还是假.我从动作中得到以下json响应:

{“success”:true}

我怎么能检查它是真还是假.我试过这个,但它不起作用.它回来了未定义

$.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);
        }
    });

解决方法

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 });
}

就个人而言,我会使用HTTP DELETE动词,这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);
        }
    }
});
