Question

我正在使用MVC 3开发一个Web应用程序，并希望在用户成功删除项目后向用户返回一条消息。

MyWallController方法如下所示：

[HttpPost]
public ActionResult DeleteAlbum(Guid albumId)
{
    try
    {
        this.albumService.DeleteAlbum(albumId);
        return Json(new { success = true, msg = "Album successfully deleted" }, JsonRequestBehavior.AllowGet);
    }
    catch (FPSException e)
    {
        return Json(new { success = false, msg = e.Message });
    }
    catch (Exception)
    {
        throw new HttpException(500, "Error while deleting album");
    }
}

链接：

<a class="open-DeleteAlbumDialog" href="http://localhost:2941/MyWall/DeleteAlbum?albumId=0f49b1ad-8ec1-4fca-b8e2-28bdbf47824e">Delete</a>

JavaScript：

$(function () {
    $(document).on('click', '.open-DeleteAlbumDialog', function () {
    var answer = confirm('Are you sure you want to delete this album?')
    if (answer) {
        $.post(this.href, function (data) {
            if (data.success) {
                // do something
            } else {
                // do something else
            }
        });
    }
    else return false;
});

然而，post中定义的函数永远不会被调用，而我得到的是“无法找到资源”。但该项目已成功删除。

您的链接仍然有效。您需要preventDefault：

$(function () {
    $(document).on('click', '.open-DeleteAlbumDialog', function (e) {
    e.preventDefault();
    var answer = confirm('Are you sure you want to delete this album?')
    if (answer) {
        $.post(this.href, function (data) {
            if (data.success) {
                // do something
            } else {
                // do something else
            }
        });
    }
});

删除项目后返回JSON结果
