c# - 使用 AJAX 调用带参数的视图

Question

所以我有一个AJAX函数，它用参数调用控制器中的视图。当我调试一切正常时，我也得到了正确的结果，但页面没有在浏览器中重新加载。我正在使用将AJAX过滤器应用于列表，但现在视图设置正确，但浏览器中没有重新加载/刷新列表。然后当我自己重新加载时，我得到的列表没有过滤器。（这是有道理的）

例如：我有一个包含猫和狗的列表，并且只为狗应用过滤器，在 ajax 调用完成后，我的列表中仍然有猫。我搜索了很长时间来寻找答案，但没有找到一架喷气式飞机。

在成功函数中添加 alocation.reload();也不起作用，因为随后使用其他参数调用视图，然后在AJAX调用中设置。

所以我只想有一个AJAX调用以p_applicationId作为参数调用视图，它们显示通过调用的视图AJAX

AJAX

 $(document).ready(function ()
{
    $("#applicationDropdown").change(function () {
        var releaseId = $("#applicationDropdown").val();
        var filterReport = $("#filterReport");
         $.ajax({
             type: "POST",
             url: '@Url.Action("Index", "ProductionDeployment")',
             data: { p_applicationId: releaseId },
            success: function (data)
            {
                filterReport.html('Success, The Releases have been filtered.');
            },
            error: function (xhr, ajaxOptions, thrownError)
            {
                filterReport.html('Failed to filter the Releases. ' + thrownError);
                //  alert('Failed to filter the Releases.', xhr, thrownError);
            }
        });
    });
});
