表的ASP.NET最佳实践 Download


我正在使用一个表进行ASP.NET Core项目开发，该表具有基于它们所在的当前选项卡的筛选器。我最初的想法是使用JSON调用C＃并获取表中合格项目的列表。

我想到的下一个计划可能是获取所有合格项目的列表，然后在for循环中使用过滤器？

    public JsonResult OnGetGetSetups(string condition,int vehID)
    {
        if (vehID == 0)
            return null;

        switch (condition)
        {
            case "Dirt":
                return new JsonResult(_context.Setups.Include(d => d.Driver).Include(sd => sd.SetupDetails).Include(c => c.SetupDetails.Condition).Where(a => a.SetupDetails.Condition.Name == condition && a.VehicleId == vehID).ToList());
            case "Carpet":
                return new JsonResult(_context.Setups.Include(d => d.Driver).Include(sd => sd.SetupDetails).Include(c => c.SetupDetails.Condition).Where(a => a.SetupDetails.Condition.Name == condition && a.VehicleId == vehID).ToList());
            default:
                List<Setup> tmp = _context.Setups.Include(d => d.Driver).Include(sd => sd.SetupDetails).Include(c => c.SetupDetails.Condition).Where(a => a.VehicleId == vehID).ToList();
                return new JsonResult(tmp);
        }
    }

然后我有3个事件监听器，称为“ GetSetups”。这似乎是解决此问题的非常混乱的方法。有更好的方法来解决这个问题吗？

类似的东西：

$(function () {
    $("#allSetups").on("click", function () {
        if (activeTab == "allSetups") {
            return;
        }
        activeTab = "allSetups";

        $("#infoArea").empty();
        var vehId = document.getElementById('vehicleId').value;
        var url2 = '@Url.Page("/setups/search","GetSetups")';
        $.getJSON(url2, { condition: "all", vehID: vehId }, (data) => {
            $.each(data, function (i, item) {
                $("#vehcileId").append(`<option value="${item.vehicleId}">${item.name}</option>`);
            });
        });
    });
});

您可以尝试这种方式：

    public JsonResult OnGetGetSetups(string condition, int vehID)
    {
        if (vehID == 0)
            return null;

        return new JsonResult(_context.Setups.Include(d => d.Driver)
                                             .Include(sd => sd.SetupDetails)
                                             .Include(c => c.SetupDetails.Condition)
                                             .Where(a => a.VehicleId == vehID
                                                        && ((condition != "Dirt" && condition != "Carpet") || a.SetupDetails.Condition.Name == condition))
                                             .ToList());
    }
