C# MVC 批量修改商品数据
Html: //批量修改折扣
$("#Confirm").click(function () {
// $.ajaxSettings.async = false;//取消异步
var Category= $("#Category1").val();//获取商品类别
var Brand= $("#Brand1").val();//获取品牌
var Season= $("#Season1").val();//获取季节
var plggxszk = $("#plggxszk").val();//获取销售折扣
// $.getJSON("/JH/Commodity/MrketDiscount?Category=" + Category + "&Brand=" + Brand + "&Season=" + Season + "&Discount=" + plggxszk)
$.ajax({
url: "/JH/Commodity/MrketDiscount?Category=" + Category + "&Brand=" + Brand + "&Season=" + Season + "&Discount=" + plggxszk,
type: "get",
success: function (data) {
if (data.State) {
layer.msg(data.Text, { icon: 1, skin: "layui-layer-molv" });
}
}
})
})
UIL:
public ActionResult MrketDiscount(int Category, int Brand, int Season, decimal Discount)
{
//实例化返回的字符
ReturnJson returnJson = new ReturnJson();
var list = (from tbShangPin in myModels.JC_ShangPin
select new Discount
{
ShangPinTypeID = (int)(tbShangPin.ShangPinTypeID),
PinPaiID = (int)(tbShangPin.PinPaiID),
JiJieID = (int)(tbShangPin.JiJieID),
XiaoShozheko = (int)(tbShangPin.XiaoShozheko),
ShangPinID = tbShangPin.ShangPinID
}).ToList();
//判断是否选中商品类型
if (Category > 0)
{
list = list.Where(m => m.ShangPinTypeID == Category).ToList();
}
if (Brand > 0)
{
list = list.Where(m => m.PinPaiID == Brand).ToList();
}
if (Season > 0)
{
list = list.Where(m => m.JiJieID == Season).ToList();
}
if (list.Count > 0)
{
for (var i = 0; i < list.Count; i++)
{
//声明变量 用于查询修改的商品ID
var a = list[i].ShangPinID;
JC_ShangPin ShangPin = (from tbSP in myModels.JC_ShangPin
where tbSP.ShangPinID == a
select tbSP).Single();
ShangPin.XiaoShozheko = Discount;
//list[i].XiaoShozheko = Discount;
myModels.Entry(ShangPin).State = System.Data.Entity.EntityState.Modified;
myModels.SaveChanges();
}
}
returnJson.State = true;
returnJson.Text = "批量更新折扣成功！";
return Json(returnJson, JsonRequestBehavior.AllowGet);
}
效果图：
说明：先查询出需要修改的数据有多少条，再根据查询出了的商品ID，用for循环循环修改数据就可以了。
