ASP.NET MVC 搜索+保存搜索结果.2个按钮共用一个表单

Posted 2020-10-02

想要实现的效果,1.搜索功能 2.搜索结果保存到text功能

前台代码

一个表单2个按钮,通过JS代码来修改form的action,来实现调用不同的后台代码

            <form name="form1"  action="~/Card/List" method="get" >
                <span class="label label-success">卡号:</span>
                <input class="form-inline" type="text" name="CardNum" placeholder="请输入要查询的卡号" value="@Request.QueryString["CardNum"]" style="width:260px" />
                <span class="label label-success">面值:</span>
                <input type="text" name="Price" placeholder="" value="@Request.QueryString["Price"]" style="width:100px" />
                <span class="label label-success">状态:</span>
                <select name="Status">
                    <option value="2" @(Request.QueryString["Status"] == "2" ? "selected=‘selected‘" : "")> 全部 </option>
                    <option value="-1" @(Request.QueryString["Status"] == "-1" ? "selected=‘selected‘" : "")> 冻结 </option>
                    <option value="0" @(Request.QueryString["Status"] == "0" ? "selected=‘selected‘" : "")> 已用 </option>
                    <option value="1" @(Request.QueryString["Status"] == "1" ? "selected=‘selected‘" : "")> 未用 </option>
                </select>
                <span class="label label-success">创建日期:</span> <input type="date" class="inline laydate-icon" name="CreateDateTime" value="@Request.QueryString["CreateDateTime"]" />
                <button type="submit" class="btn btn-success" onclick="mysearch()">查询</button>
                <button id="SaveText" class="btn btn-success" onclick="myexport()">导出查询结果</button>
            </form>

JS代码

        function mysearch() {
            document.form1.action = "/Card/List";
        }
        function myexport() {
            document.form1.action = "/Card/Export";
        }

后台代码

后台用到了mvcpager分页,用的htmlget方式

        [CheckLogin]
        [HttpGet]
        public ActionResult List(string cardnum, decimal? Price, int? Status, DateTime? CreateDateTime, int id = 1)
        {
            return list(cardnum, Price, Status, CreateDateTime, id);
        }
        [CheckLogin]
        [HttpGet]
        public ActionResult Export(string cardnum, decimal? Price, int? Status, DateTime? CreateDateTime, int id = 1)
        {
            CardService cardS = new CardService();
            var model = cardS.Search2(cardnum, Price, Status, CreateDateTime);
            var items= list(cardnum, Price, Status, CreateDateTime, id);
            string str = string.Empty;
            foreach (var item in model)
            {
                str = str + item.CardNum+"----"+item.Price+"----"+item.CreateDateTime+"----"+item.Status + "\r\n";
            }
            byte[] data = Encoding.UTF8.GetBytes(str);
            return File(data, "text/plain", "卡密.txt");
        }
        private ActionResult list(string cardnum, decimal? Price, int? Status, DateTime? CreateDateTime,int id = 1)
        {
            CardService cardS = new CardService();
            var model = cardS.Search2(cardnum, Price, Status, CreateDateTime);
            PagedList<CardDTO> InfoPager = model.ToPagedList(id, 10);
            InfoPager.TotalItemCount = model.Count();
            InfoPager.CurrentPageIndex = id;
            CardSearchDTO model2 = new CardSearchDTO();
            model2.Cards = InfoPager;
            if (Request.IsAjaxRequest())
                    return PartialView("_AjaxSearchGet", model2);
                return View("List",model2);
            
        }
