.net layui 批量导出

.net开发,前台使用layui框架,后台使用WCF

废话不多,直接上代码

1>文件引用：

admin.css
layui.css
layui.js
jquery.min.js
layerTool.js

2>前台:

 <script type="text/html" id="toptoolbar">
 　　<button class="layui-btn layui-btn-sm" lay-event="ExportExcel">批量导出</button>
 </script>

----------先来个批量导出的按钮    (ExportExcel)自定义

layui.use(['table', 'form', 'util'], function () {
　　　 var form = layui.form, layer = layui.layer;
      var table = layui.table;
      var field = null;
      var util = layui.util;
　　　　
　　　 table.on('toolbar(ListSupplierTable)', function (obj) {
            switch (obj.event) {
                case 'ExportExcel'://批量导出
                    ShowExportExcelWin();
                    break;
            };
        });
 });

----------（'table', 'form', 'util'）看需求增减

----------(var form = layui.form, layer = layui.layer;    var table = layui.table;    var field = null;    var util = layui.util;)  看需求增减

----------ShowExportExcelWin  //方法名

//打开批量导出弹窗
        var exportOpen;
        function ShowExportExcelWin() {
            var $ = layui.jquery;
            var html = '<div class="layui-form">';
            html += '   <div class="layui-form-item">';
            html += '        <div class="layui-input-inline" style="padding-left:55px;padding-top:20px;">';
            html += '           <input type="radio" name="rdowhere" value="1" title="全部导出" checked><br />';
            html += '           <input type="radio" name="rdowhere" value="2" title="按筛选条件导出" >';
            html += '       </div>';
            html += '   </div>';
            html += '</div>';
            exportOpen = layer.open({
                type: ,
                title: '批量导出',
                area: ['300px', '210px'],//宽高
                btn: ['导出'],
                yes: function () {
                    var FullName = $('#FullName').val();//供应商全称(筛选条件)
                    var SupplierType = $('#SupplierType').val();//供应商类型(筛选条件)
                    var SupplierLevel = $('#SupplierLevel').val();//供应商级别(筛选条件)
                    var LabMallSupplierIsEnable = $('#LabMallSupplierIsEnable').val();//是否启用(筛选条件)
                    var GoodsHomeShow = $('#GoodsHomeShow').val();//是否显示Log(筛选条件)

                    var ExportType = $("input[name='rdowhere']:checked").val();//导出类型(1:全部;2:筛选)

                    layer.load(, { shade: [0.1, '#000'] });//上传loading

                    $.post("ExportExcelToSupplier", { FullName: FullName, SupplierType: SupplierType, SupplierLevel: SupplierLevel, LabMallSupplierIsEnable: LabMallSupplierIsEnable, GoodsHomeShow: GoodsHomeShow, ExportType: ExportType }, function (res) {
                        layer.closeAll('loading');//关闭loading
                        if (res.success) {
                            layer.close(exportOpen);
                            layer.msg("导出成功");
                            location.href = res.payload;
                        } else {
                            layer.alert(res.error.message, { title: '导出失败' });
                        }
                    }, "json");
                },
                content: html
            });
            layui.form.render();
        }

----------导出功能分为全部导出和按照筛选条件导出
