.net layui 批量導出

.net開發,前臺使用layui框架,後臺使用WCF

廢話很少,直接上代碼

1>文件引用：

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

2>前臺:

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

----------先來個批量導出的按鈕    (ExportExcel)自定義

 

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'://批量導出
                    ShowExportExcelWin();
                    break;
            };
        });    
 });

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

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

----------ShowExportExcelWin  //方法名

//打開批量導出彈窗
        var exportOpen;
        function ShowExportExcelWin() {
            var $ = layui.jquery;
            var html = '<div class="layui-form">';
            html += '   <div class="layui-form-item">';

            html += '           <input type="radio" name="rdowhere" value="2" title="按篩選條件導出" >';
            html += '       </div>';
            html += '   </div>';
            html += '</div>';
            exportOpen = layer.open({
                type: 1,
                title: '批量導出',
                area: ['300px', '210px'],//寬高

                    var SupplierLevel = $('#SupplierLevel').val();//供應商級別(篩選條件)
                    var LabMallSupplierIsEnable = $('#LabMallSupplierIsEnable').val();//是否啓用(篩選條件)
                    var GoodsHomeShow = $('#GoodsHomeShow').val();//是否顯示Log(篩選條件)

                    var ExportType = $("input[name='rdowhere']:checked").val();//導出類型(1:所有;2:篩選)

                    layer.load(2, { shade: [0.1, '#000'] });//上傳loading

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

----------導出功能分爲所有導出和按照篩選條件導出
