一分钟实现 layui 导出 excel --php--laravel

layui导出Excel三步走：

一、第1步：导出按钮 ;

 <button  type="button" class="layui-btn layui-btn-sm" id="export">导出</button>

 

二、第2步：table.render中加入toolbar和totalrow属性都设置为true;

        官方文档也有说过如图： 

代码截图

 贴代码： 

 layui.use(['layer','table','form','laydate', 'excel'],function () {
                var layer = layui.layer;
                var excel = layui.excel;
                var form = layui.form;
                var table = layui.table;
                var $ = layui.$;
                //用户表格初始化
                var dataTable = table.render({
                    elem: '#dataTable'
                    ,height: 500
                    ,url: "{{ route('admin.agent_apply.data') }}" //数据接口
                    ,page: true //开启分页
                    // ,toolbar: '#toolbar'
                    ,toolbar:true
                    ,title:'推荐官申请列表'
                    ,totalRow:true
                    ,cols: [[ //表头
                        {checkbox: true,fixed: true}
                        ,{field: 'id', title: 'ID', sort: true,width:80}

三、第3步：JS请求接口拿到数据导出 

               $("#export").click(function (obj) {
                    $.get(
                        "{{ route('admin.agent_apply.export') }}",
                        {
                            _method:'get',
                            'id' :$("input[name='id']").val(),
                            'mobile' : $("input[name='mobile']").val(),
                            'status' : $("select[name='status']").val(),
                            'start_time' : $("input[name='start_time']").val(),
                            'end_time' : $("input[name='end_time']").val(),
                            'type' : $("select[name='type']").val(),
                        },
                        function (result) {
                            excel.exportExcel({
                                sheet1: result
                            }, '推荐官申请列表.xlsx', 'xlsx')
                        });
                })

注意：

       数据返回数组格式为：

$data = [
    ['学号','姓名','成绩'],
    ['10001','AAAAA','99'],
    ['10002','BBBBB','92'],
    ['10003','CCCCC','95'],
    ['10004','DDDDD','89'],
    ['10005','EEEEE','96'],
];

（即二维数组中第一个子数组为excel标题栏，下面数据一一对应）

php接口代码示例：

/**
     * @param Request $request
     * @return array
     * 导出
     */
    public function export(Request $request)
    {
        $params = $request->all();
        $query  = self::_where($params);
        $res    = $query->orderBy('id', 'desc')
            ->with('sku')
            ->with('dealer')
            ->with('address_info')
            ->with('coupon')
            ->get()
            ->toArray();
        $rs     = [];
        if ($res) {

                $rs[$k][] = floatFormat($v['fee']);
                $rs[$k][] = floatFormat($v['balance']);
                $rs[$k][] = floatFormat($v['goods_price']);
                $rs[$k][] = floatFormat($v['sku']['cost_price']);
                $rs[$k][] = floatFormat($v['sku']['line_price']);
                $rs[$k][] = $v['goods_attr'];

                $rs[$k][] = $v['area_name'];
                $rs[$k][] = $v['address'];
                $rs[$k][] = $v['remark'];
                $rs[$k][] = $v['user_id'];
                $rs[$k][] = SubOrders::IS_REFUND_TXT[$v['is_refund']];
                $rs[$k][] = $v['coupon_id'];
                $rs[$k][] = $v['coupon']['title'] ?? '';

            }
        }
        $data[] = ["母订单", "订单号", "支付流水号", "订单来源", '订单状态', '订单创建时间', '订单付款时间', '订单发货时间', '确认收货时间', 'SKU_ID', 'SKU编码', '供应商简称', '供应商公司名称', '商品名称', '数量', '实付金额', '三方支付', '余额支付', '商品价（单价）', '成本价（单价）', '划线价（单价）', 'SKU规格', '收件人姓名', '收件人手机号', '收件人省份', '收件人城市', '收件人区/镇', '收件人具体地址', '备注', '用户ID', '售后状态', '优惠券ID', '优惠券名称'];
