Tp+JQuery优惠券添加

效果图展示：

控制器代码：

    // 获取当前页面优惠券类型参数
    public function getParams(){
        $result = [
            'status' => false,
            'msg'    => '',
            'data'   => '',
        ];
        $this->view->engine->layout(false);
        $typeId = input('post.typeId');
        if ($typeId) {
            $html             = $this->fetch('getParams_'.$typeId);
            $result['status'] = true;
            $result['msg']    = '获取成功';
            $result['data']   = $html;
        }
        return $result;
    }

 模型层代码：（展示部分处理）

            if (isset($val['coupon_type']) && $val['coupon_type'] == 1){
                $str = '满减券-';
                if (isset($val['doorsill']) && $val['doorsill'] == 1){
                    if (isset($val['moneyoff'])){
                        $str .= "减".$val['moneyoff']."元";
                    }
                }elseif (isset($val['doorsill']) && $val['doorsill'] == 2){
                    if (isset($val['moneyoff']) && isset($val['full'])){
                        $str .= "订单满".$val['full']."元减".$val['moneyoff']."元";
                    }
                }
                $val['desc'] = $str;
            }elseif (isset($val['coupon_type']) && $val['coupon_type'] == 2){
                $str = '折扣券-';
                if (isset($val['doorsill']) && $val['doorsill'] == 1){
                    if (isset($val['privilege']) && !empty($val['privilege'])){
                        $str .= "打".$val['discount']."折，最多优惠".$val['privilege']."元";
                    }else if (isset($val['discount']) && !empty($val['discount'])){
                        $str .= "打".$val['discount']."折";
                    }
                }elseif (isset($val['doorsill']) && $val['doorsill'] == 2){
                    if (isset($val['privilege']) && $val['privilege']){
                        $str .= "订单满".$val['full']."元，打".$val['discount']."折，最多优惠".$val['privilege']."元";
                    }else if (isset($val['discount']) && isset($val['full']) && !empty($val['full'])){
                        $str .= "订单满".$val['full']."元，打".$val['discount']."折";
                    }
                }
                $val['desc'] = $str;
            }else if (isset($val['coupon_type']) && $val['coupon_type'] == 3){
                $str = '商品券-';
                if (isset($val['doorsill']) && $val['doorsill'] == 1){
                    if (isset($val['deduction'])){
                        $str .= "抵扣".$val['deduction']."元";
                    }
                }elseif (isset($val['doorsill']) && $val['doorsill'] == 2){
                    if (isset($val['deduction']) && isset($val['full']) && !empty($val['full'])){
                        $str .= "订单满".$val['full']."元，抵扣".$val['deduction']."元";
                    }
                }
                $val['desc'] = $str;
            }

view视图层展示：（根据选择优惠券类型   会展示不同的类型方式字段）

view视图层添加页面代码：

   <div class="layui-form-item">
        <label class="layui-form-label">优惠券类型：</label>
        <div class="layui-input-inline">
            <select name="coupon_type" id="coupon_type" required  lay-verify="required" lay-filter="coupon_type">
                <option value="">请选择优惠券类型</option>
                <option value="1">满减券</option>
                <option value="2">折扣券</option>
                <option value="3">商品券</option>
            </select>
        </div>
    </div>

    <script>

        form.on('select(coupon_type)', function(data) {
            var type_id = data.value;
            console.log("type_id:", type_id)
            if (type_id) {
                layer.confirm('更换优惠券类型后，货品需重新生成，确定要更换吗？', {
                    btn: ['确定', '取消'],
                    title: '提示',
                }, function(index) {
                    layer.close(index);
                    JsPost('{:url("Coupon/getParams")}', {
                        'typeId': type_id,
                    }, function(e) {
                        if (e.status === true) {
                            $("#coupon_type_html").html(e.data);
                        } else {
                            layer.msg(e.msg);
                        }
                    });
                }, function() {});
            }
        });

     </script>
