## 场景 ##

在进行新增和编辑时，如果后台有传递到前端值，则根据值的内容选中下拉框。

## 实现 ##

<select class="form-control" name="businessInitiator"  id="businessInitiator">
                                                <option  id="yuanliaoInitiator" th:selected="${refundOrder != null && refundOrder.businessInitiator != null && refundOrder.businessInitiator  == '原料立库'}" value="原料立库"><span th:text="原料立库"></span></option>
                                                <option  id="qingjieInitiator" th:selected="${refundOrder != null && refundOrder.businessInitiator != null && refundOrder.businessInitiator  == '清洁车间'}" value="清洁车间"><span th:text="清洁车间"></span></option>
                                                <option  id="zhengjiInitiator" th:selected="${refundOrder != null && refundOrder.businessInitiator != null && refundOrder.businessInitiator  == '正极车间'}" value="正极车间"><span th:text="正极车间"></span></option>
                                                <option  id="fujiInitiator" th:selected="${refundOrder != null && refundOrder.businessInitiator != null && refundOrder.businessInitiator  == '负极车间'}" value="负极车间"><span th:text="负极车间"></span></option>
             <option value="" disabled selected hidden>选择退货发起方</option>
                                            </select>

后台返回数据代码：

@Description("获取新增或者编辑界面")
        @RequestMapping("/toAddRefundOrder")
        public String toAddRefundOrder( int id, Model model){
            if ( id != 0){
                //如果是编辑操作，查询出当前退货单
                WmsRefundOrder refundOrder = refundOrderService.getById(id);
                model.addAttribute("refundOrder",refundOrder);
            }
            return "refund/addRefundOrder.html";
        }
