请帮我优化这段代码 // 下单 if (this.pWorkOrder.orderState === '20') { this.pWorkOrder.checkRequirements = this.description; } // 接单 if (this.pWorkOrder.orderState === '30') { this.pWorkOrder.checkRequirements = this.description; } // 反馈 if (this.pWorkOrder.orderState === '40') { if (this.pictureDet.length <= 0) { this.$tip.error(`${this.popupSitch.image.label}必填`); return; } this.pWorkOrder.checkRequirements = this.description; this.pWorkOrder.mPicture = this.pictureDet.join(','); } // 审核关闭 if (this.pWorkOrder.orderState === '50') { this.pWorkOrder.checkRequirements = this.description; }

可以将重复的代码提取出来,以减少冗余:
```
this.pWorkOrder.checkRequirements = this.description;
```
然后可以使用 switch 语句来替换多个 if 语句:
```
switch(this.pWorkOrder.orderState) {
case '20':
case '30':
case '50':
this.pWorkOrder.checkRequirements = this.description;
break;
case '40':
if (this.pictureDet.length <= 0) {
this.$tip.error(`${this.popupSitch.image.label}必填`);
return;
}
this.pWorkOrder.checkRequirements = this.description;
this.pWorkOrder.mPicture = this.pictureDet.join(',');
break;
default:
break;
}
```
这样代码就更简洁易读了。

帮我优化这段代码 handleWorkOrderMessage() { // 待办理、待审核二级弹窗 console.log(this.pWorkOrder.orderState); if (this.pWorkOrder.orderState === '20') { this.popupSitch.description.show = true; this.popupSitch.description.label = '经办意见'; this.description = '按要求完成,下单!'; } // 接单 if (this.pWorkOrder.orderState === '30') { this.popupSitch.description.show = true; this.popupSitch.description.label = '经办意见'; this.description = '按要求完成,接单!'; } // 反馈 if (this.pWorkOrder.orderState === '40') { this.popupSitch.description.show = true; this.popupSitch.description.label = '经办意见'; this.popupSitch.image.label = '反馈图片'; this.popupSitch.image.show = true; this.description = '按要求完成,反馈!'; } // 审核关闭 if (this.pWorkOrder.orderState === '50') { this.popupSitch.description.show = true; this.popupSitch.description.label = '经办意见'; this.description = '按要求完成,审核关闭!'; } this.$refs.orderPopup.open(); },
可以尝试以下优化:
1. 将重复的代码提取出来,避免重复写相同的语句。例如,多个条件下都需要设置 `popupSitch.description.show` 为 `true`,可以在代码开头先设置为 `false`,然后根据条件进行修改。
2. 使用 switch 语句替代多个 if 语句,可以让代码更加清晰易懂。
3. 如果有多处使用的字符串,可以将其提取为常量或者变量,方便修改和管理。
下面是优化后的代码示例:
```
handleWorkOrderMessage() {
const DES_LABEL = '经办意见';
const DESC_COMPLETE = '按要求完成,';
const DESC_ORDER = '下单!';
const DESC_ACCEPT = '接单!';
const DESC_FEEDBACK = '反馈!';
const DESC_CLOSE = '审核关闭!';
this.popupSitch = {
description: {
show: false,
label: ''
},
image: {
show: false,
label: ''
}
};
switch (this.pWorkOrder.orderState) {
case '20':
this.popupSitch.description.show = true;
this.popupSitch.description.label = DES_LABEL;
this.description = DESC_COMPLETE + DESC_ORDER;
break;
case '30':
this.popupSitch.description.show = true;
this.popupSitch.description.label = DES_LABEL;
this.description = DESC_COMPLETE + DESC_ACCEPT;
break;
case '40':
this.popupSitch.description.show = true;
this.popupSitch.description.label = DES_LABEL;
this.popupSitch.image.show = true;
this.popupSitch.image.label = '反馈图片';
this.description = DESC_COMPLETE + DESC_FEEDBACK;
break;
case '50':
this.popupSitch.description.show = true;
this.popupSitch.description.label = DES_LABEL;
this.description = DESC_COMPLETE + DESC_CLOSE;
break;
default:
break;
}
this.$refs.orderPopup.open();
},
```
v-if="scope.row.checkInState==='待入住'"怎么同时判断scope.row.orderState==='已支付'
你可以使用逻辑运算符 &&(与)来同时判断两个条件,将它们放在同一个v-if指令中即可,示例代码如下:
```
v-if="scope.row.checkInState==='待入住' && scope.row.orderState==='已支付'"
```
这样,只有当两个条件都满足时,才会渲染指定的元素。
