这段代码与前面的代码类似,但是它检查的是`messageBody.alarmState`是否等于"1"。如果是,它会生成一个通知ID并将其存储在`notifications`数组中。如果`notifications`数组中只有一个元素,则会播放一段音频。然后,它会使用`ElNotification`组件创建一个成功类型的通知消息,并在关闭通知时更新`notifications`数组。如果`notifications`数组为空,则会停止播放音频。因此,这段代码用于处理设备状态为1时的通知和警报逻辑。

let notifications = []; if (messageBody.alarmState === "0") { const notificationId = Date.now(); notifications.push(notificationId) if (notifications.length === 1) { audio.play(); } const errorMessage = "设备名称: " + messageBody.equipmentName + '<br>' ElNotification({ message: errorMessage, dangerouslyUseHTMLString: true, type: 'warning', customClass: 'my-notification-warning',// 添加自定义类名 onClose: function () { notifications = notifications.filter(function(n) { return n !== notificationId; }); if (notifications.length === 0) { audio.pause(); audio.currentTime = 0; } } }) }
这段代码看起来像是处理推送通知和警报的逻辑。当`messageBody.alarmState`等于"0"时,会生成一个通知ID并将其存储在`notifications`数组中。如果`notifications`数组中只有一个元素,则会播放一段音频。接着,会使用`ElNotification`组件创建一个警告类型的通知消息,并在关闭通知时更新`notifications`数组。如果`notifications`数组为空,则会停止播放音频。我的回答是否符合您的问题?
delOrPromptbox = x => { if (x.length == 0) { this.promptBox('warn', '请选择要删除的数据!'); } else { this.del(x); } }; async delete(row) { if (row.id == 'itemSubmit' && row.label == '批量删除') { const uriIdList = this.tableObjSubmit.checkedList.map(x => x['uriId']); this.delOrPromptbox(uriIdList); } else if (row.id == 'itemCom' && row.label == '批量删除') { const uriIdList = this.tableCom.checkedList.map(x => x['uriId']); this.delOrPromptbox(uriIdList); } else if (row.id == 'itemHistory' && row.label == '批量删除') { const uriIdList = this.tableHistory.checkedList.map(x => x['uriId']); this.delOrPromptbox(uriIdList); } else { this.del([row.uriId]); } }优化这段代码
你可以对这段代码进行优化,将重复的部分提取出来,减少代码重复。可以按照以下方式进行优化:
```javascript
delOrPromptbox = x => {
if (x.length == 0) {
this.promptBox('warn', '请选择要删除的数据!');
} else {
this.del(x);
}
};
async delete(row) {
let uriIdList;
if (row.label == '批量删除') {
if (row.id == 'itemSubmit') {
uriIdList = this.tableObjSubmit.checkedList.map(x => x['uriId']);
} else if (row.id == 'itemCom') {
uriIdList = this.tableCom.checkedList.map(x => x['uriId']);
} else if (row.id == 'itemHistory') {
uriIdList = this.tableHistory.checkedList.map(x => x['uriId']);
}
this.delOrPromptbox(uriIdList);
} else {
this.del([row.uriId]);
}
}
```
在优化后的代码中,通过提取重复的部分代码,使得逻辑更加清晰和简洁。
