先上代码

   const groupedOptions = {} // 使用对象来存储分组结果data.list.forEach(item => {
// 遍历 groupList.value，检查是否有匹配的 idgroupList.value.forEach(group => {if (group.id === item.groupId) {// 如果 group.id 在 groupedOptions 中不存在，则初始化它if (!groupedOptions[group.groupName]) {groupedOptions[group.groupName] = []}// 将当前 item 添加到匹配的组中groupedOptions[group.groupName].push({value: item.id,label: item.nickName,})}})})// 将 groupedOptions 转换为 options.value 所需的格式options.value = Object.keys(groupedOptions).map(groupName => ({label: groupName,options: groupedOptions[groupName],}))

我这个主要处理这个问题 （groupList）

[{"id": "1","groupName": "xxx","userId": "1251139989602463744","createTime": "1718594337191","updateTime": "1718594337191","channel": 3},{"id": "2","groupName": "bbb","userId": "1251139989602463744","createTime": "1718441669851","updateTime": "1718441669851","channel": 3},{"id": "3","groupName": "ccc","userId": "1251139989602463744","createTime": "1718441665340","updateTime": "1718441665340","channel": 3}
]

data.list

[{"id": "1252211435414130688","nickName": "闪电票务","groupId": "1","customerId": "0",{"id": "1251590257989292032","nickName": "xxx","groupId": "1",},{"id": "1251590257989292032","nickName": "ccc","groupId": "3",},{"id": "1251590257989292032","nickName": "xxx","groupId": "2",},{"id": "1251590257989292032","nickName": "xxx","groupId": "2",},{"id": "1251590257989292032","nickName": "xxx","groupId": "3",},]

把这个分组 一下 放在一起 变成这样的数据

[{label: 'Manager',options: [{value: 'jack',label: 'Jack',},{value: 'lucy',label: 'Lucy',},],},{label: 'Engineer',options: [{value: 'yiminghe',label: 'Yiminghe',},],},]
