tree组件根据指定属性进行过滤
临时写的，仅供参考
示例，过滤isTrue属性为true的属性，子节点存在匹配数据，会直接将父节点返回
const arr = [
{
id: 1,
name: '1',
isTrue: false,
children: [
{
id: 2,
name: '2',
isTrue: true,
children: [
{
id: 3,
name: '3',
isTrue: true,
children: []
}
]
}
]
}, {
id: 6,
name: '6',
isTrue: true,
children: [
]
}
]
const treeFilter = (list) => { if (!list) { return } return list.filter(item => { item.children = treeFilter(item.children) if (item.children && item.children.length) { return true } else { return item.isTrue == true } }) }
const deptOptions= treeFilter(arr)
