Tree组件子节点不完全勾选获取父节点的值

### 父节点如果有回显的情况下 1.循环遍历出最深层子节点，存放在一个数组中 2.将后台返回的含有父节点的数组和第一步骤遍历的数组做比较 3.如果有相同值，将相同值取出来，push到一个新数组中 4.利用这个新的重组的数组给Tree组件selected赋值 ``` const deepArr = [] //deepArr存放所有子节点的数组 //第一步骤：子节点放在一个数组中 const requestList = (data) => { data && data.map(item => { if (item.children && item.children.length > 0) { requestList(item.children) } else { deepArr.push(item.id) } return null }) return deepArr } //第2，3步骤的方法 const uniqueTree = (uniqueArr, Arr) => { let uniqueChild = [] for (var i in Arr) { for (var k in uniqueArr) { if (uniqueArr[k] === Arr[i]) { uniqueChild.push(uniqueArr[k]) } } } return uniqueChild } //调用第2，3步骤的方法 const getRoleInfo = () => { getData({ id: Id }).then(res => { const ids = res.data const uniqueChild = this.uniqueTree(ids, deepArr) setCheckedKeys(uniqueChild) }) } <Tree checkable checkedKeys={checkedKeys} defaultExpandedKeys={checkedKeys} fieldNames={{ title: 'name', key: 'id' }} treeData={menuList} /> ```
