問題1:選中子級時默認選中父級
<el-tree :data="menuData" show-checkbox default-expand-all node-key="id" :props="defaultProps" ref="menuTree" :render-content="renderContent" :expand-on-click-node="false"> </el-tree> //提交 submitRole(){ // 點擊子級時默認也選中父級Id傳給后台concat合並
//this.$refs.menuTree.getCheckedKeys()獲取子級id
//this.$refs.menuTree.getHalfCheckedKeys()獲取父級id
var checkKeys = this.$refs.menuTree.getCheckedKeys().concat(this.$refs.menuTree.getHalfCheckedKeys());
let newArr = checkKeys.map(item => { return { menuId: item, roleId: this.roleId } });
let lists= { lists:newArr }
roleImpower(lists).then(res=>{
if(res.code ==200){ this.$message.success("授權成功"); }
else{ this.$message.error("授權失敗"); } })
console.log(newArr)
this.roleDia = false
},
問題2:回顯有父級id,默認選中父級下所有子級
// 組授權 handleAuth(id){
//獲取回顯的id
getRoleId(id).then(res=>{ let that = this if (res.data.lists) { setTimeout(function () { res.data.lists.forEach((value)=>{ that.$refs.menuTree.setChecked(value,true,false) }) },200);
//用下面方法,回顯帶有父級id,會默認選中所有子級, // var aaa = this.$refs.menuTree.setCheckedKeys(res.data.lists) } }) this.roleId = id //回顯權限列表 allMenu(this.listQuery).then(res => { this.loading = false this.menuData = res.data.menu || [] }, error => { this.loading = false this.$message.error(error.message) }) this.roleDia = true },
