do permission control, and it is possible to select and display the tree table and set checked=true, according to the permissions sent back by the background. If you change the permission setting, the checked=false, will fail, and the checked will still be true

this.permissionTree[0].children.forEach((item, index) => {
                if (item.children.length>=0) {
                    let childrenArr = [];
                    childrenArr = item.children.filter(child => {
                        if (child.permission !== undefined) {
                            if (role.permissions.indexOf(child.permission) >= 0) {
                                child.checked = true;
                            }else{
                                child.checked = false;
                            };
                            return child;
                        } else {
                            return child;
                        }
                    });
                    if(childrenArr.length>0){
                        item.children=childrenArr;
                        permissionTreeList.push(item);
                    }   
                    console.info("childrenArr",childrenArr)                
                }                
            });
