做權(quán)限控制，根據(jù)后臺(tái)傳回來的權(quán)限，對(duì)樹形表做選中顯示設(shè)置checked=true,是可以的。權(quán)限改變?cè)O(shè)置checked=false,就會(huì)更改失敗，checked還是為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{
