js中递归遍历取出deportment、id

 //遍历树形结构 json的递归写法
          traverseTree(node) {
              for (let i=0;i<node.length;i++){
                let element = node[i];
                let depot = {};
                depot.id = element.id;
                depot.name = element.name;
                this.departmentsList.push(depot);
                let children = element.children;
                this.traverseTree(children);
              }
          },复制

json对象封装

                let depot = {};
                depot.id = element.id;
                depot.name = element.name;复制

json对象push数组

                this.departmentsList.push(depot);复制
