树形数据源

 options:[{ancestors: "0",code: "99",id: "99",name: "测试部门1",parentId: "0",children: [{ancestors: "0,99",code: "test",id: "1720269456426344449",name: "测试子部门1",parentId: "99",children: [{ancestors: "0,99",code: "ccc",id: "17202694564263444491",name: "测试子部门12",parentId: "1720269456426344449",},},{ancestors: "0,99",code: "102",id: "1560428307109957633",name: "测试子部门2",parentId: "99"},{ancestors: "0,99",code: "104",id: "1560428634399887362",name: "测试子部门3",parentId: "99"},]}],

定义递归函数

//递归getTreeName(list, id) {for (let i = 0; i < list.length; i++) {if (list[i].id === id) {return list[i].name} else if (list[i].children && list[i].children.length > 0) {let res = this.getTreeName(list[i].children, id)if (res) {return res}}}}

定义调用函数

      //树形回显streetFormat(item, params) {return this.streetType(params, item);},// 回显streetType(datas, value) {var actions = [];actions.push(this.getTreeName(datas, value))return actions.join('');},

调用函数

<span v-else-if="item.type === 'street'">{{ streetFormat(row[item.name],item.param) }}
</span>

至此回显成功
