Answer 1

data() {
return {
visibleBtnAdd: true,
visibleBtnEdit: true,
visibleBtnDelete: true,
formSearch: {
type: undefined,
value: '',
official: undefined
},
formRecord: {
id: null,
name: '',
type: null,
official: true,
waterway: null,
startId: null,
endId: null,
start: null,
end: null,
swzId: null,
remark: '',
waterInfomationPicDTO: []
},
在声明的时候，你的official属性错了，应该为true，希望能给你有些帮助
