<el-tree ref="tree" :data="privilegeList" show-checkbox node-key="id" :default-checked-keys="jurisdictionId" :default-expand-all="true" :props="defaultProps" @check-change="getNode">
</el-tree>
methods: {
// ID, ID
getNode(data) {
console.log("data", data.id);
},
// data
getJurisdictionZtree() {
this.$http.get(this.$api.privilege).then(res => {
this.privilegeList = res.data.data.privilegeList;
console.log("data", this.privilegeList);
});
}
