为什么不直接设置 value 的值呢？
> > 为什么不直接设置 value 的值呢？ > > 因为返回的数据是所有选中的和半选中的id，用value和v-model都无法正确回显值，所以想着用setCheckedKeys方法的第二个参数设置只设置选中的叶子节点状态 > > 另外其实是可以用别的方法解决的，但是发现了这个问题，不知道是bug还是设计如此，所以提了个issue 看了下[源码](https://github.com/element-plus/element-plus/blob/dev/packages/components/tree-select/src/tree.ts#L35-L57)，设置绑定值其实就是调用了 `setCheckedKeys`。Tree 组件没有像 Input 组件一样把父组件 inject 进来，不过特别地将 Tree 组件的方法都暴露出来了，我也不清楚算不算 bug。不过有选中的id，直接设置应该能满足需求的，可以看看这个[Demo](https://element-plus.run/#eyJzcmMvQXBwLnZ1ZSI6IjxzY3JpcHQgc2V0dXAgbGFuZz1cInRzXCI+XG5pbXBvcnQgeyByZWYsIG9uTW91bnRlZCB9IGZyb20gJ3Z1ZSdcbmltcG9ydCB7IEVsZW1lbnRQbHVzIH0gZnJvbSAnQGVsZW1lbnQtcGx1cy9pY29ucy12dWUnXG5jb25zdCB2YWx1ZSA9IHJlZigpXG5jb25zdCBkYXRhID0gcmVmKFtcbiAge1xuICAgIHZhbHVlOiAnMScsXG4gICAgbGFiZWw6ICdMZXZlbCBvbmUgMScsXG4gICAgY2hpbGRyZW46IFtcbiAgICAgIHtcbiAgICAgICAgdmFsdWU6ICcxLTEnLFxuICAgICAgICBsYWJlbDogJ0xldmVsIHR3byAxLTEnLFxuICAgICAgICBjaGlsZHJlbjogW1xuICAgICAgICAgIHtcbiAgICAgICAgICAgIHZhbHVlOiAnMS0xLTEnLFxuICAgICAgICAgICAgbGFiZWw6ICdMZXZlbCB0aHJlZSAxLTEtMScsXG4gICAgICAgICAgfSxcbiAgICAgICAgXSxcbiAgICAgIH0sXG4gICAgXSxcbiAgfSxcbiAge1xuICAgIHZhbHVlOiAnMicsXG4gICAgbGFiZWw6ICdMZXZlbCBvbmUgMicsXG4gICAgY2hpbGRyZW46IFtcbiAgICAgIHtcbiAgICAgICAgdmFsdWU6ICcyLTEnLFxuICAgICAgICBsYWJlbDogJ0xldmVsIHR3byAyLTEnLFxuICAgICAgICBjaGlsZHJlbjogW1xuICAgICAgICAgIHtcbiAgICAgICAgICAgIHZhbHVlOiAnMi0xLTEnLFxuICAgICAgICAgICAgbGFiZWw6ICdMZXZlbCB0aHJlZSAyLTEtMScsXG4gICAgICAgICAgfSxcbiAgICAgICAgXSxcbiAgICAgIH0sXG4gICAgICB7XG4gICAgICAgIHZhbHVlOiAnMi0yJyxcbiAgICAgICAgbGFiZWw6ICdMZXZlbCB0d28gMi0yJyxcbiAgICAgICAgY2hpbGRyZW46IFtcbiAgICAgICAgICB7XG4gICAgICAgICAgICB2YWx1ZTogJzItMi0xJyxcbiAgICAgICAgICAgIGxhYmVsOiAnTGV2ZWwgdGhyZWUgMi0yLTEnLFxuICAgICAgICAgIH0sXG4gICAgICAgIF0sXG4gICAgICB9LFxuICAgIF0sXG4gIH0sXG4gIHtcbiAgICB2YWx1ZTogJzMnLFxuICAgIGxhYmVsOiAnTGV2ZWwgb25lIDMnLFxuICAgIGNoaWxkcmVuOiBbXG4gICAgICB7XG4gICAgICAgIHZhbHVlOiAnMy0xJyxcbiAgICAgICAgbGFiZWw6ICdMZXZlbCB0d28gMy0xJyxcbiAgICAgICAgY2hpbGRyZW46IFtcbiAgICAgICAgICB7XG4gICAgICAgICAgICB2YWx1ZTogJzMtMS0xJyxcbiAgICAgICAgICAgIGxhYmVsOiAnTGV2ZWwgdGhyZWUgMy0xLTEnLFxuICAgICAgICAgIH0sXG4gICAgICAgIF0sXG4gICAgICB9LFxuICAgICAge1xuICAgICAgICB2YWx1ZTogJzMtMicsXG4gICAgICAgIGxhYmVsOiAnTGV2ZWwgdHdvIDMtMicsXG4gICAgICAgIGNoaWxkcmVuOiBbXG4gICAgICAgICAge1xuICAgICAgICAgICAgdmFsdWU6ICczLTItMScsXG4gICAgICAgICAgICBsYWJlbDogJ0xldmVsIHRocmVlIDMtMi0xJyxcbiAgICAgICAgICB9LFxuICAgICAgICBdLFxuICAgICAgfSxcbiAgICBdLFxuICB9XG5dKVxuY29uc3QgdHJlZVJlZiA9IHJlZigpO1xuXG5vbk1vdW50ZWQoKCkgPT4ge1xuICB2YWx1ZS52YWx1ZSA9IFsnMS0xLTEnLCAnMi0xJywgJzMtMi0xJ11cbn0pXG48L3NjcmlwdD5cbjx0ZW1wbGF0ZT5cbiAgPGVsLXRyZWUtc2VsZWN0XG4gICAgcmVmPVwidHJlZVJlZlwiXG4gICAgdi1tb2RlbD1cInZhbHVlXCJcbiAgICA6ZGF0YT1cImRhdGFcIlxuICAgIG11bHRpcGxlXG4gICAgOnJlbmRlci1hZnRlci1leHBhbmQ9XCJmYWxzZVwiXG4gICAgc2hvdy1jaGVja2JveFxuICAvPlxuPC90ZW1wbGF0ZT5cbiIsImltcG9ydC1tYXAuanNvbiI6IntcbiAgXCJpbXBvcnRzXCI6IHt9XG59IiwidHNjb25maWcuanNvbiI6IntcbiAgXCJjb21waWxlck9wdGlvbnNcIjoge1xuICAgIFwidGFyZ2V0XCI6IFwiRVNOZXh0XCIsXG4gICAgXCJqc3hcIjogXCJwcmVzZXJ2ZVwiLFxuICAgIFwibW9kdWxlXCI6IFwiRVNOZXh0XCIsXG4gICAgXCJtb2R1bGVSZXNvbHV0aW9uXCI6IFwiQnVuZGxlclwiLFxuICAgIFwidHlwZXNcIjogW1wiZWxlbWVudC1wbHVzL2dsb2JhbC5kLnRzXCJdLFxuICAgIFwiYWxsb3dJbXBvcnRpbmdUc0V4dGVuc2lvbnNcIjogdHJ1ZSxcbiAgICBcImFsbG93SnNcIjogdHJ1ZSxcbiAgICBcImNoZWNrSnNcIjogdHJ1ZVxuICB9LFxuICBcInZ1ZUNvbXBpbGVyT3B0aW9uc1wiOiB7XG4gICAgXCJ0YXJnZXRcIjogMy4zXG4gIH1cbn1cbiIsIl9vIjp7fX0=)
