[Vuejs]-How to execute a method of a nested component

In most cases you want to avoid doing this if possible. Data should flow down and events should be emitted up.

That being said you can access by adding a ref to the child. In child you add a

<Child ref='foo'></>

Then in your parent you access the component vie ‘this.$refs.foo’ which will have all the normal method and data stuff on the child.
