It is recommended to read the document again and see the scope of the component
props: ['tip'] should be written in var tipTemplate={} instead of new Vue({}). The scope of the component is wrong
There is a problem with the answer above. Components need dynamic attribute binding:
The whole is as follows:
Add a v-if="tip" to the child component
