Click the button in the above component to regret mounting the user subcomponent instance to div , and then add div to list . user.vue is as follows:

<template>..</template>
<script>
export default {
    data () {
        return {
            say: "nihao"
        };
    } , 
    props: ["__id__"] , 
    inject: ["find"] , //  vue 
    mounted () {
         this.$nextTick(() => {
             console.log(this.$parent); // undefined
             console.log(this._testid_); // undefined
             console.log(this.__id__); // testid
             console.log(this.find); // undefined 
         });
    }
};
</script>

is a child component created by Vue.extend , without context (without the concept of parent component, it is an independent component individual), can only transfer data through propsData (of course, you can also use global things, do not consider.) ?
