how can component delete itself in Vue 2.0
I couldn't find instructions on completely removing a Vue instance, so here's what I wound up with:
module.exports = {
...
methods: {
close () {
// destroy the vue listeners, etc
this.$destroy();
// remove the element from the DOM
this.$el.parentNode.removeChild(this.$el);
}
}
};
Vue 3 is basically the same, but you'd use root
from the context argument:
export default {
setup(props, { root }){
const close = () => {
root.$destroy();
root.$el.parentNode.removeChild(root.$el);
};
return { close };
}
}
In both Vue 2 and Vue 3 you can use the instance you created:
const instance = new Vue({ ... });
...
instance.$destroy();
instance.$el.parentNode.removeChild(instance.$el);
No, you will not be able to delete a component directly. The parent component will have to use v-if
to remove the child component from the DOM.
Ref: https://v2.vuejs.org/v2/api/#v-if
Quoted from docs:
Conditionally render the element based on the truthy-ness of the expression value. The element and its contained directives / components are destroyed and re-constructed during toggles.
If the child component is created as part of some data object on parent, you will have to send an event to parent via $emit
, modify (or remove) the data and the child component will go away on its own. There was another question on this recently: Delete a Vue child component
