Vue 'beforeUnmount' Lifecycle Hook
Example
Using the beforeUnmount lifecycle hook to create an alert with text taken from inside a <p> element.
<script>
export default {
beforeUnmount() {
alert("beforeUnmount: The text inside the p-tag is: " + this.$refs.pEl.innerHTML);
}
}
</script>
Definition and Usage
The beforeUnmount lifecycle hook happens right before the component is removed from the DOM.
When running code in the beforeUnmount hook, the component is still fully functional.
