The blur event is actually called the focusout event. It happens when an element has focus and then loses it.
(Hint: Click around to different inputs or click in one and wail on the tab key.)
<script> export default { methods: { onBlurOutside(e, el) { console.log("onBlurOutside"); console.log("Event:", e); console.log("Element focus was given to:", e.target); console.log("Element smugly watching:", el); } } } </script>
