Use of @blur in Vue 3:
The @blur event listener in Vue 3 is utilized to capture events when an element loses focus. This is particularly useful for scenarios where you want to perform an action or validation after the user has completed input in a field, such as validating a form field or formatting data.
Example:
Imagine a scenario where you want to format a date input after the user has completed typing:
<template>
<input v-model=”userDate” @blur=”formatField(‘userDate’)” />
</template>
<script>
export default {
data() {
return {
userDate: “”
};
},
methods: {
formatField(fieldName) {
// Your formatting logic here
// Update data or perform actions after the user finishes typing
}
}
};
</script>
Here, the @blur event triggers the formatField method, which can contain logic to format the date or perform any other necessary actions after the user finishes entering the date.
