Use of @input in Vue 3:
The @input event listener in Vue 3 is employed to capture and respond to user input events, making it an indispensable tool for interactive web development. It is commonly associated with input elements, such as textboxes or textarea, and allows developers to respond dynamically as users type, providing real-time feedback and enabling a dynamic user interface.
Example:
Suppose you have an input field for a loan amount, and you want to validate and update the loan amount as the user types:
<template>
<input v-model=”loanAmount” @input=”validateDecimal(‘loanAmount’)” />
</template>
<script>
export default {
data() {
return {
loanAmount: “”
};
},
methods: {
validateDecimal(fieldName) {
// Your validation logic here
// Update data or perform actions based on user input
}
}
};
</script>
In this example, the @input event triggers the validateDecimal method, which can contain logic to validate the loan amount and perform any necessary actions based on user input.
