How to Implement Input Masking in Vue.js?
The given code is a Vue.js application which performs the following actions:
-
HTML Template:
- A div is created with an ID of "app", which contains an input field for entering a phone number.
- The input field is bound to a data property "formattedPhoneNumber" using the v-model directive.
- An @input event is attached to the input field that triggers the "formatPhoneNumber" method.
-
JavaScript Code:
- A new instance of Vue is created, which consists of:
- el: A string that specifies the div with ID "app" as the element that the Vue app is bound to.
- data: An object containing two properties, "rawPhoneNumber" and "formattedPhoneNumber", used to store the phone number entered by the user.
- methods: An object containing two methods:
- formatPhoneNumber: This method takes the current value of the input field and updates the "rawPhoneNumber" data property with it. It then formats the "formattedPhoneNumber" using the "formatAsPhoneNumber" method.
- formatAsPhoneNumber: This method takes the value of "rawPhoneNumber", removes all non-numeric characters, limits it to 10 characters, and formats it as -XXX- XXX-XXXX.
- A new instance of Vue is created, which consists of:
The user can enter a phone number in the input field, and the app will automatically format it as XXX- XXX-XXXX.
