How can I restrict a text field in Vue.js to only allow the input of a maximum of 10 digits/numbers?
The code you provided is a Vue.js component that allows users to input a phone number and limits it to 10 digits. Here's a breakdown of how it works:
-
The
input
element has av-model
directive that binds the input value to thephoneNumber
data property in the Vue instance. This means that any changes made to the input field will update thephoneNumber
value. -
The
input
element also has av-on:input
directive that binds thelimitPhoneNumber
method to the input event. This means that whenever the user types or deletes something in the input field, thelimitPhoneNumber
method will be called. -
The
data
function returns an object with aphoneNumber
property initialized to "1234567890". This sets the initial value of the input field to "1234567890". -
The
limitPhoneNumber
method removes any non-digit characters from thephoneNumber
value using a regular expression (/\D/g
). This ensures that only digits are allowed in the phone number. -
The method then checks if the length of the
phoneNumber
value is greater than 10. If it is, it uses thesubstring()
method to truncate thephoneNumber
value to 10 digits.
So overall, this code limits the phone number input to 10 digits and removes any non-digit characters.
