Vue Js Textbox allow only capital letter
Vue Js Textbox allow only capital letter:To allow only capital letters in a Vue.js textbox using regex, you can use the @input
event to capture the input and update the textbox value based on a regular expression match. Inside the onInput
method, you can use the RegExp.test()
method with the regular expression /^[A-Z]*$/
to check if the input consists of only capital letters. If it doesn't match, you can set the textbox value to an empty string. This ensures that only capital letters are allowed in the textbox.

How can I create a Vue.js textbox that only accepts capital letters?
The provided code snippet demonstrates how to create a textbox in Vue.js that allows only capital letters.
The code sets up a Vue application with an input element bound to the inputValue
data property using v-model
. The handleInput
method is triggered whenever the input value changes.
Inside the handleInput
method, a regular expression is used to check if the input consists of only capital letters. If it does not match the pattern, the isInputValid
property is set to false
, and an error message is displayed.
Additionally, the method removes any non-capital letters from the input by replacing them with an empty string using the replace
function and a regular expression.
