Vue Js Detect Caps lock Turned On or Not: Vue.js is a JavaScript framework that allows you to build reactive and interactive user interfaces. To detect if the Caps lock is turned on or not, you can use the keyup event and the getModifierState() method of the KeyboardEvent interface.
How can I detect whether the Caps Lock is turned on or off in Vue.js?
This code uses Vue.js to create a web application with an input field that detects whether the user has Caps Lock on. When the user presses a key, the checkCapsLock method is called to check the CapsLock modifier state. If it is on, the capsLockOn property is set to true, and a message is displayed. Otherwise, the message is hidden.
Vue Js Detect Caps lock turned on or not example
<div id="app">
<input type="text" @keydown="checkCapsLock" />
<p v-if="capsLockOn">Caps Lock is on.</p>
</div>
<script type="module">
const app = Vue.createApp({
data() {
return {
capsLockOn: false,
};
},
methods: {
checkCapsLock(event) {
if (event.getModifierState("CapsLock")) {
this.capsLockOn = true;
} else {
this.capsLockOn = false;
}
},
},
});
app.mount('#app');
</script>
