Vue Textarea maxlength:In Vue, the maxlength attribute is used to set a maximum length limit for a textarea element. This attribute specifies the maximum number of characters that can be entered in the textarea. When the user types in the textarea, Vue checks the length of the input and prevents the user from typing any more characters once the maximum limit has been reached. This is useful for enforcing character limits in forms or input fields. Additionally, Vue provides a way to dynamically bind the maxlength attribute to a data property, allowing the limit to be adjusted based on certain conditions or user input.
How can I set a maximum character limit for a textarea in a Vue js?
This Vue.js code creates a textarea element with a maximum length of 20 characters. The remaining number of characters that can be typed in the textarea is displayed using a computed property that subtracts the length of the message from the maximum length.
Vue Textarea maxlength Example
<div id="app">
<h3>Vue Textarea maxlength</h3>
<textarea v-model="message" maxlength="20"></textarea>
<p>{{ remainingCharacters }} characters remaining</p>
</div>
<script type="module">
const app = Vue.createApp({
data() {
return {
message: '',
maxLength: 20
}
},
computed: {
remainingCharacters() {
return this.maxLength - this.message.length
}
}
});
app.mount('#app');
</script>
