Vue Js Character Count | Show Remaining Character : To implement character count functionality for input fields in a Vue.js application, you can define a computed property that calculates the remaining characters based on the difference between the maximum allowed length and the current length of the input value. This computed property can be bound to a data property that stores the input value, and the remaining characters count can be displayed in the UI. You can also add a validation check to prevent the user from entering more characters than the maximum allowed length. Finally, you can use event listeners to update the remaining characters count whenever the user types or deletes characters in the input field.
How to Count Character in Textarea using Vue JS?
This is a Vue.js app that counts the number of characters in a text area. It uses two-way data binding to update the character count as the user types. The app is created with a data object that holds the input text and the character count, and a method that updates the character count based on the input text length. The character count is displayed below the text area.
Vue Js Character Count | Example
<div id="app">
<h3>Vue Js Character Count</h3>
<textarea type="text" v-model="inputText" @input="updateCharCount"></textarea>
<p v-if="inputText">Character count: {{ charCount }}</p>
</div>
<script type="module">
import { createApp } from "vue";
createApp({
data() {
return {
inputText: '',
charCount: 0
}
},
methods: {
updateCharCount() {
this.charCount = this.inputText.length
}
}
}).mount("#app");
</script>

How to Show Remaining Character in Vue Js?
- The Vue.js application has a template with a heading, a label, a text area, and a div element that displays the remaining number of characters that can be typed in the text area.
- The text area has two bindings,
v-model
and:maxlength
. v-model
binds the value of the text area to theinputValue
data property in the Vue.js application.:maxlength
sets the maximum length of the text that can be entered in the text area to the value of themaxLength
data property in the Vue.js application.- The Vue.js application has a
data
object that contains theinputValue
andmaxLength
properties. - The
inputValue
property is initialized to an empty string, and themaxLength
property is set to 10. - The Vue.js application has a
computed
property calledremainingChars
. - The
remainingChars
property calculates the remaining number of characters that can be typed in the text area by subtracting the length of theinputValue
property from themaxLength
property. - The
remainingChars
property is displayed in the div element using Vue.js template syntax.
