Vue Js Character Limit with Error Messages in Vue.js Input Fields: Text length limits with Vue.js input validation and error messages refer to a feature that ensures that the user’s input in text fields does not exceed a specified maximum length. This helps to maintain the integrity and accuracy of the data being entered, and provides a better user experience by preventing confusion or errors that may result from overly long inputs.
How can input text length be validated and error messages be displayed in Vue.js?
- Bind the input field to the
textdata property usingv-model - Set the
maxlengthattribute to 10 (or desired maximum length) - Display the number of characters currently entered using
text.length - Show the user how many more characters they can enter
- Return an error message if the input exceeds the maximum length
Vue.js input validation ensures max length, prevents errors, and displays error messages.
<div id="app">
<input type="text" v-model="text" required/><br>
<Pre :style="{ color: text.length>10 ? 'red' : 'initial' }"><span v-if="text.length > 10">{{ errorMessage }}.</span>Total text length {{text.length}}</Pre>
</div>
<script type="module">
const app = new Vue({
el: "#app",
data() {
return {
text: '',
errorMessage: 'Error: Length exceeded, max allowed 10'
}
},
});
</script>
