Display validation messages when the user either clicks out of the textbox or finishes typing

Here are some validation messages:

<form name="dnaform" novalidate>
    <div style="padding-bottom:5px" ng-show="dnaform.uEmail.$pristine || dnaform.uEmail.$valid">Active directory account </div>
    <div style="padding-bottom:5px;" ng-show="dnaform.uEmail.$dirty && dnaform.uEmail.$error.required" class="help-block">Email is Required.</div>
    <div style="padding-bottom:5px;" ng-show="dnaform.uEmail.$error.email" class="help-block">Invalid Email.</div>
    <input type="email" name="uEmail" class="form-control txtBoxEdit type7N" ng-model="useremail" required>
</form>

The issue I'm facing is that the validation message appears instantly when the user starts typing in the email textbox. My goal is to display the message only after the user has entered a full email or moves focus away from the textbox.

Answer №1

Don't forget to create a function that will be triggered when the input loses focus. You can refer to this example

$scope.onBlur = function() {

    };

Make sure to implement this function for the blur event on your input element

<input type="text" ng-blur="onBlur(inputData)" ng-model="inputData">

Answer №2

Utilize the $touched property:

<div style="padding-bottom:5px;" ng-if="dnaform.uEmail.$touched && dnaform.uEmail.$error.email" class="help-block">Invalid Email.</div>

According to the documentation:

  1. ng-touched: indicates that the control has been blurred, meaning once it is touched, validation will occur on subsequent occasions. To avoid this, add it to your <input>:
ng-model-options="{ updateOn: 'blur' }"

Code snippet:

(function() {
  'use strict';
  angular.module('app', [])
    .controller('mainCtrl', function($scope) {

    })
})();
<!DOCTYPE html>
<html ng-app="app">

<head>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.7/angular.min.js"></script>
</head>

<body ng-controller="mainCtrl">
  <form name="dnaform" novalidate>
    <div style="padding-bottom:5px" ng-show="dnaform.uEmail.$pristine || dnaform.uEmail.$valid">Active directory account </div>
    <div style="padding-bottom:5px;" ng-show="dnaform.uEmail.$dirty && dnaform.uEmail.$error.required" class="help-block">Email is Required.</div>
    <div style="padding-bottom:5px;" ng-if="dnaform.uEmail.$touched && dnaform.uEmail.$error.email" class="help-block">Invalid Email.</div>
    <input type="email" name="uEmail" ng-model-options="{ updateOn: 'blur' }" class="form-control txtBoxEdit type7N" ng-model="useremail" required>
</form>
</body>

</html>
