How can we make show/hide password input in angular js with bootstrap 3?

Question

I want to make show/hide password input in angularjs with Bootstrap 3.

The toggle option needs to be inside the input.

Can you provide a snippet or example on that.

Thanks a million.

Solution 1

You can dynamically change the input type with the ng-attr-type directive. For example:

<input ng-attr-type="{{ showPassword ? 'text' : 'password' }}">

you can tie the showPassword to the click event and make it toggle.

Update (from @Ferie's comment):

HTML

<span class="showPassword" ng-click="togglePassword()">{{ typePassword ? 'Hide' : 'Show' }}</span><br> <input type="{{ typePassword ? 'text' : 'password' }}" name="password" placeholder="Password"> 

In the Angular Controller

$scope.togglePassword = function () { $scope.typePassword = !$scope.typePassword; };

AngularJS / UI Bootstrap Solution

• Use Bootstrap's has-feedback class to show an icon inside the input field.
• Make sure the icon has style="cursor: pointer; pointer-events: all;"
• Use ng-if to show/hide different forms where the <label type="password"> vs <label type="text">

HTML

<!-- index.html snippet -->    

<!-- show password as type="password" -->
<div ng-if="!showPassword"
       class="form-group has-feedback">
    <label>password</label>
    <input type="password"
           ng-model="params.password"
           class="form-control"
           placeholder="type something here...">
    <span ng-if="params.password"
          ng-click="toggleShowPassword()"
          class="glyphicon glyphicon-eye-open form-control-feedback" 
          style="cursor: pointer; pointer-events: all;">
    </span>
  </div>

  <!-- show password as type="text" -->
  <div ng-if="showPassword"
       class="form-group has-feedback">
    <label>password</label>
    <input type="text"
           ng-model="params.password"
           class="form-control"
           placeholder="type something here...">
    <span ng-if="params.password"
          ng-click="toggleShowPassword()"
          class="glyphicon glyphicon-eye-close form-control-feedback" 
          style="cursor: pointer; pointer-events: all;">
    </span>
  </div>

JavaScript

// app.js

var app = angular.module('plunker', ['ui.bootstrap']);

app.controller('MainCtrl', function($scope) {
    $scope.params = {};
    $scope.showPassword = false;
    $scope.toggleShowPassword = function() {
        $scope.showPassword = !$scope.showPassword;
    }
});

Give it as spin with the plunker: http://plnkr.co/edit/oCEfTa?p=preview

Solution 3

you can simply do

<input ng-show="showpassword" type="text" ng-model="password">
<input ng-hide="showpassword" type="password" ng-model="password">
<input type="checkbox" ng-model="showpassword" ng-checked="false">

Here's a working demo:

var app = angular.module('myApp', []);
app.controller('loginCtrl', function($scope) {
  $scope.showPassword = false;

  $scope.toggleShowPassword = function() {
    $scope.showPassword = !$scope.showPassword;
  }

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<form name="form" ng-app="myApp" ng-controller="loginCtrl" novalidate>
  <label>
    Password:

    <input type="password" name="password" ng-model="password" ng-attr-type="{{ showPassword ? 'text':'password'}}" />
    <div ng-click="toggleShowPassword()" ng-class="{'fa fa-eye': showPassword,'fa fa-eye-slash': !showPassword}" style="cursor: pointer;"></div>

  </label>
</form>

You can also try this one

<input type="{{showPassword?'text':'password'}}" />
<input type="checkbox" title="Show Password" ng-model="showPassword" ng-checked="showPassword">

Thank you for your response, I have tried this but I have like to have what I have added in edited answer how can make it out from this.

To round out this excellent answer, here's the Bootstrap info requested: getbootstrap.com/components/#input-groups Use an input-group-addon.

Why do u use: $scope.params = {}; ?

[Derek Soike]

@grep $scope.params is just an object for holding variables. $scope.params.password gets set by angular's ng-model="params.password" in the html. You'd probably have a login or sign up button that triggers some function that would access the variables in $scope.params.

[FiniteLooper]

to be 100% valid HTML, you'll need to add the type="password" as well, but at angular runtime this will be replaced. Just a tip for anyone that has any kind of automatic HTML validation tooling.

HTML <span class="showPassword" ng-click="togglePassword()">{{ typePassword ? 'Hide' : 'Show' }}</span><br> <input type="{{ typePassword ? 'text' : 'password' }}" name="password" placeholder="Password"> In the Angular Controller $scope.togglePassword = function () { $scope.typePassword = !$scope.typePassword; };
