You can install this package either with npm or with bower.


npm install angular-trustpass --save

Then add trTrustpass as a dependency for your app:

angular.module('demoApp', ['trTrustpass']);


bower install angular-trustpass --save

Add <script> and <link> to your page:

<link rel="stylesheet" href="bower_modules/angular-trustpass/dist/tr-trustpass.css">
<script src="bower_modules/angular-trustpass/dist/tr-trustpass.js"></script>

Then add trTrustpass as a dependency for your app:

angular.module('demoApp', ['trTrustpass']);



<input type="password" tr-trustpass>

With options

<input type="password" tr-trustpass="{special: false}" ng-minlength="9">

Using with Bootstrap classes:

<form name="demo">
  <div class="form-group" ng-class="{'has-error': demoForm.password.$invalid && demoForm.password.$dirty,
                                     'has-success': !demoForm.password.$invalid && demoForm.password.$dirty}">
    <label for="password">Password</label>
    <input id="password"
           tr-trustpass="{maximum: true, special: false, messageGuide: 'Make sure your password meets these requirements:'}"
  <button type="submit" ng-disabled="demo.password.$invalid" class="btn btn-primary">Sign in</button>

Password model will have $invalid set true and $error.trustpass set true when any of the tests fail. You can then style your form or input with Angular validation classes.


Pass a json object to tr-trustpass like this: tr-trustpass="{maximum: true, special: false}"
