Angular Character Limit
This is my directive to limit the number of characters you can enter in a text field. It assumes you are using Bootstrap, and appends the warning class to your
control-group at 10 characters left, and
error at 0.
You need to include the
igCharLimit.js file before your app, but after angular.
This directive creates a new html attribute called char-limit. On your
<input /> or
<textarea></textarea> you put
char-limit="x", where x is the number of characters you wish to limit the field to.
// Load the directive<script src="jquery.js"></script> <script src="angular.js"></script> <script src="igCharLimit.js"></script> <script src="ngApp.js"></script>
// In your controller // Include the module in your app var ngMyApp = angular.module('myApp', ['igCharLimit']);
// In your markup <textarea ng-model="message" char-limit="10"></textarea>
- Angularjs (Tested against 1.0.1 and later*)
- Bootstrap (This directive assumes you are using it, and assigns the warning, and error classes to your elemenets control-group div, but does not need Bootstrap to function.)
- Remove dependency on jQuery
- Remove assumption on Bootstrap
