Angular-charlimit

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.

Use

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.

For example…

// 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', ['igTypahead']);

// In your markup
<textarea ng-model="message" char-limit="10"></textarea>

Requirements

• Angularjs (Tested against 1.0.1 and later*)
• jQuery
• 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.)

Todo

• Remove dependency on jQuery
• Remove assumption on Bootstrap
