AngularJS directive for auto-grow / auto-resize of textarea elements on typing.
- Works in all cases: expands on line breaks and word breaks.
- Great Performance: minimal DOM manipulation and no watchers.
- Allows limitation of auto-growing so a scrollbar will appear after X lines of content.
npm install angularjs-autogrow --save
Include angular-autogrow.min.js file in <head> section of the HTML:
<script type="text/javascript" src="angularjs-autogrow.min.js"></script>Include angularjs-autogrow dependency in your angular module:
var app = angular.module("app", ["angularjs-autogrow"]);It's also recommended to add those two CSS properties to make things stable:
textarea {
resize: none;
box-sizing: content-box;
}Add the directive to the textarea element:
<textarea autogrow></textarea>You can limit the auto-growing of the textarea element by using max-lines attribute:
<textarea autogrow max-lines="3"></textarea>You can set the initial line number using rows attribute:
<textarea autogrow rows="1"></textarea>You can define which CSS properties have to be watched in order to trigger the auto-growing:
<textarea autogrow="font-family,font-size"></textarea>
