How Can I Create a Truly Auto-Resizing Textarea That Shrinks and Grows with Content?

Creating a Textarea with Auto-Resize

In a previous discussion, a method for creating an auto-resizing textarea was presented. However, a limitation remained: the textarea failed to shrink upon content deletion. The crucial issue lies in obtaining the correct height of the textarea's content.

Complete Solution

The following code provides a comprehensive solution that addresses the limitations encountered with the previous method:

$("textarea").each(function () {
  this.style.height = this.scrollHeight + "px";
  this.style.overflowY = "hidden";
}).on("input", function () {
  this.style.height = "auto";
  this.style.height = this.scrollHeight + "px";
});

Advantages:

  • Works on key input
  • Supports pasted text (right-click & ctrl v)
  • Handles cut text (right-click & ctrl x)
  • Accommodates pre-loaded text
  • Applies to all textareas (multiline textboxes) site-wide
  • Compatible with Firefox, Chrome, IE, Edge, iOS Safari, and Android Browser
  • Strict JavaScript mode compliant

Implementation:

  1. Include the jQuery library in your master script file.
  2. Copy the JavaScript code snippet into the master script file.
  3. The self-adjusting textareas are now available for use on your website.

With this enhanced code, textareas can now effortlessly auto-resize, providing a user-friendly and consistent experience across various platforms and browsers.
