Auto Grow Textarea Vertically To Fit Content - textAdjust

textAdjust is a small yet customizable jQuery auto grow plugin for textarea element that automatically adjusts the height of your textarea to fit the content while typing.

How to use it:

1. Create a normal textarea element and specify the min/max number of rows using the HTML5 data attributes:

<textarea id="example"
          rows="4" 
          data-min-rows="2" 
          data-max-rows="5">
</textarea>

2. Download the plugin and import the JavaScript jquery.textAdjust.js after jQuery (slim build).

<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" 
        integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" 
        crossorigin="anonymous">
</script>
<script src="jquery.textAdjust.js"></script>

3. Call the function textAdjust on the textarea element and the plugin will do the rest.

$(function(){

  $('textarea').textAdjust()

});

4. You can also specify the min/max number of rows to shrink/expand in the JavaScript.

$('textarea').textAdjust({
  min: 2,
  max: 10
})

5. Sometimes you might need to destroy the plugin.

$('textarea').textAdjust('destroy')

6. Available event handlers.

$('textarea').textAdjust()
  .on('textAdjust.grow', function(event, oldRows, newRows){
    // on grow
  })
  .on('textAdjust.shrink', function(event, oldRows, newRows){
    // on shrink
  })
  .on('textAdjust.nochange', function(event, oldRows, newRows){
    // when no change
  })
  .on('textAdjust.init', function(event){
    // on init
  })
  .on('textAdjust.destroy', function(event){
    // on destroy
  });
