I have a textarea (auto resizing) and I want to clear all of its contents including its height.

So far I've tried:

document.getElementById('textarea').value = '';

And :

document.getElementById('textarea').attribute('rows','1');

But both doesn't work.

EDIT :

I use autosize.js with this :

<textarea id="post" rows="1" title="Write something..." name="posttxt" placeholder="Write something..." role="textbox" autoplete="off"></textarea>

• Can you show the HTML that defines your textarea? – user5684647 Commented Mar 18, 2016 at 15:01

You could use setAttribute to reset style attribute added automatically during the resize :

document.getElementById('reset').onclick = function(){
    var textarea = document.getElementById('target');
  
    textarea.setAttribute('style','');
    textarea.value = "";
}

<textarea id="target" rows="1" cols="10"></textarea>
<br>
<button id="reset">Reset</button>

Try resetting the style:

document.getElementById("textarea").style.height = "20px";

Just a JQuery version, that I'm using when I close a modal on my project

$("#jobURL").attr("style", "").val("")
