Adjusting the height of a textarea with javascript

I am trying to reset the contents and height of an auto resizing textarea element.

My attempts so far include:

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

As well as:

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

Unfortunately, neither of these methods have been successful for me.

UPDATE :

I am using autosize.js with the following setup:

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

Answer №1

To clear the automatically added style attribute after resizing, you can utilize the setAttribute method:

document.getElementById('reset').onclick = function(){
    var textBox = document.getElementById('target');
  
    textBox.setAttribute('style','');
    textBox.value = "";
}
<textarea id="target" rows="1" cols="10"></textarea>
<br>
<button id="reset">Reset Text Box</button>

Answer №2

Consider resetting the formatting:

Adjust the height of the textarea element to "20px":
document.getElementById("textarea").style.height = "20px";

Answer №3

Here is a handy JQuery snippet that I always use to clear the input field when closing a modal in my project:

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