I want to make it empty.

Like this:

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

or like this in jQuery:

 $('#myTextarea').val('');

Where are you

 <textarea id="myTextarea" name="something">This text gets removed</textarea>

For all descending and unbelievers:

If you can use jQuery, and I highly recommend you do this, you just do

 $('#myTextArea').val('');

Otherwise, it is browser dependent. Assuming you have

 var myTextArea = document.getElementById('myTextArea');

In most browsers you

 myTextArea.innerHTML = '';

But in Firefox you do

 myTextArea.innerText = '';

Finding out which browser the user is using remains as an exercise for the reader. If you are not using jQuery, of course;)

Edit : I take it back. It appears that support for .innerHTML on textarea has improved. I tested in Chrome, Firefox and Internet Explorer, they all cleared the text box correctly.

Change 2 . And I just checked if you use .val ('') in jQuery, it just sets the .value property for textarea's. So the value should be good.

Although many correct answers have already been given, the classic approach (read non-DOM) will be like this:

 document.forms['yourform']['yourtextarea'].value = 'yourvalue';

where in HTML your text area is nested somewhere in this form:

 <form name="yourform"> <textarea name="yourtextarea" rows="10" cols="60"></textarea> </form>

And as it happens, it will work with Netscape Navigator 4 and Internet Explorer 3 too. And, no matter, Internet Explorer on mobile devices.

put the text box on the form, name them and just use dom objects, for example:

 <body onload="form1.box.value = 'Welcome!'"> <form name="form1"> <textarea name="box"></textarea> </form> </body>
