Adding javascript variable to html textarea

Question

I know this must be doable, does anyone know how and if you can do it?

Answer 1

or you can do it like this:

var myVar = 'sup fresh our turn baby!';
var myTextArea = document.getElementById('myArea');
myTextArea.innerHTML += myVar;

Answer 2

Something like this should work:

var textArea = document.getElementById("mytextarea"); // assuming there is a textarea with id = mytextarea
var textToAppend = document.createTextNode("Hello, World!");
textArea.appendChild(textToAppend);

EDIT: or, as Walkney suggested, the last two lines can be replaced with:

textArea.value += "Hello, World!";

Answer 3

function appendText(str) {
var obj=document.getElementById("myTextArea")
var txt=document.createTextNode("append this text")
obj.appendChild(txt)
}

Answer 4

The guys said:

document.getElementById('whatever').value += someJavascriptString;
