How can I pass text from a div (#test) to a textarea (#message) that is in an iframe window on click.

You need to get the DOM object of the iframe document, select the desired element in it and set its value.

var text = this.innerHTML;
var iframe = document.getElementById('iframe1');
var textarea = iframe.document.getElementById('textarea1');
textarea.value += text;

could be so

<div id="test" onclick="document.getElementById('iframe1').document.getElementById('textarea1').value +=this.innerHTML">Передано в textarea iframe</div>
