I found this http://jsfiddle.net/uES22/ and modified to http://jsbin.com/uZuzIlET/1/edit

function getSelectedText() {
    if (window.getSelection) {
        return window.getSelection().toString();
    } else if (document.selection) {
        return document.selection.createRange().text;
    }
    return '';
}

var b = document.getElementsByTagName('body')[0],
    o = document.getElementById('result');

b.onmouseup = function(e){
    var selText = getSelectedText(),
        targetElem = e.target.tagName.toLowerCase();
    if (selText && targetElem == 'textarea') {
        o.textContent =  selText ;
    }
};

Open in new window

<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
  <div>You can not select me</div>
  <textarea>Select me and it works. Beer is good food.</textarea><br>
  <div id="result"></div>
</body>
</html>

Open in new window

I think that solution may have started here http://www.codetoad.com/javascript_get_selected_text.asp
