Populate a textarea using jquery?

Okay, not sure why this easy jquery is not working for me.

I have a textarea field (Text Box to fill) and a button (EvilButton). When the EvilButton is clicked I wanted it to populate the textarea field.

$(document).ready(function(){

var stupidField = $('textarea[title=Text Box to fill]');

var headerOP1 ='<div><b>So stupid</b></div>';

var headerOP2 ='<div><b>I know</b></div>';

$(stupidField).val(headerOP1);

$("#EvilButton").click(function(){

alert('hi');

$(stupidField).val(headerOP2);

});

});

Everything about this works except the headerOP2/"I know" does not get populated upon button click.

"So stupid" first appears when you open page, the alert works but $(stupidField).val(headerOP2); is not working, I've even tried using $(stupidField).val(headerOP1); which clearly works earlier but doesn't seem to work with the button click. *sigh*.

Update:

Updated...var stupidField = $('textarea[title="Text Box to fill"]');

still not working :(

Update 2:

Okay, so I added a alert($(stupidField).val()); after $(stupidField).val(headerOP2); and it's returning the right result...but it's not showing up in the textarea. Maybe a sharepoint thing?

    Your title query has spaces in it...try:

    var stupidField = $('textarea[title="Text Box to fill"]');

    try this...

    <!DOCTYPE html>

    <html>

    <head>

    <title>Javascript :: PopulateToTextArea </title>

    <script src="http:// code.jquery.com/ jquery-2.1.0.min.js" type="text/javascript"></script>

    <script type="text/javascript">

    $(function() {

    var field = $('textarea[title="Text Box to fill"]');

    var header1 = '<div><b>So stupid</b></div>';

    var header2 = '<div><b>I know</b></div>';

    field.text(header1);

    $('#evilButton').click(function(e) {

    e.preventDefault();

    alert('hi');

    field.text(header2);

    });

    });

    </script>

    </head>

    <body>

    <form>

    <textarea cols="50" rows="10" title="Text Box to fill"></textarea>

    <button id="evilButton">Evil Button</button>

    </form>

    </body>

    </html>
