This might help you: Run Javascript in Chrome Extension -> Basic?

copied here for quick reference:

According to chrome extension documentation,

Inline JavaScript will not be executed. This restriction bans both inline <script> blocks and inline event handlers (e.g. <button onclick="...">).

Read: http://developer.chrome.com/extensions/contentSecurityPolicy.html#JSExecution

Use in popup.js as

document.addEventListener('DOMContentLoaded', function () {
      document.querySelector('button').addEventListener('click', main);      
});
function main() {
    var source = document.getElementById('source').value;
    document.getElementById("result").innerHTML = source;
}
