title: Display current URL in a chrome extension
body: <p>After doing some research, the code that I have come up with is this:</p>
  
  <pre><code>var outUrl;
  // first get the windowid
  chrome.windows.getCurrent(function(window) {
      // then get the current active tab in that window
      chrome.tabs.query({
          active: true,
          windowId: window.id
      }, function (tabs) {
          var tab = tabs[0];
          document.write(tab.url)
      });
  });
  </code></pre>
  
  <p>This is in a javascript file which is called from my popup html file. It does not, however display the URL of the current website, instead it displays nothing.</p>
  
  <p>I have found multiple posts about this on this and other websites but I haven't been able to implement any of the supposed solutions.</p>
  
  <p>Any help would be greatly appreciated.</p>
