title: How to prevent execution of javascript from a browser's address bar?
body: <p>If I go to <a href="http://www.bloganything.net/731/cool-javascript-tricks-for-internet-browsers" rel="nofollow noreferrer">this</a> page and then delete the url from my browser's address bar, and then enter  </p>
  
  <pre><code>javascript:document.getElementById('rsidebar').value='dsf';
  </code></pre>
  
  <p>The whole part refreshes. How can I prevent a page from refreshing when executing javascript from the address bar?</p>
  
  <p>Also, are there any other techniques to manipulate a page without having access to the page source like the above method?</p>
