title: jquery not working to change inner html?
body: <p>hey people I'm new at jquery and i have been trying to figure this out for like the past couple of hours... what the hell am I doing wrong here? All I want to do is change the innerHTML of a div. </p>
  
  <pre><code>$("left_menu_bar").innerHTML = "You clicked me!";
  </code></pre>
  
  <p>but the div doesn't change at all when I call the function with that code init.</p>
