title: How to include an HTML file with jQuery?
body: <p>I want to make my code separate so I decided to divide each <code>div</code> to html files. Each HTML file has some jQuery click events. I have 2 files <code>index.html</code> and <code>menu.html</code>.</p>
  
  <p>Problem is that I have to include the jQuery library in both files to make it work.</p>
  
  <p>Is there any way that I can include library one time and have it work on both files? I tried to include the library in the  index page only, but then the menu click doesn't work. </p>
  
  <p>I included the <code>menu.html</code> file through an iframe.</p>
  
  <pre><code>&lt;iframe src="left-menu.html"&gt;&lt;/iframe&gt;
  </code></pre>
