title: jQuery to select href with a forward slash in it
body: <p>I have a link
  <code>&lt;a href="foo/bar"&gt;example&lt;/a&gt;</code></p>
  
  <p>and I'm trying to use jQuery to select it via</p>
  
  <p><code>$("a[href=foo/bar]")</code></p>
  
  <p>but I run into the following error:</p>
  
  <p><code>Error: Syntax error, unrecognized expression: a[href=foo/bar]</code></p>
  
  <p>Without the <code>/</code> this method works fine, however the <code>/</code> is there because of the routing in my Backbone app.  I'd prefer to avoid the extra markup of setting id's as this method works for everything else.  Is there any way to select this <code>&lt;a&gt;</code> using the href attribute with this slash?</p>
