JQuery exception when select option with whitespaces
<p>I have a problem with select option in html select element via JQuery. Next code demonstrate my problem:</p>

<pre><code>$('select[name="location"] option[value=' + 'mercedes mercedes' + ']').attr('selected', true);
</code></pre>

<p>And i have simple html code for select with option value - "mercedes mercedes". When I run my script - i got exception:</p>

<blockquote>
  <p>"Error: Syntax error, unrecognized expression: [value=mercedes mercedes]
  throw new Error( "Syntax error, unrecognized expression: " + msg );"</p>
</blockquote>

<p>When I delete whitespace - all is ok. Maybe anyone know - how to fix it?</p>
