title: Use multiple OR with one AND
body: <p>I want to use multiple OR with one AND operator, but in this example I get error even when I fill <code>#ads-estate-age</code>.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$('a').click(function() {
    if ($('#ads-subsubcategory').val() == 92 || $('#ads-subsubcategory').val() == 103 || $('#ads-subsubcategory').val() == 97 || $('#ads-subsubcategory').val() == 100 &amp;&amp; $('#ads-estate-age').val().length &lt;= 0) {
      alert('its empty');
    } else {
      alert('ok');
    }
  });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;input type="text" id="ads-subsubcategory" value="92" /&gt;
  &lt;input type="text" id="ads-estate-age" /&gt;
  
  &lt;a&gt;check&lt;/a&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I tried to add parentheses but still not working:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$('a').click(function() {
    if (($('#ads-subsubcategory').val() == 92) || ($('#ads-subsubcategory').val() == 103) || ($('#ads-subsubcategory').val() == 97) || ($('#ads-subsubcategory').val() == 100) &amp;&amp; $('#ads-estate-age').val().length &lt;= 0) {
      alert('its empty');
    } else {
      alert('ok');
    }
  });</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;input type="text" id="ads-subsubcategory" value="92" /&gt;
  &lt;input type="text" id="ads-estate-age" /&gt;
  
  &lt;a&gt;check&lt;/a&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>What I have missed?</p>
