title: How to check an entire string if it contains a specific word using jQuery?
body: <p>I need help on checking a certain word if it contains in a string that is being assigned into my input textbox.
  For example below, If there's a string value assigned to this textbox</p>
  
  <pre><code>&lt;input type="text" id="StartLocation" name="StartLocation" value="1 AAC, MT SECTION, RAF SCAMPTON, LINCOLN, LN1 2ST, UNITED KINGDOM" &gt;
  </code></pre>
  
  <p>I want to check if it contains the word "<strong>UNITED KINGDOM</strong>" and if does not, it should return false.
  I tried something like this below but it keeps returning true because the alert message is always 'It contains United Kingdom' even though I already
  change the value. </p>
  
  <pre><code>if ($("input#StartLocation:contains('UNITED KINGDOM')")) {
    alert('It contains United Kingdom');
  } else {
    alert('It does not contains United Kingdom');
  }
  </code></pre>
  
  <p>How do I fix this? Thanks...</p>
