title: javascript find an id that contains partial text
body: <p>Environment: Just JavaScript</p>
  
  <p>Is there a way to get an element that contains partial text?</p>
  
  <pre><code>&lt;h1 id="test_123_abc"&gt;hello world&lt;/h1&gt;
  </code></pre>
  
  <p>In this example, can I get the element if all I had was the <code>test_123</code> part?</p>
