Document#getElementById takes the ID of the element to locate.

If you want to use a selector, try Document#querySelector:

const linkButton = document.querySelector('#homenav li:nth-child(2) a');

if(linkButton) {
  linkButton.addEventListener('click', function() {
    alert('Test');
  });
}
<div id="homenav">
  <div class="navbar navbar-default  navbar-fixed-top" role="navigation">
    <div class="container">
      <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar">
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
          <span class="icon-bar"></span>
        </button>
      </div>
      <div id="navbar" class="navbar-collapse collapse">
        <ul class="nav navbar-nav"></ul>
        <ul class="nav navbar-nav navbar-right">
          <li><a href="#">Home</a></li>
          <li><a href="#">Table Ranking</a></li>
          <li><a href="#">Blog</a></li>
        </ul>
      </div>
