title: Object doesn't support property or method 'addEventListener'
body: <p>I am receiving an error on IE 8-7 saying that Object doesn't support property or method 'addEventListener' when I used the code below. Does anyone know how I can make the code below compatible with IE8-7? thanks</p>
  
  <pre><code> document.getElementById('clear').addEventListener('click', function () {
    ["A1","A2","A3","A4","A5","A6", "A1_flip", 
  
    ].forEach(function(id) {
      document.getElementById(id).checked = false;
    });
    return false;
  }) 
  </code></pre>
