Laravel, Get Values from checkbox in jquery

I have an issue that i am trying to get the values from checkbox to jquery but am getting only one value and all the checkbox have that value, here is my code:

<form  method="post">
              @foreach($services as $service) 
            <tr>
              <td><input type="checkbox" onchange="check()" name="check_box" id="check_box" value=></td>
              <td></td>
            </tr>
            @endforeach 
<form>

Service names are multiple and user can select multiple options and i want to get multiple options in jquery, here is my code for jquery:

  <script type="text/javascript">
  function check(){
    var testing = document.getElementById('check_box').value;
    console.log(testing);

  }
</script>

It is only giving the value of 1st loop.

Can anyone help me?
