I want to clear a value of a span inside a div without deleteing other contents only the contents of a span.

ex:
body:

<div id=content>

  <span>one</span>



  <input type=text />

  <input type=text />



  <span>two</span>

  <span>three</span>



  <select>

        <option selected=selected value=></option>

        <option value=Monday>Monday</option>

        <option value=Tuesday>Tuesday</option>

        <option value=Wednesday>Wednesday</option>

        <option value=Thursday>Thursday</option>

        <option value=Friday>Friday</option>

        <option value=Saturday>Saturday</option>

        <option value=Sunday>Sunday</option>

  </select>

</div>

script:

<script type=text/javascript>

function restSel() {

   document.getElementById(#content span).innerHTML=;

};

</script>

Clear all the spans or the content of all the spans.
