Update classes

[dnectom]

function setBrand()
{
    var Brand = document.getElementById("Brand")
    var updateclass = getElementsByClass("Brands")
    updateclass.value = Brand.options[Brand.selectedIndex].text
}
 
function getElementsByClass(cName) {
       var tabReturn = new Array();
      var tabTmp = new Array();
      tabTmp = document.getElementsByTagName("*");
      j=0;
       for (i=0; i<tabTmp.length; i++) {
           if (tabTmp[i].className==cName) {
             tabReturn[j]=tabTmp[i];
         j++;
           }
        }
       return tabReturn;
    }

<tr>
            <td><select id="Brand" name="Brand" onchange="setBrand()">
            <option>Select</option>
            <?php 
                $sql = "SELECT * FROM `go3_brand`";
                $result = &$dbconn->query($sql);
                while ($row = $result->fetch()) {
                        print "<option value=\"$row[id]\">$row[brand]</option>";
                }
            ?>
            </select></td>
            </tr>
            <tr>
            <td><input type="text" class="Brands" value="" /></td>
            </tr>

I've been scowering the web and am unable to find how to update all classes in a document with a certain value which is entered within an input...
Any idea why this doesn't work or links to else where to go
