i have this code

<tr>
                                <td  width="300">
                                        <label for="tag">Model</label>
                                </td>
                                        <td>
                                                <td width="10">:</td>
                                        </td>
                                <td>
                                        <td>
                                                <td width="450" align="left">
                                                <input type="text" id="tags1" name="model">
                                                </td>
                                        </td>
                                </td>
                        </tr>

if i type inside textfield "E" i want inside another cell show like:

<tr>
       <td><label><h6>this version <input type.......show E>
                  <br>87.5-108.0</br></h6></label>
        </td>
</tr>

but if type "J" will show:

<tr>
       <td><label><h6>this version <input type......show J>
                  <br>87.5-107.9</br></h6></label>
        </td>
</tr>

what's code that can make it works after press enter?
