Submit after populating field from a type ahead search...

[asevie]

I'm converting a search feature that currently uses two successive dropdown fields to do the search. The search is initiated when the user selects the option from the dropdown. The resultant (it's always 1 record) is then displayed in detail with a + sign next to it so that the user can add the record he just searched for.

 

I've replaced it with a single dropdown and type-ahead field that uses javascript. The type ahead replaces the second drop down. I didn't want users have to select amongst hundreds of records in a drop down, by forcing them to start typing the second drop down, I can narrow the results to the exact item the user is looking for.

 

My problem is that I'm not sure how to get the type ahead result to initiate the search on the user select. I initiate it like this in the old version...

 

            <table>

                <tr>

                    <td width="130px" valign="top"><form name="nav"><select name="platform" id="platform" onChange="document.location.href=document.nav.platform.options[document.nav.platform.selectedIndex].value">

                        <option>Platform</option>

                        <?

                            $result = mysql_query("SELECT * FROM Platform");

                            while($row = mysql_fetch_array($result)) {

                        ?>

                        <option value="?ptfm_ctrl=1&ptfm_id=<?=$row['id_platform']?>" <? if ($_GET['ptfm_id']==$row['id_platform']) { ?>selected="selected"<? } ?>><?=$row['platform']?></option>

                        <? } ?>

                    </select></form></td>                   

                    <?

                        if (isset($_GET["ptfm_ctrl"])) {

                    ?>

                        <tr>

                  </table>

 

 

 

The new solution generates the type ahead result like this...

 

  <div>

      <form>

        <div>

            Start typing the name of the product, select the correct title when it appears:

            <br />

            <input type="text" size="30" value="" id="inputString" onkeyup="lookup(this.value);" onblur="fill();" />

        </div>

       

        <div class="suggestionsBox" id="suggestions" style="display: none;">

            <img src="upArrow.png" style="position: relative; top: -12px; left: 30px;" alt="upArrow" />

            <div class="suggestionList" id="autoSuggestionsList">

               

            </div>

        </div>

      </form>

  </div>

 

This populates the field but I'd like to submit it on the populate. How can I initiate the search using the second method?
