SharePoint - Select List

I have used the following JavaScript to set the default item in a "List form Field"   The script is working and the correct item in the combo box is selected  but the event has not fired to reload the list box. below.  If I select an item manually (i,e. with a mouse) it works fine.  What have I missed.

var elm = document.getElementById("idAttachmentsTable");
          if (elm == null || elm.rows.length == 0)
          document.getElementById("idAttachmentsRow").style.display='none';
         
         
         
  _spBodyOnLoadFunctionNames.push("fillDefaultValues");



function fillDefaultValues()
{
var opt=document.getElementById("ctl00_m_g_f12af616_6ab4_4c5c_a59b_146a2e9b17ae_ff61_ctl00_ctl00_SelectGroup");

var opts = opt.options;
var l = opts.length;
opts.selectedIndex = 4;

      
      }

Hi,
as long as I do not have all the HTML code, its a little bit of blind coding - but the following should work.
<script type="text/javascript" src="http://dev.dse.local/sites/ee/SiteAssets/jquery-1.8.2.min.js"></script>
<script type="text/javascript">
function SetPreselect() {
var optionToSelectText = "YOURTEXTOFTHEOPTIONTOBESELECTED";
jQuery("#idAttachmentsRow").hide();
jQuery("#ctl00_m_g_f12af616_6ab4_4c5c_a59b_146a2e9b17ae_ff61_ctl00_ctl00_SelectGroup").val(optionToSelectText);
}
_spBodyOnLoadFunctionNames.push("SetPreselect");
</script>

Open in new window


Please adjust the text of the variable optionToSelectText to fit the option text of your choice e.g. "Sh Sq Rooms".

The question is not very clear. Can you please explain a bit more. Is this the entire code?

Also please use the code block to write the code. That shows us a bit of clear code.
