  <browser>
  function getMaxOption(selectEl){
     var opts = selectEl.options; // get the options
     var values = []; // blank array
     for (var i=0; i<opts.length; i++){
        var num = parseInt(opts[i].value); // get the integer value of string
        if ("" + num != "NaN")  // check if it is a number and add to array
            values[values.length] = num;
     }
     return values.sort(function(a,b){return a-b;}).pop(); // sort it ascending numerically and return last value.
  }
  </browser>
  
  _alert(getMaxOption(_select("myDropDown"))); // Should alert the max number in this dropdown.

  Hi Nayaran,
  
  We have an internal application LMS in this application we are having 2 pages those are Leave Application and Leave Modification Request. After successful requesting a Leave one number will be generated (Leave Request No) and this will be available in the Leave Modification Request page under Leave Request No dropdown. Here I want to select Leave Request No which was requested earlier means latest Leave Request No from Leave Request No dropdown list.
  
  Note: we don’t know the latest Leave Request No until unless selecting the dropdown list in the Leave Modification Request page.

  Srini,
  
  Did you try the code in my previous reply? I think if you do

  _setSelected(_select("leaveReqNo"),  ""+getMaxOption(_select("leaveReqNo")));
  

  it should work. Change "leaveReqNo" to the identifier of your select box.
  
  Regards,
  Narayan

  Hi Narayan,
  
  i have tried with the following but i am getting null value. i am not getting dropdown list max value.
  
  function GetMaxValueInDropDown($selectEl)
  {
  var opts = $selectEl.options; // get the options
  var $values = []; // blank array
  
  for (var $i=0; $i<$opts.length; $i++)
  {
  var $num = parseInt($opts[$i].value); // get the integer value of string
  
  if ("" + $num != "NaN") // check if it is a number and add to array
  {
  $values[$values.length] = $num;
  }
  }
  
  return values.sort(function($a, $b){return $a - $b;}).pop(); // sort it ascending numerically
  and return last value.
  
  _alert($values);
  
  _setGlobal("LeaveRequestDDMaxValue", $values[0]);
  }

  Srini,
  
  Are the options in the dropdown visible as numbers when you look at them? If yes, there is a small change needed in the function.
  
  Btw, you have to use the code as is. No need for modifications. Remember to use the browser tags for that function.
  
  

  <browser>
  function getMaxOption(selectEl){
     var opts = selectEl.options; // get the options
     var values = []; // blank array
     for (var i=0; i<opts.length; i++){
        var num = parseInt(opts[i].text); // get the integer value of displayed string
        if ("" + num != "NaN")  // check if it is a number and add to array
            values[values.length] = num;
     }
     return values.sort(function(a,b){return a-b;}).pop(); // sort it ascending numerically and return last value.
  }
  </browser>
  
  // This will set the select box with the option with maximum displayed value.
  _setSelected(_select("leaveReqNo"),  ""+getMaxOption(_select("leaveReqNo")));
