Please provide what server technology you are using; clarify what you mean by "session" (Traditional PHP $_SESSION, etc); Finally, post what you have tried so far.Doug Neiner– Doug Neiner2010-01-05 17:44:03 +00:00Commented Jan 5, 2010 at 17:44

its a java session. I just populated the select as under. #foreach( $emp in $allEmp) <option value= #end on select of one employee I would have to populate the values related to that employee on the form (such as sex, dob, city etc.,). I am trying to do this using jquery. Any help would be great.Aanu– Aanu2010-01-05 17:48:45 +00:00Commented Jan 5, 2010 at 17:48

You could store employee information into a javascript object:
var employees = [
{ id: '1', sex: 'm', city: 'Paris' },
{ id: '2', sex: 'f', city: 'London' },
... etc fill this in a foreach loop
];
Next you bind to the change event of the select box:
$(function()
{
$('select#id_of_the_employees_select').change(function(e) {
// Get the current selected employee id
var selectedEmployeeId = $(this).val();
// find the corresponding employee in the list
var emps = $.grep(employees, function(n, i) {
return n.id == selectedEmployeeId;
});
if (emps.length > 0) {
var employee = emps[0];
// fill the form elements with employee data:
$('#employee_sex').val(employee.sex);
$('#employee_city').val(employee.city);
}
});
});
