function updateStatus() {
url: ‘pcdsEmpRecords.php’,
success: function(response) {
// update div id Results

Set the ‘disabled’ attribute to true or false:
// Disable #pcds
$(‘#pcds’).attr(‘disabled’, true);
// Enable #pcds
$(‘#pcds’).attr(‘disabled’, false);
Add or remove the ‘disabled’ attribute:
// Disable #pcds
$(“#pcds”).attr(‘disabled’, ‘disabled’);
// Enable #x

There are two ways to check or uncheck a checkbox or radio button.
Set the ‘checked’ attribute to true or false.
// Check #pcds
$(‘#pcds’).attr(‘checked’, true);
// Uncheck #pcds
$(‘#pcds’).attr(‘checked’, false);
Add or remove the ‘checked’ attribute:
// Check #pcds
$(“#pcds”).attr(‘checked’, ‘checked’);
// Uncheck #pcds

Select elements typically have two values that you want to access. First there’s the value to be sent to the server, which is easy:
// => 1
The second is the text value of the select. For example, using the following select box:
If you wanted to get the string “Mr” if the first option was selected (instead of just “1″), you would do that in the following way:
$(“#mpcdsselect option:selected”).text();
// => “Mr”

Dollar Sign is nothing but it's an alias for JQuery. Take a look at below jQuery code




Over here $ sign can be replaced with "jQuery " keyword.
