How do I do this JavaScript using jQuery?

Question

In JavaScript I can use the following code both ways, i.e:

var a = document.getElementById("emp").value;
document.getElementById("emp").value = a;

So I can basically retrieve a value as well as assign a value using ...().value

In jQuery, what is the equivalent to the above, i.e retrieve and assign?

get value:

var empVal = $("#emp").val();

assign value:

$("#emp").val("this is a new value");

var a = $('#emp').val();
$('#emp').val(a);

The val accessor works like the value property, except that it's extended to work nicely even with input fields like selects and checkboxes. See its documentation.

Better cache the element than the value:

var $a = $("#emp");
$a.val($a.val());
