Reset to default 8

You are not directly accessing the elements value. The left hand side of your expression is a getter which evaluates to a literal. So the expression is parable to something like 5 = 10, which obviously cant work

$('#id').val() = $.cookie("name");

val() is overloaded, and by giving it an argument you can reassign

$('#id').val($.cookie("name"));

try to use 

$('#id').val($.cookie("name"));

You are using the getter version of val() when you call it with no arguments.

Use $('#id').val($.cookie("name")); instead.

$('#id').val($.cookie("name"));
