Input:

Var = $XXX (' # ID). Val ()

---------------------------------------------------------------------------------

The checkbox.


var xxx = [ ];
$('input[name=MyName]:checked).each(function(index, element) {
xxx.push($(element).val());
//Or XXX. Push ($(this). Val ());
});

Note: there is no ID based here. If your checkbox element is a child of a container (assuming the container's id is con_id), you can choose:

= = = = = =


$('#con_id input[name=MyName]:checked')
 or 
$('input[name=MyName]:checked', '#con_id')

----------------------------------------------------------------------------------

Radio:

Var = $XXX (' input [name = MyName] : checked "). The val ();

= = = = = =

Note: there is no ID based. To limit the specified ID, see the case of the checkbox above

----------------------------------------------------------------------------------

Select:

Var XXX = $("#ID option:selected").val();

= = = = = =

Two points to note:

1. Select "seleted" instead of "checked."

2. The default of select is "single", if it is multiple, I have not tried. I think we can handle each().
