Question

I would like to replicate jquery object selection, for example

When i select multiple objects with

var test = $(".someclass");

I get the object with all selected objects with that class.

Now how could i keep adding objects in that war, something like test.push($(".somediv"));

Also i saw .add( jQuery object ) but it gives me error Cannot call method 'add' of null
when i try to add object to an empty variable

Also how can i create jquery variable with no values and then add them later?

You can use $() to create an empty jQuery object and then you can use .add() to add more items to it via a selector:

var items = $().add(".someClass");
items = items.add(".someDiv");

When using .add(), just remember that it returns a NEW jQuery objects that have the new elements added in. It does not modify the original jQuery object. It’s easy to forget that and do:

items.add(".someDiv");

and wonder why nothing is added to items (this has bit me several times).
