Question

So I tried this:

var allItems = jQuery();

function additems(items) {
    allItems = allItems.pushStack(items);
}

additems(jQuery("#ul1").find("li").first());
additems(jQuery("#ul2").find("li").first());
additems(jQuery("#ul3").find("li").first());


allItems.each(function() {
    jQuery("ul1").append(this);
});

She doesn’t work in jsFiddle.

What I need is to keep a collection of some <LI> items hopefully in a jQuery object. And i’d like it to use a function passing in a jQuery object. I also need to add to the collection inside a function like what I have above so it can be done at different times in the code.

i know i can get around it by something like:

function additems(items){
    items.each(function(){ allItems.pushStack(this);});
}

or by just sending them as a list of HTML <LI> Elements, but I’d rather do it something like the above and I haven’t found a clean and efficient way of doing this.

Thanks!

PS: I’d rather not need a plugin.

UPDATE

let me explain more. I have one function that does something and it has an <ul> element from which i can pull out the <li> elements.

I then want to send these elements to another function to keep them for later.

function doSomething1()
{
    //Do something

    var ulElement = getFromSomewhere();
    additems(jQuery(ulElement).find("li"));

    // do something else
    return;
}

function additems(items)
{
    MyObject.allItems.pushStack(items)
}

the jsFiddle was Simplified compared to my code.

ANSWER

Upon adding Quincy’s answer to my fiddle in a way that didn’t remove all my code i got:

var allItems = jQuery();

function additems(items) {
    allItems = allItems.add(items);
}

additems(jQuery("#ul1").find("li").first());
additems(jQuery("#ul2").find("li").first());
additems(jQuery("#ul3").find("li").first());


allItems.each(function() {
    jQuery("ol").append(this);
});

And this works.

Firstly, if you want to select by id, you have to add a '#' in the selector.
And you can add jquery collections using the add() method

var allItems = 


jQuery("#ul1").find("li").first()
.add(jQuery("#ul2").find("li").first())
.add(jQuery("#ul3").find("li").first());


allItems.each(function() {
    jQuery("ol").append($(this));
});
