jquery get one object in an array as an array

Question

With jQuery I can do

$('#some_id').find('div').first()

or

$('#some_id').find('div').last()

and get an answer like

[<div>something</div>]

If I do

$('#some_id').find('div')[3]

I get answer like

<div>something</div>

How do I specify an index in array and get an array just with that object?

I would love to do something like

$('#some_id').find('div').somefunc(3)

and get

[<div>something</div>]

I know there is slice(), but I feel like there is some simpler function that I have over looked in my hours of searching.

I know there is :nth-child() but again, it feels like there is some other function that I can call the way I call first() or last().

I am trying to chain some functions together to have one line that does what I need.

If there is not other ways, then I guess that is fine. I just wanted to make sure.

Thanks!

You can use .eq():

$('#some_id').find('div').eq(3) // This will return the fourth div inside #some_id

Since .eq() is 0-based index, if you want to get the third div you need to use:

$('#some_id').find('div').eq(2)

Thanks! I was searching for hours and then 2 minutes after I posted this, I found it. But since your answer is correct, you get the check. :-)

You can also use .get(index)

$($('#some_id').find('div').get(3)); // jQuery obj

or

[$('#some_id').find('div').get(3)]; // Array

The .get() method grants access to the DOM nodes underlying each jQuery object. If the value of index is out of bounds — less than the negative number of elements or equal to or greater than the number of elements — it returns undefined.

Thanks for taking the time to answer. To my understanding get() gets the element, not an array with the element.
