Question

I’m trying to access the id of the element nextElementSibling in the array presented in the picture below:

items[3].item.nextElementSibling.attr('id'))

This query does not work. Whereas I can access the id of the item element like so:

items[3].item.attr('id'))

Can someone explain me why the second works, whereas the first does not work!?
Thanks for your help!

Answer 1

.attr() is a jQuery function, but you are not testing it on a jQuery object ($()). Just get its id directly with normal JavaScipt:

items[3].item.nextElementSibling.id

Or wrap it in $() to access jQuery functions:

$(items[3].item.nextElementSibling).attr('id')
