Conditions in the sequence of commands

Question

Trying to figure out a way to insert a condition in Jquery sequence of commands. Basically my point is I can save the code length.

Example:

var first=true;

if(first){
    ap.nextAll("div").first()....
}else{
    ap.nextAll("div").last()....
}

and whether it can do something like this:

ap.nextAll("div").(first?first():last())....

This is the only example I know that it could be solve : last, but it just as an example.

Thanks Pesulap

yes you can use bracket notation along with ternary operator

ap.nextAll("div")[first? 'first' : 'last']()....

This blew my mind. I was about to post a contradictory answer. – Joost Jan 23 '14 at 08:13
'first' and 'last' is function so it might be without quote? – Bhojendra Rauniyar Jan 23 '14 at 08:13
No, `first` and `last` are properties of jQuery objects that name functions. When using brackets, you put them in quotes to get the properties. – Barmar Jan 23 '14 at 08:14
@C-link no... we are using a bracket notation and is passing object keys which are referencing functions... so the keys are strings – Arun P Johny Jan 23 '14 at 08:14
@Arun P Johny - Nice, and it would function in the condition still concatenate? ex: [first? "first". "hide", "last". "show"] () – Pesulap Jan 23 '14 at 08:22
@Pesulap no `ap.nextAll("div")[first? 'first' : 'last']()[first? 'hide' : 'show']()` may be? – Arun P Johny Jan 23 '14 at 08:26
@Arun P Johny - Ok, thanks a lot, I thought it was impossible. And I do not think this is a duplicate topic. – Pesulap Jan 23 '14 at 08:30
