I am pretty sure this code did run a week ago, have their been changes to the API it seem it never enter loop because e.options.length undefined?

function getPortIndex(){
var e = parent.document.getElementById("out_portsel");
alert(parent.out_portsel.length);
for (var i=0;i<parent.out_portsel.length;i++){
alert("WTF");
if (e.options[i].value=="FW1884 Control"){ctrlportindex=i; alert(ctrlportindex); break;}
else{alert("nonevalid port");}
}
}

Changed to e.length now it work, but i am pretty sure i used length of the form last week.

Here again, I think this code could be factored to be easier to read and verify.

let E = (x)=>parent.document.getElementById(x);

function getPortIndex(){
let e = E("out_portsel");
return e.options.findIndex( (opt)=>opt.value=="FW1884 Control" );
}

I started to write a findfirst() function using .forEach() but after glancing at online refs I noticed .findIndex() which does all the looping business. There is a difference here in that my version uses the length of
e.options[] instead of parent.out_portsel[] but that part doesn't really
make sense to me so I'm not sure if it's important. If they're not the same,
it might be worth investigating that so functions like this can be short
and sweet.

Can't say i like the Javascript syntax though what is the (opt)=> about and why is it necessary?
Why not just e.options.findIndex( (opt.value=="FW1884 Control" );

That's a good question. I believe it's part of a batch of features added to IIRC Ecma 5 (and more in 6) to support functional programming.
A lot of the array methods are really nice for replacing loops of various kinds. But the price is you have to do it "functionally" which means
passing in a function. It doesn't have to use the array syntax.

You could also write it like:
e.options.findIndex( function(opt){ return opt.value=="FW1884 Control"; } );

But the code in middle (the *predicate* here, because it returns a boolean)
has to be wrapped up in a function. I like the arrow syntax because it
feels very lightweight and direct, but not everyone likes it. That's a valid reaction. It does look weird.

This is a change I had to learn (twice) in my programming life. First in college,
then again years later when I picked it back up as a hobby. The downside is
you never stop hunting bugs, but the bugs get weirder and more interesting. I've been scratching my head for weeks over a 200 line program in PostScript that does (tries to do) parsing of regular expressions using parser combinators.
It's only 200 lines, but I can't find the bug! But I don't envy what the task would be like if the program were 2000 or 20000 lines.

It's a stupid question but your answer it's an even worse pile of pure crap:
as usual, your incompetence is second only to your arrogance.

Don't worry about Julio the Plonker, he just gibbers non-stop
foul-mouthed nonsense into the group. Killfiling him is the
recommended solution.

You're right. I overreacted. I thought I'd made some progress with Julio in our last exchange. I apologize for increasing the foul-mouthedness.
