Splunk jquery not executing in order

Question

I am working on simple XML dashboard in Splunk to compute and display infra requirements for new Splunk environment. Below is an excerpt from the code which I am not able to get right:

    $(document).on('click', '#submitDemand', function(e) {
    e.preventDefault();
    //hostname, ip, storage, ram, os, component, cores
    indexers = indexernum($('[name="form_totalgb"]').val());
    console.log(indexers);
    shs = shnum($('[name="form_totalgb"]').val());
    console.log(shs);
    spinfraTableSearch = new SearchManager({

});

As you know, this function is called when submit is clicked and I have included console.log() to debug the code, please excuse the quick/dirty nature. For variables indexers and shs, values 3 and 2 produces below output:

shs1 completed
start shssearch[2]
and shs1/shssearch[2] keeps on repeating

I am not able to figure out why while executing indexer loop, start idxsearch[1] is not executed even though idx[0], idx[1] and idx[2] are registered.

Similarly in shs block, start shssearch[1] should be called not start shssearch[2]. Further the shs for loop should not execute if i=2 but here it becomes as infinite loop.

Any help in this matter is appreciated. I am stuck in this since weeks and have rewritten this at least 4 times.

Best Regards, Nikhil

Edit: Shorter version:

     var i = 1;
for (i = 1; i < indexers; i++) {
    console.log('in for register idx[' + (i - 1) + ']');
    idxsearch[i - 1].on('search:done', function() {
        console.log('idx' + (i - 1) + ' completed');
        console.log('start idxsearch[' + i + ']');
        spinfraTableSearch.startSearch();
        idxsearch[i].startSearch();
    });
}

Output: start idxsearch[0] idx1 completed start idxsearch[2] Issue: idx0 completed, start idxsearch[1] and idx1 completed are missing. Those piece of code should be executed

Code2:

    var i = 1;
for (i = 1; i < shs; i++) {
    console.log('register shs[' + (i - 1) + ']');
    shssearch[i - 1].on('search:done', function() {
        console.log('shs' + (i - 1) + ' completed');
        console.log('start shssearch[' + i + ']');
        spinfraTableSearch.startSearch();
        shssearch[i].startSearch();
    });

Issue: similar problem shs0 completed and start shssearch[1] are missing. And this is in infinite loop where as value of i as 2 should restrict it.

This is too much code, you should be able to reproduce your problem with a lot less code. Until you can do that, you should do your own debugging — Ruan Mendes, Dec 28 '17 at 17:41
well, I agree but this is to provide a holistic view. The problem pieces are `for loop` for `indexers` and `shs`. Main issue that I cant understand is when I get good values when registering the hooks why does it skips while executing them? — nikhil14, Dec 28 '17 at 17:46
Sorry nikhil, this is more code than I'm willing to look at, for free at least :) You have to make it easy on those willing to help, do you own debugging, break down the problem, you may solve it yourself, SO is not a tool to keep you from debugging your code, it's for after you've debugged it and can't still get it to work. First step is remove chunks of code until the bug is gone... — Ruan Mendes, Dec 28 '17 at 17:53
I understand, half of above code is setting the pretext for those two loops. I have edited the post to explain my earlier comment and highlighting prob areas. But still keeping the full code for someone who is willing to go through it and will be helpful for someone who is developing in Splunk. Please try to give it 10 mins of your time. Thanks — nikhil14, Dec 28 '17 at 18:09

wow, thanks James it does seems like the same issue, let me attempt to solve using the examples given. However, what would be the reason for correct values when registering hooks? — nikhil14, Dec 28 '17 at 18:29
Not really sure which part of your code is the registering of hooks, but I would guess that you are not using `i` within the inner, anonymous functions of that part of your code (at least in any important way, like beyond logging it). — James, Dec 28 '17 at 18:38
Thanks James, it was JavaScript closure bug and I was not aware about the concept. Now code works as it should. How should I mark your comment as answer? — nikhil14, Dec 29 '17 at 09:15
