I have an ul with 9 li elements. I want to load some information to these li elements through ajax in asynch mode.

It's so simple, isn't it?

I just created a for(i = 1; i<=9; i++) loop, and called the $.post.

Fail: i will be always 10, because the for loop running more faster, then the $.post. So let's search the $.post in loop on net.

I found three solutions. Two are here, and one is here.

All of it has the same effect: does not works asynchronously. Every time it load the first, then second, then third etc... Sometimes the order is changing, but every request wait while the previous finish.

I am using WIN 10 64bit, Apache 2.4 64 bit, php 5.6 64bit. Already tried on debian box, effect is the same.

In my php file, there is a sleep(1) and an echo 'a'.

My first attempt:

$('.chartContainer').each(function(index,obj) {
    var cnt = index + 1;
    $.post(getBaseUrl() + 'ajax.php', {dateTime: $('#chart_' + cnt).data('time'), action: 'getChartByDateTime'}, function (reponse) {
        $(obj).html(reponse);
    });
});

My second attempt:

for (var i = 1; i <= 9; i++) {
    (function (i) {
        var $obj = $('#chart_' + i);
        $.post(getBaseUrl() + 'ajax.php', {dateTime: $('#chart_' + i).data('time'), action: 'getChartByDateTime'}, function (reponse) {
            $($obj).html(reponse);
        });
    })(i);
}

My third attempt:

function loadResponse(i) {
    var $obj = $('#chart_' + i);
    $.post(getBaseUrl() + 'ajax.php', {dateTime: $('#chart_' + i).data('time'), action: 'getChartByDateTime'}, function (reponse) {
        $($obj).html(reponse);
    });
}

$(function () {
    for (i = 1; i<=9; i++) {
        loadResponse(i);
    }
});

Expected result:

Every 9 li loaded in 1 second in the same time.

Can somebody lead me to the right solution?

EDIT

Maybe I was not clear. In the production, the script will run for approx. 3 seconds. If I send one request to get all the data back, then it will take 9*3 = 27 seconds while the response arrives. This is why I want to send 9 request, and get back all the data in 3 seconds. I think this is why we use threads.

What I want is to get all the data for all li in the "same" time. Not one by one, or get all in one request.

EDIT 2

Ok guys, shame on me, I think I mislead all of you. There is a session start in my php script.

If I remove everything, and then just echo something and die after sleep. In this case 5 request is responding in 1 sec, other 4 is later. But I think that is a new thred.
