I know this question has been asked before, but I tried to apply the answers with no results.

I'm trying to do multiple requests on the same domain with a for loop but it's working for the entire record of my array.

Here is the code I use:

function showDesc(str) {
    var prod = document.getElementsByName("prod_item[]");
    var xhr = [], i;
    for (i = 0; i < prod.length; i++) {
        var txtHint = 'txtHint10' + i;  
        (function(i) {
            var xhr = new XMLHttpRequest();
            var url = "getDesc.php?q=" + str;

            xhr.onreadystatechange = function () {
                if (xhr.readyState == 4 && xhr.status == 200) {
                    document.getElementById(txtHint).innerHTML = xhr.responseText;
                }
            };
            xhr.open("GET", url, false);
            xhr.send();
        })(i);
    }
}

PHP

<select name="prod_item[]" id="prod_item.1" onchange="showDesc(this.options[this.selectedIndex].value)"></select>
<div id="txtHint100"></div>

and then I will use dynamic table for the prod_item field and div_id.

Is there any mistake in my code?

function showDesc(str) this str is sent every time with your xhr request. so what is in the str you need to work on the variable – Haque Jun 10 '18 at 17:04
so, whats should I do with the value from the php file? – Lodeweyk Andri Jun 10 '18 at 17:09
Hi Haque,I need to pass the selected item in html, and use it as criteria on my sqlscript in the getDesc.php. – Lodeweyk Andri Jun 10 '18 at 17:14
what value you're getting using this `this.options[this.selectedIndex].value` ? – Haque Jun 10 '18 at 17:54
