Question

I am having problems with an AJAX function I am working on.

The function is supposed to insert some information into a DB. The problem comes when I put the whole AJAX code inside a loop, because it crashes. Here is an example of a code which is similar to what I am doing:

function funcionDePrueba() {
    var url = 'aaajax.py'
    var x = 3
    for (i = 0; i < x; i++) {
        xmlhttp = GetXmlHttpObject();
        if (!xmlhttp) {
            alert("Browser does not support HTTP Request");
            return;
        }
        var xml = xmlhttp;
        xmlhttp.onreadystatechange = function() {
            if (xml.readyState == 4) {
                alert(claveProyecto);
            }
        };
        xmlhttp.open("GET", url, true);
        xmlhttp.send(null);

        return true;
    }
}

Is it possible to put the whole AJAX code inside a for loop?

Answer 1

Yes, it is possible.

But; In the provided snippet you have a return statement inside your for-loop. This will make the loop have one go and then return from the function. If you’d like it do to more than one iteration, remove the statement: return true.
