The completion event was not triggered during the AJAX request

I am having an issue with a function that I have created to make an ajax call. Despite using the .done method, it does not seem to be firing as expected. Upon checking my console for errors, I came across the following message:

https://i.sstatic.net/CbYBR.png

function getIncidentInfo() {
    $.ajax({
        type: "GET",
        url: "../../page_components/statsboard/stats.php",
        data: $(this).serialize(),
        dataType: "json",
    }).done(function(response) {
        incidentAr = response;
        for (var i in incidentAr) {
            var zaNorth = parseInt(incidentAr[i].zaNorth);
            ......
        }
    }).fail(function(xhr, status, error) {
        console.log("Status: " + status + " Error: " + error);
        console.log(xhr);
    });
}

I reached out to a friend and asked them to test the same piece of code, and they reported that it worked perfectly for them.

Answer №1

When attempting to access stats.php, an XDebug error is being thrown, causing it to return HTML detailing the error message instead of the expected JSON output. To troubleshoot this issue, try loading the stats.php page in a browser or reviewing your PHP logs for more information on the specific error.

Answer №2

  1. Try using .always(response) instead of .done(response). Some APIs might return non-200 status codes along with a response body to explain the error.
  2. Inspect response.responseJSON, response.responseText, and response.responseXML. In some cases, you may need to do something like
    response.responseJSON = eval(respaonse.responseText)
    .

It appears that the responseText is in HTML format. Based on the 200 status code (not 404 or 500), it's likely you're receiving a generic server error displaying content from an unintended route.
