Question

Following up on my question from the other day, I’ve run into another thing that now I’ve spent too many hours banging my head against.

Mostly, I’m having trouble getting the SUCCESS form to submit. I tried this as well:

jQuery form submit

Here’s the code in a semi-functional fiddle:

http://jsfiddle.net/ZcgqV/

Essentially what happens is this:

1. I bind a method to the form’s submission via onSubmit (rather than click)
2. On submit, it calls a remote server via jQuery .ajax() call
3. If the response is “PENDING”, retry every 1s, nine times
4. On failure, don’t submit the form
5. On success, submit the form

No matter what I try, I can’t get the form to either submit when I want it to without going into a loop, or not submit immediately while it tries the remote server.

Here’s the code directly in case you dislike fiddles:

var retries = 0;
var success = false;
var token = "toki wartooth is not a bumblebee";

$(document).ready(function() {
    // Attach the action to the form
    $('#tehForm').attr('onSubmit', 'onsubmit_action(event)');
});

function async(fn) {
    setTimeout(fn, 1000);
}

function pollServer() {
    $.ajax({
        type: "POST",
        cache: "false",
        url: "/remoteCall",
        dataType: "json",
        data: {
            ref_token: token
        }
    }).done(function(data, code, jqXHR) {

        switch (data.status) {
        case "SUCCESS":
            alert("Success");
            success = true;

            // --> HERE IS WHERE I WANT THE FORM TO SUBMIT <--

            break;

        case "PENDING":
            if (retries < 9) {
                retries += 1;
                async(function() {
                    pollServer();
                });
            } else {
                alert("Failed after 9 tries");
            }
            break;

        case "ERROR":
            alert("Error");
            break;

        default:
            alert("Some kind of horrible error occurred");
            break;
        }

    }).fail(function(jqXHR, textStatus) {
        var statusCode = jqXHR.status;
        alert("Request failed: " + statusCode + " " + textStatus);
    });

}

function onsubmit_action(event) {
        pollServer();
        if (success === false) {
            // RETURN FALSE DIDN'T WORK, SO I FOUND THIS
            event.preventDefault();
        }
}​

EDIT:

Again, the real problem here is that I stop submission of the form. On SUCCESS, I want the form to submit. Currently if I use .submit() in SUCCESS, the AJAX is called again, starting the process over. What I want is the ACTION of the FORM to fire on SUCCESS only.

Trying to use as much of the original code as possible; here is a solution:

Post form with post back
http://jsfiddle.net/tpm7v/4/

Post form via Ajax
http://jsfiddle.net/tpm7v/5/

    var retries = 0,
    token = "toki wartooth is not a bumblebee",
    sendRequest,
    handelResponse,
    postFormToServer,
    $theForm = $('#tehForm');

$(document).ready(function() {
    // Attach the action to the form
    $theForm.bind('submit', onsubmit_action);
});

sendRequest = function() {
    $.ajax({
        type: "POST",
        cache: "false",
        url: "/remoteCall",
        dataType: "json",
        data: {
            ref_token: token
        },
        success: handelResponse
    });
};

postFormToServer = function() {
    $.ajax({
        type: "POST",
        cache: "false",
        url: "/remoteCallToTakFormData",
        dataType: "json",
        data: $form.serialize(),
        success: function() {
            alert('success!');
        }
    });
};

handelResponse = function(data, code, jqXHR) {
    switch (data.status) {
        case "SUCCESS":
            postFormToServer();
            break;

        case "PENDING":
            if (retries < 9) {
                retries += 1;
                setTimeout(sendRequest , 1000);
            } else {
                alert("Failed after 9 tries");
            }
            break;

        case "ERROR":
            alert("Error");
            break;

        default:
            alert("Some kind of horrible error occurred");
            break;
        }
};

function onsubmit_action(evt) {
    evt.preventDefault();
    sendRequest();
}

Keep in mind I am going off the code your provided. You should be able to port this to work with your actual implementation. You may also want to try something like https://github.com/webadvanced/takeCommand to help clean up all the Ajax calls.
