Read Form Field Values on Form Submit

This example reads form fields on form submit.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function(form) {
    // Add an onSubmit handler
    form.onSubmit(function(){
        // Get the form field values
        var vals = form.vals();
        // You may wish to call other function calls here, for example to fire google analytics tracking or the like
        // callSomeFunction(vals);
        // We'll just alert them to show the principle
        alert("Submitted values: " + JSON.stringify(vals));
    });
});

Form Submit on Non-Form Click Event

This example submits a form based on a click event on some other element or event that is not part of the form.

// Load the form normally
MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057);

// Find the button element that you want to attach the event to
var btn = document.getElementById("MyAlternativeSubmitButtonId");
btn.onclick = function() {
    // When the button is clicked, get the form object and submit it
    MktoForms2.whenReady(function (form) {
        form.submit();
    });
};

Prevent a User From Submitting a Form

For the purpose of this example, you must click the click counter button at least three times before the submit button on the form will function.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function (form) {
    // Check if the form is submittable
    if (form.submittable()) {
        // Set it to be non submittable
        form.submittable(false);
    }
});

var clickCount = 0;
// Wire up the click counter button
var clickCounterBtn = document.getElementById("ClickCounter");
clickCounterBtn.onclick = function() {
    clickCount++;
    // Update the buttons's text
    clickCounterBtn.innerHTML = "Click Counter Button ("+clickCount+")";

    if (clickCount >= 3) {
        // Get the form and set it to be submittable
        MktoForms2.whenReady(function (form) {
            form.submittable(true);
        });
    }
};
