Below you can find a set of demonstrative Forms 2.0 web form examples.

Hide Form After Successful Submission

This example does not take the visitor to the follow up page or reload the current page.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function(form) {
    // Add an onSuccess handler
    form.onSuccess(function(values, followUpUrl) {
        // Get the form's jQuery element and hide it
        form.getFormElem().hide();
        // Return false to prevent the submission handler from taking the lead to the follow up url
        return false;
    });
});

Take Visitor to User-Defined URL

This example takes the visitor to a URL determined by JavaScript after successful submission, instead of to the configured thank you page.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function(form) {
    //Add an onSuccess handler
    form.onSuccess(function(values, followUpUrl) {
        // Take the lead to a different page on successful submit, ignoring the form's configured followUpUrl
        location.href = "https://google.com/?q=marketo+forms+v2+examples";
        // Return false to prevent the submission handler continuing with its own processing
        return false;
    });
});

Set Form Field Values

This example sets form fields.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function(form) {
    // Set the value of the Phone and Country fields
    form.vals({ "Phone":"555-555-1234", "Country":"USA"});
});

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);
        });
    }
};

Set Values on Hidden Fields on the Form

This example sets values on hidden fields.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function (form) {
    // Set values for the hidden fields, "userIsAwesome" and "enrollDate"
    // Note that these fields were configured in the form editor as hidden fields already
    form.vals({"userIsAwesome":"true", "enrollDate":"2014-01-01"});
});

This example shows the form in a lightbox style dialog if the url contains a parameter lightboxForm=true.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function (form) {
    if (location.href.indexOf("lightboxForm=true") != -1) {
        MktoForms2.lightbox(form).show();
    }
});

Show Custom Error Message

This example shows a custom error message on submit based on custom business logic.

MktoForms2.loadForm("//app-ab00.marketo.com", "785-UHP-775", 1057, function (form) {
    //listen for the validate event
    form.onValidate(function() {
        // Get the values
        var vals = form.vals();
        //Check your condition
        if (vals.Country == "USA" && vals.vehicleSize != "Massive") {
            // Prevent form submission
            form.submittable(false);
            // Show error message, pointed at VehicleSize element
            var vehicleSizeElem = form.getFormElem().find("#vehicleSize");
            form.showErrorMessage("All Americans must have a massive vehicle", vehicleSizeElem);
        }
        else {
            // Enable submission for those who met the criteria
            form.submittable(true);
        }
  });
});
