marketo_submit_values.js

MktoForms2.loadForm("//app-sjst.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));
    });
});
