values_to_datalayer_step_by_step.html

<script>
// all the marketo from 2.0 javascript has successfully loaded, so we can continue
MktoForms2.whenReady(function (form) {
    // the user has just submitted the form
    form.onSubmit(function(){
        // marketo provides a form object with a nifty method to get the values from the form
        // we'll store those values in a "vals" variable
        var vals = form.vals();
        // now we can push to the dataLayer
        dataLayer.push({
            // we get two types of information from this dataLayer push
            // the first is the fact that a marketo form was submitted
            // in other words: hooray, we got a lead!
            'event': 'marketoFormSubmit',
            // the second type of information is about the lead itself
            // your marketo setup/form will differ; play with the values to get what you need
            // just be super careful about personally identifiable info!!
            'marketoCompany': vals['Company'],
            'marketoLeadSource': vals['LeadSource'],
            'marketoOriginalSource': vals['Original_Source_Detail__c'],
            'marketoCurrentSource': vals['Source_Detail__c']
        });
