Trigger Marketo Lightbox on buttonclick - marketo

Question

The code that Marketo provided us with currently launches a lightbox on page load, but we would like the lightbox to be triggered when a button is clicked.
We would very much appreciate being pointed in the correction direction on how to go about achieving this. I have looked though the Marketo Developer documentation, and through stackoverflow questions tagged 'Marketo' but have been unsuccessful finding an example of how to do this.
Here is the code Marketo has provided us with. I have removed unique identifying numbers like Munkin and formId.
<script src="//app-ab02.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_number"></form>
<script>MktoForms2.loadForm("//app-ab02.marketo.com", "number", number, function (form){MktoForms2.lightbox(form).show();});</script>

Answer 1

Try this
Put your form anywhere on the page
<script src="//app-ab02.marketo.com/js/forms2/js/forms2.min.js"></script>
<form id="mktoForm_number"></form>
Then
<script type="text/javascript">
$("#popup-link").click(function(e){
e.preventDefault();
MktoForms2.loadForm("//app-sjh.marketo.com", "mktoForm_ID", "mktoForm_number", function (form){MktoForms2.lightbox(form).show();
// Hide the form and display a thank you message
form.onSuccess(function(form){
formElem = this.formElem[0];
formParent = formElem.parentNode;
formParent.removeChild(formElem);
formParent.innerHTML = '<h3>Thank you!</h3>';
});
});
});
</script>
