Jay's snippet is for the specific case where the first field that is subject to Visibility Rules -- regardless of what field that is -- is the one you want to move to the bottom of the form, just above the Submit button.
Jay bundled it with part of the form embed code, which might be confusing you. It actually stands alone like so, and you don't need to alter anything you've already got, just add this after the standard Forms 2.0 embed code (also shortened the snippet, as long as we're going for the lightest-weight approach):
<script>
MktoForms2.whenReady(function(form){
var formEl = form.getFormElem()[0],
firstRowWithVisRule = formEl.querySelector(".mktoPlaceholder").parentNode,
submitButtonRow = formEl.querySelector(".mktoButtonRow");
if (firstRowWithVisRule) {
formEl.insertBefore(firstRowWithVisRule,submitButtonRow);
}
});
</script>
However (as Jay cautions) this code won't work anymore if you change your form structure (order of fields and/or number of fields w/VRs) because you aren't telling it anything about the real form field names, just the form field positions as of this point in time.
For code that continues to work even if you change how the form looks/behaves, you'd include the 2 FormsPlus scripts, then call reorderFields like this:
<script>
MktoForms2.whenReady(function(form){
var fieldOrder = ["PermissionToEmail"];
reorderFields(fieldOrder);
});
</script>
Where PermissionToEmail is of course the name of the field you're targeting. As you can see, the site-specific code here is even shorter than the standalone code snippet above, but you do have to grab copies of the FormPlus JS for this to work. If that's proving too difficult you can use the standalone/single-use way. Note also that you don't have to include the FormsPlus scripts as external <script src> tags and host the files anywhere. If it's easier, you can just copy-paste the code + copyright and paste into 2 local <script> blocks. Put those <script>s above the <script> that calls reorderFields is all.
