Form Embed - get 'form pre-fill' to work on non-marketo landing pages

Has this been fixed or is there a way around it?

Cross browser compatibility is a reach of a user case, IMHO.  Most people tend to prefer a single browser, but in any case it's like saying "What if you're on your phone or on your computer?"

I embed my forms on Marketo LPs and use the following code in my forms embed to pre-pop. If you iFramed in a Marketo LP with the form you should be able to utilize this code to pre-pop still. I suppose you could also pass over the {{lead.Lead ID}} in a URL parameter and, on the form, have a hidden field for Lead ID which would pre-pop. I've never tried it before but it seems doable.

form.vals({"PostalCode":"{{lead.Postal Code}}",

                 "Phone":"{{lead.Phone Number}}",

                 "FirstName":"{{lead.First Name}}",

                 "LastName":"{{lead.Last Name}}",

                 "Company":"{{company.Company Name}}",

                 "Email":"{{lead.Email Address}}",

                 "City":"{{lead.City}}",

                 "Title":"{{lead.Job Title}}",  

                 "State":"{{lead.State}}",

                 "Address":"{{lead.Address}}"});

Can't you just set cookies with the info you'd want pre-filled?

Any updates on this?
