I have a form that must execute a javascript function on submit, the function then posts data to my php send mail file and the mail is sent. But it only works in fire fox. T
I always include the js files in the head of the html document and them in the action just call the javascript function. Something like this:
action="javascript:checkout()"
You try this?
Don't forget include the script reference in the html head.
I don't know cause of that works in firefox. Regards.
