Check internet connection before save a form

I am developing an application that will be used on tablets using 4G.
The forms have more than 200 fields.
I need to check that the tablet has internet access before saving the form.
I have verified that once I try to save a form, if there is no internet access, scriptcase returns an error and the entered data is lost without option to retry.
Can somebody help me?


try it with AJAX. Examples are in the samples for forms. Or here’s another simple example
