Autosubmit Script Gives Double Records As A Back Button Is Used

[peterhanse]

good morning, someone an idea?

 

 

I have a Submission Form with an auto submit script ( java, see below).

The problem  is that if users press their back button , the form once more is added .

The form used parameter so i can reset the parameters, This holding the second time  a blank field. I am now looking for a script that gives a cancel button if that field is empty and  overruled the autosubmit script .

 

P.S. I can not requierd the field because he come in a loop.

 

Regards Peter

  document.getElementById("caspioform").style.display = 'none';

  setTimeout('document.forms["caspioform"].submit()',1000); }
