How I can prevent the user form Enter same data when into Custoemrs form?

Hi
I have PHP form application used to by Sales reps to Enter information about customers but I want to prevent Sales reps from entering same information because of web form behavior after they want to add new customer ?
is their away in using Jquery to clear the form for new entry ??

You can do something like this and it will reset every form element to its original value:

$('#myform').each (function(){
  this.reset();
});

thank for help

Typically the autocomplete on form fields appears based on the name of the form field. So, if you give the form field a unique name, perhaps by making use of time/date or a unique hash, that can be a viable solution too.
