How to clear the portal form fields while clicking on Back button in browser?

Question

Hi All,
I have a portal form, which calls another form. When I types in a value and presses submit, it goes to the new
form with the information on it. When I click on the back button in the browser, it will show the last value user
has entered. I want to clear these values, when I click on the back button in the browser.
Any help is greatly appreciated.
Thanks & regards,
Nevin

Lets assume that the name of the field, whose value you want to clear off,
is SEARCH_TEXT :-
Steps :-
1> Edit the form and goto the Additional PL/SQL Section
2> Add the following code to the "...after displaying the page" area
declare
l_form_name varchar2(200);
l_sess_id integer;
begin
l_form_name := p_session.get_module().get_name();
l_sess_id := p_session.get_id();
htp.p('<script>
var fieldName = "'||l_form_name||'.DEFAULT.SEARCH_TEXT.01";
var formObj = document.WWVM'||l_sess_id||';
for (var i=0; i < formObj.length; i++){
if (formObj.elements.name == fieldName){
formObj.elements[i].value = "";
break;
</script>
end;
