Returning/passing Java script variable/value to PL/SQL environment

Question

Hi,
Can someone give me a sample code about how to return a Java script variable to PLSQL environment?
for example, I have a javascript function that returns timestamp in milisecond, I then want to write PLSQL code to call this java script function and save its value in a number-typed plsql variable for further calculation, I dont know how the two scripting language communicate.
Thank you very much

This is quite simple.
I assume that you are able to define html form side through pl/sql. Suppose your new pl/sql value is v_time then in the procedure that you write include one more statement
htp.p('<Input type=hidden name="v_time" value="">');
and also in the form invocation,
htp.p('<form name=app method=post action="time_handler" onSubmit="return false;">');
and to the end you must be having a submit
to it attach a onClick function that calls
simply our validate function..
eg htp.p('<Input type=submit value="process"
onClick="validate();">');
Include in the head portion
the following script using htp.p procedure
function validate()
app.v_time.value=<calculated value>;
return app.submit();
Hope this helps.
