Frames

[Antonie C Malan Snr]

Dear All,

The top frame contains a form with many select elements. They are used
to do database searches. As the selects are based on data in the
database which is loaded onLoad (the top page is a JSP) I do not want to
load the page in the top frame again after the initial load.

The page in the bottom frame is also a JSP and reads a the search
results from a bean when it loads.

So, what I want to do is send the form contents from the top page to the
servlet, the servlet then gets it via a few other classes from the
database and it is loaded into the bean. The bottom frame then needs to
refresh and it will get the search data from the bean.

I've tried parent.mainFrame.location.reload() and various other things
like parent.mainFrame.open("results.jsp", "mainFrame", "") etc. No luck.

Any idea what the best way is? I am better with Java and databases than
with JavaScript.

Thanks,

Chris

Pure HTML. Give the form in the top frame a TARGET attribute that names
the bottom frame and an ACTION attribute the refers to the JSP being
displayed in the bottom frame and when the form is submitted the
response will be sent to the (named) bottom frame, effectively
refreshing its contents. You just have to make sure that the JSP for the
bottom frame is set up to load the submitted information into the bean
and that doing so updates the bean's state with the search results via
the database.

than with JavaScript.

Whenever something can be achieved with HTML and server-side scripting
alone it is best to question the need to involve client-side scripting
at all.

Richard.

Hi Richard,

Thanks for that. I'm now going to try it. What will happen to the
contents of the top frame that I want to preserve, if at all possible?
