javascript thread: How do I show a "wait" message after submitting a form and waiting for the response
Let us get this scenario Clear,
You have a JSP Page which creates HTML output. This HTML output has two
frames. One of these frames (hiddenFrame) has a JavaScript function
(doSomething()).
Now when you submit the page to a Servlet, you write out <Script language
JavaScript>doSomething();</Script>
And you expects doSomeThing to execute.
Now I am assuming that your display.html was submitted to invoke your
servlet. In that case the results of the submission will by default come
to
the FRAMESET where display.html was sitting. In that case you can still
access the Java Script Fn in Hidden.html by the following notation.
document.parent.hiddenFrame.doSomething();
When you use hidden Frames to continuously hold JavaScript functions and
variables, It is a good practice to use the TARGET property of Form submit
to pinpoint the FRAMESET to which submission should happen.
thank you
