Multiple forms on same page

[Ajay Patil <ap...@vertex.co.in>]

Dear Jing,

In the scenario that you describe (Multiple forms on same HTML page) -

The browser will send only the data inputted on the form whose submit
button is clicked. The data inputted in other forms will not be
sent to the server, and so there is no way the server can send it
back in the next page.

I think the only way to solve this problem is to control the HTML
so that only one form is editable at a time.

Thus, the detail form becomes editable only when you click on "Edit"
detail button. (and when the detail form is editable, the master
form is not editable).

You can also show/hide forms to achieve a similar effect. Though this
is possible in Javascript, I like to do it in JSP on server-side, using
a state property in the form class to indicate what state the form
is currently in.

Let me know what you think,
Ajay

Hi, Ajay,

I think what you proposed is a very reasonable way to construct a
page with multiple html forms.

When the page is in the master mode, all of the detail form elements
are disabled. When the page is transferred into the detail mode,
the form elements in the master form are disabled and only the
corresponding detail form elements are enabled.

It looks very useful in use cases when end users need to know
information on the mater form to enter data into one of detail forms.

Thanks.

Jing

The submit will only submit the one form...
