Question

I wonder if anyone can advise? I have a JSP which contains two forms, both of which are mapped to the same servlet on the server.

Everything seems fine although when I submit one form, a necessary piece of data entered on the other form is not being submitted at the same time.

The first form is used to add or delete the address of an RSS feed. As there may be several addresses on the page, a table is used to store them. Each cell of the table contains a form like this for deletion:

<form action = "<c:url value = '/deleteRSSFeed?rssFeedURL=${rssFeedURL}' />" method = "post">                           
<input type = "image" src = "${imageFileURL}myApp_rightArrow.png" />                            
<input name = "writeWordcloud" type = "hidden" value = "true" />
</form>

And there is another form for adding a feed.

The situation is that upon submission of either of these forms, a wordcloud must be redrawn on the page. But the wordcloud’s settings are contained in the other form.

As it not possible for me to merge the forms, can anyone tell me if I can share data betwen forms in HTML? Or better yet, is it possible to submit one form, and have this action submit the second form?

At this point, it is not practical for me to have the forms served by different servlets.

Thanks

By using Javascript (or better, jQuery), you can have hidden fields in one form get the other form’s fields values before submitting.
