Web development jsp java MVC A detailed question about form_html/css_WEB-ITnose
This is an order display and there is a button to cancel the order
This link button should be placed in the form
But because my order is transferred from the database
I don’t know how many orders there are.
So the form should also be dynamically generated
You can write it like this, using only one form and one order
If you put the form in the loop, it will be useless
It looks like this
ReserveList There are already multiple order objects stored in it
for(int i=0;i< ReserveList.size();i++) {out.println("<form name='form7'action='/g0103/servlet/servBDReserveCancel?rnum="+ReserveList.get(0).getReserveNum()+"' method='post'><a href='javascript:form"+(i+7)+".submit()' class='btn_buy' >取消</a></form>");}What should I do? ? ?
I have been thinking about it for a long time but there is no way. . . Help

Reply to discussion (solution)
You should To ask this question in the JavaEE module, go to http://bbs.csdn.net/forums/J2EE.
In addition, you have said that it is MVC, and the view and model are separated:
The HTML content of the page should be written in JSP.
Just pass the ReserveList object in the servlet and display it using EL or JSTL.
As for the problem you encountered, you can use Ajax instead of directly using Form to submit the form;
Like a general list page, each row (item) has a delete button. Click the delete button,
will pass the item ID to the server through Ajax for deletion, and then provide feedback and so on.
