Re: dynamically generating user input fields

[Yaragalla Muralidhar]

Actually i have a "List students "  in my action class. but when i
am dynamically genaerating fields in html page how to change the names of
the fields that are dynamically getting generated?   for the first field i
gave students[0].name but for the second field that is dynamically getting
generated how can i change the name of the field like "students[1].name?

As member of your action you can use a Map. The Map-Key is 
the dynamic field name. You need some JS to generate a new input-field in 
the browser. As html-input-name you can use an OGNL expression like 
"map['fieldName']". That way struts can set the keys and values in your 
action's map.

dynamically generating user input fields

[Yaragalla Muralidhar]

Hi i have a jsp page with a button "capture student details". when that
button is pressed it has to display few user input fields on the same page
like "student Name", student id and few other fields . now user enters the
details of the student and when he press the button again the same set of
fields have to appear again in order to capture the 2nd student details.
how to achieve this?
