How view of table can be controlled on a Button

[Dinesh Remje]

there are various fields in table like name, gender, addr, college name, college url, college addr, project details etc.
Now i want that only few details should be displayed on page like name, addr, gender, city, coll addr. Above the table i have provided a button whose value is MORE DETAILS.
After clicking the button the table should get expanded to show all the details i mean all the fields.
Right now i have created two jsp pages where 1st JSP page has selected fields and the 2nd JSP page has all the fields which i have achieved through the code shown below

<form name="form1" method="post" action="regist1.jsp">
      <input type="submit" name="Submit" value="More Details">
  </form>

So i want to ask is there any other method through which i can achieve the above functionality by maintaining only one JSP page and not the two JSP page of same contents.

Of course. Use <c:if> to decide whether to include the extra details or not.

Thanks for the reply i got it, but how can i check that the button is clicked in <c:if> loop

[Bear Bibeault]

Have the page controller set a scoped variable in the request that determines whether the summary or detail view is to be shown. The conditional can check that variable.

i have done the following changes in my code but its not working

 <c:if test="${pageContext.request.method=='POST'}">
<c:if test="${param.Submit==NULL}">

I have checked here that the button is not clicked.
But its not working

[Dinesh Remje]

do i need to decalre that param.Submit variable in begining

[Dinesh Remje]
