Display the array length using JSTL

[Romeo Ranjan]

Hi all,

I am looping through an array and here is my code

<TD ALIGN="center"><c:forEach var="rowcount" items="${data}" varStatus="status">
  <B> Count ${status.count}  </B></c:forEach></TD> 

The problem is the output i get

Count 1
Count 2
Count 3

It loops through the array and prints each time. What I want is I want to assign
the count to a variable and display the count like this.

Count 3

How do I go about doing this?

I don't really get what you want to achieve here? The count value IS already in a variable you can print out (status.count), and it comes out in the form you want. Or do you only want to print it if count has a specific value (like 3 here)? You can check that using

<c:if test="${status.count eq 3}">
  <!-- do something -->
</c:if>

Thank you very much for the reply. Sorry for not being clear. I want only the final count value alone. Everytime it loops through it prints Count 1 Count 2 and so on.
But what I want is the total count alone, only the value 3. How can I achieve this? Hope I am clear

Instead of outputting the count value, just assign it to a variable. Then output that variable after the loop is finished.

Hi Paul

Would be possible for you to show an example so that I could learn?

Thanks

Which one are you having trouble with? Assigning something to a variable, or displaying the value of a variable?

Edit: No, never mind. I see you already know how to display the value of a variable. So it must be assigning something to a variable which is your question. You would use the

<c:set>

element for that.

<td ><c:forEach var="rowcount" items="${data}" varStatus="status">  
  <c:set value="${status.count}"/></c:forEach>value</td> 

Is it something like this?

I found out. Thanks a lot for helping me learn.
