Class IteratorStatus
java.lang.Object
  org.apache.struts2.views.jsp.IteratorStatus

The iterator tag can export an IteratorStatus object so that one can get information about the status of the iteration, such as:

• index: current iteration index, starts on 0 and increments in one on every iteration
• count: iterations so far, starts on 1. count is always index + 1
• first: true if index == 0
• even: true if (index + 1) % 2 == 0
• last: true if current iteration is the last iteration
• odd: true if (index + 1) % 2 == 1

Example

   <s:iterator status="status" value='%{0, 1}'>
      Index: <s:property value="%{#status.index}" /> <br />
      Count: <s:property value="%{#status.count}" /> <br />  
   </s:iterator>

will print

      Index: 0
      Count: 1
      Index: 1
      Count: 2
