How to get the index of forEach loop in integer

Question

I want to get the index of forEach loop in integer, I can get it in terms of string i.e

<c:forEach var="row" items="${result.rows}" varStatus="loop">
    <c:out value="${loop.index}"/>
</c:forEach>

I want to store the value of index in an integer variable, jsp.

Just store it in a variable, it will actually be an integer:

<c:set var="index" value="${loop.index}" />
<c:set var="index" value="${index + 1}" />
<c:out value="${index}"/>

Should produce 1 2 3 and so on.

well, I want to store the index in a variable which can be accessed in javascript within the jsp,i need to store it in string or int, The problem being I don't know how to use jstl tags with javascript. – HighNESS Dec 18 '15 at 20:38
You have to understand that JSP is executed on the serverside. Just write a JavaScript function like you would do in plain HTML: `` ... you can also replace `someVariable` with an EL Expression to output the index: `` which will result in `` for example. – phortx Dec 18 '15 at 23:32
