How to initialize array (in Javascript) with c:forEach tag?

Question

I'm a bit confused. I'd like to know if there's a way to initialize an Array in javascript inside a c:forEach tag.

var Array = [];
   <c:forEach var="item" items="${data}">
       // something like -> Array[i] = ${item.user.fullName}
   </c:forEach>

${data} is passed to the .tag page through this command at the beginning:

<jsp:directive.attribute name="data" required="true" rtexprvalue="true" type="java.util.Collection" />

I know that something is working cause I see few fullName sometimes.

I don't know exactly if this is possible. I'm on this project and I'm trying to solve this.

Thanks.

Why don't you just generate the array of full names on the java side and then pass that? That's usually a lot better than doing it in the javascript — Sacha, Jun 07 '18 at 13:54

I solved it! This is the code:

var Array = [];
      <c:forEach var="item" items="${data}" varStatus="yourStatus">
        Array[${yourStatus.index}] = '${item.user.fullName}';
      </c:forEach>

I found a perfect solution for this case. Thanks.
