Question

I have JSP string array like

String[] valueArray = new String[valueList.size()];
valueArray = valueList.toArray(valueArray);

I want to use this in Javascript using JSTL

    var array = new Array();
 <c:forEach items="${valueArray}" var="item">
 array.push("${item}");
 </c:forEach>

somehow this does not work. it does not populated any values. Please help.

Answer 1

If the first set of codes are scriptlets in your jsp file, you should change your second set of codes as something like:

var array = new Array();
 <% for(int i=0; i<valueArray.length; i++){ %>
 array.push("<%= valueArray[i] %>");
 <% } %>

Or if they were a part of a java file (may be a servlet or an action class), you should add a line:

session.setAttribute("valueArray", valueArray);

This will add your valueArray in your session, ready to be retrieved on your jsp.
