I have a .jsp page in which I used on click JavaScript function for further validation and other processing stuff. Now I've created an array in jsp scriptlets and how do I pass into this JavaScript function that gets called when submit button is hit? I tried something like this:

var jsArray = <%=lineArray%>;

But that didn't work out.
In fact the function wasn't getting called after I the put above scriptlet. So how do I copy this java array into a JavaScript array?

Google something like AJAX and Client-Server principle. –  reg4in 14 hours ago

Try something like this:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

var jsArray = [ 
  <c:forEach var="item" items="${lineArray}">
   <c:out value="${item}"/>,
  </c:forEach>
];

This will generate javascript array variable jsArray and put the Java lineArray values into it. If that's what you need to do.

What is prefix="c" about? And what is <c:? Is it created due to the prefix ="c" declaration? –  swipe hard 13 hours ago
    
You can use custom jsp tags from custom taglibs in .jsp. In this example I'm using standard JSTL taglib. See tutorialspoint.com/jsp/taglib_directive.htm or tutorialspoint.com/jsp/jsp_standard_tag_library.htm for more info. –  daerin 13 hours ago
