There is a JSP page in which i have an ArrayList variable. I need these arraylist values(txt1 and txt2) in script tag.I have tried lots of combinations and googling but didnot succeed.

javascript function

function fun1()
{   
   // how to get arraylist values      
}

JSP page:

 <body>
       <%
           ArrayList<String> al= new ArrayList<String>();
           al.add("txt1");
           al.add("txt2");

           out.println("<input type=text id=" + al.get(0) + ">");out.println("<br>");
           out.println("<input type=text id= " + al.get(1) + ">");out.println("<br>");
           out.println("<input type=button id=btn1  value=click onClick=fun1(); > ");
       %>
 </body>

    Inside javascript you can use Scriplets very well

    Assume the list ‘arrayList’ is having [1,2,3,4] in java (JSP)

    you can get the array list by this

    function fun1()
{   
   var list = '<%= arrayList %>';
}

    if you print the variable list, it will be a string with value ‘[1,2,3,4]’

    You can then split this using Regex or simple string operation

    <body>
       <%
           ArrayList<String> al= new ArrayList<String>();
           al.add("txt1");
           al.add("txt2");

           out.println("<input type=text id=" + al.get(0) + ">");out.println("<br>");
           out.println("<input type=text id= " + al.get(1) + ">");out.println("<br>");
           out.println("<input type=button id=btn1  value=click onClick=fun1(); > ");
       %>
 </body>

<script>
 // try the script here
</script>
