I need to get the value of <%= id%> in jsp code [<a id=<%= id%> href="javascript:redirect()" >] in my javascript. I am calling a javascript redirect(),

How can I get the value of id in my javascript? This is my javascript.

function redirect(){
    var a = document.getElementById("id").value;  
    alert(a);   
 }

I need to get the value in javascript function and need to submit the page from javascript.

I am using struts2 framework.

If I understand the question correctly, you need to pass the value <%= id%> to your javascript function. you can do this by making the following changes to your code

change the javascript function to :

 function redirect(id){
    alert(id);    /* or any other processing you need */
 }

and attach redirect in the JSP as

<table>
     <tr>
         <td>&nbsp;</td>
         <td>
             <a href="javascript:redirect(<%= id%>)" >      
                    <%-- CHANGE MADE ABOVE -- %>

                 <img src=<%= s%> style="width:90px; height:90px;" />  
             </a>
         </td>
         <td>
             <p>Product Name  : <%= name %></p>
             <p>Product Price : <%= list.get(i).getProdPrice() %></p>
         </td>
    </tr>
</table>
