I have a form in JSP.
When I check any 3 checkboxes and submit the form I want the checked checkboxes to retain their state.
How to achieve this using javascript ?


<html>
<body>

<form action="">
<input type="checkbox" name="axes" value="Time">Time<br>
<input type="checkbox" name="axes" value="Product">Product<br> 
<input type="checkbox" name="axes" value="Location">Location<br> 
<input type="checkbox" name="axes" value="Sore">Store<br> 
<input type="submit" value="submit">
</form>

</body>
</html>

Please try this code.
<%@ page import="java.util.*" %>
<html>
<body>
<% 
   String[] axes = request.getParameterValues("axes");
   if (axes != null) 
   {
   	  String check = "checked='checked'";
      List list = Arrays.asList(axes);
	  if(list.contains("Time"))pageContext.setAttribute("time", check);
	  if(list.contains("Product"))pageContext.setAttribute("product", check);	
	  if(list.contains("Location"))pageContext.setAttribute("location", check);
	  if(list.contains("Store"))pageContext.setAttribute("store", check);		 
   }
%>
<form>
<input type="checkbox" name="axes" value="Time" ${time}/>Time<br>
<input type="checkbox" name="axes" value="Product" ${product}/>Product<br> 
<input type="checkbox" name="axes" value="Location" ${location}/>Location<br> 
<input type="checkbox" name="axes" value="Store" ${store}/>Store<br> 
<input type="submit" value="submit">
</form>
</body>
</html>

It solved the problem but it would be more helpful to me from my project perspective if the solution is achieved using javascript.

When the client submits the form, he creates a new request. The Javascript values from the previous page are lost. To use Javascript, you would have to store the data somewhere. You could use cookies or use localStorage (HTML5). Look at
