Send value to servlet with javascript

Question

hi everyone,

In my JavaScript function I do like this in order to redirect parameters to servlet:

var ids1=document.getElementById("projet").value;
document.location.href("http://localhost:8080/Opc_Web_App/ServletAffectation?ids1="+ids1);

and in the servlet I do the following to get Value:

String idprojet= request.getParameter("ids1");
System.out.println("le projet selectionné est :" +idprojet);

the problem that i didn't have the result of System.out.print in my screen; so in other terms the servlet didn't get the parameter.

I can not see the problem until now. Please help. Thank you.

Answer 1

It may be possible that

var ids1=document.getElementById("projet").value;

is returning nothing?

Also,

System.out.println(..)

prints into the console, or the terminal prompt, not the browser's page.. To output into the browser, use

 response.getWriter().println(..)
