javascript - Using onclick event to submit 2 parameters into a the same servlet -

i'm trying use submit button pass 2 parameters, userid , friendid, using jsp same servlet. able obtain friendid, however, not able obtain userid.

function anotherpageservlet(servletname) {      document.forms[0].method = "post";     document.forms[0].action = servletname;     document.forms[0].submit(); }  function anotherpageservlet1(servletname) {      document.forms[0].method = "post";     document.forms[0].action = servletname;     document.forms[0].submit(); }  <input style="color:#3333ff"         type="submit"         class="rsubmit"         value="<%= retrieving.getdisplayname()%> :"         onclick="anotherpageservlet('viewingfriendservlet?stringparameter=<%= session.getattribute("userid") %>'), anotherpageservlet1('viewingfriendservlet?stringparameter=<%=retrieving.getoid() %>')" > 

you need escape quotes:

onclick="anotherpageservlet('viewingfriendservlet?stringparameter=<%= session.getattribute(\"userid\") %>'), anotherpageservlet1('viewingfriendservlet?stringparameter=<%=retrieving.getoid() %>')" 

i'm not used jsp, in jsf rather assign values request-scoped bean , call function works bean, rather passing arguments directly.

edit:

define onclick functions first, call simple reference.

function servletfoo() {      anotherpageservlet('viewingfriendservlet?stringparameter=<%= session.getattribute("userid") %>');     anotherpageservlet1('viewingfriendservlet?stringparameter=<%=retrieving.getoid() %>'); } 

then in html:

<input ... onclick="servletfoo()" />
