how to access the jsp array variable into javascript? -


i want access jsp array in javascript. how possible?

jspcode

<%! string s[]; %>  <% list l=(list)request.getattribute("listresource"); system.out.println("the elements in list::"+l);  if(l!=null) {     system.out.println("the size of list::"+l.size());     int siz=l.size();     iterator itr=l.iterator();     while(itr.hasnext())     {         s=new string[siz];         int i=0;         s[i]=itr.next().tostring();         system.out.println("the elments are:"+s[i]);         i++;     } } %>

javascriptcode

function verify_details() {     var resourceid=document.getelementbyid("res").value;     var rid=new array();     rid=<%=s%>     alert(rid[0]);    }

i tried not getting values.

jsp code executed @ server side, , generates text. of text happens javascript code. javascript code executed @ client side, java array doesn't exist anymore data structure.

when write 

rid=<%=s%>

you're asking generate following string : "rid=" + s.tostring()

s being string array, generated javascript code : 

rid=[ljava.lang.string;@1242719c

and not valid javascript code.

javascript code, when you're generating jsp, not different html code. if want generate code rid = ['a', 'b', 'c']; string java array containing "a", "b" , "c", need iterate through java array , output single quote followed current string followed single quote followed comma. additionnally, should escape each string transform quote character \', newline character \n, etc. use stringescapeutils.escapejavascript commons-lang that.
