code is:
index1.jsp(jsp file)
<%@ page language="java" contenttype="text/html; charset=iso-8859-1" pageencoding="iso-8859-1"%> <!doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=iso-8859-1"> <title>insert title here</title> <script type="text/javascript" language="javascript" src="a.js"> </script> </head> <body> <form method="post" action="hi"> test_id:<input type="text" name=testid onblur="mango1(this.value)"> test code:<input type="text" name="testcode" id="tc"> testname:<input type="text" name="testname" id="tn"> <br><input type="submit" value="submit"> </form> <div id="k"> no test name!</div> </body> </html> a.js(java script)
function mango1(testid) { alert("this mango1 "+testid); var xmlhttp; if(window.xmlhttprequest) { xmlhttp=new xmlhttprequest(); } else { xmlhttp=new activexobject("microsoft.xmlhttp"); } xmlhttp.onreadystatechange=function() { if(xmlhttp.readystate==4 && xmlhttp.status==200) { /*document.getelementbyid("k").innerhtml=xmlhttp.responsetext;*/ var item=xmlhttp.responsetext; document.getelementbyid("tc").value=xmlhttp.responsetext; document.getelementbyid("tn").value=xmlhttp.responsetext; } }; /*xmlhttp.open("post","hello?testid="+testid, true);*/ /*xmlhttp.open("post","hello?testid=", true);*/ xmlhttp.open("post","hi?testid="+testid, true); xmlhttp.send(); } hi.java (servlet getting response database)

package dao; import java.sql.*; import java.util.vector; //import beans.test; import dao.dbcon; public class testdao { public vector getname(string testid) { connection con=dbcon.getconnection(); system.out.println("got connection"); vector temp=new vector(); try { resultset rset=null; preparedstatement pst = con.preparestatement("select testcode,testname test test_id=?"); system.out.println("got control here"); pst.setstring(1,testid); rset=pst.executequery(); while(rset.next()){ temp.add(rset.getstring(1)); temp.add(rset.getstring(2)); system.out.println("got control here in loop"); } } catch(exception e) { e.printstacktrace(); } return temp; } }
use separator between
out.write((string) vec.get(0) + ","); out.write((string) vec.get(1)); when response use split split text , set both fields like
var responsetextvar = xmlhttp.responsetext; var item=responsetextvar.split(','); document.getelementbyid("tc").value=item[0]; document.getelementbyid("tn").value=item[1];
