how to insert value in a textfield using ajax and jsp
[nobr]Hi ,
I am new to ajax.My problem is that i cannot insert a value in to a textfield which is fetched from a database(MySql).
I have two jsp pages.Definition1.jsp and definition.jsp.
I am giving the code below.
Definition1.jsp
<html>
<%@ page language="java"%>
<%@page contentType="text/html" %>
<script language="Javascript" type="text/javascript">
function createRequestObject(){
var tmpXmlHttpObject;
if (window.XMLHttpRequest){
tmpXmlHttpObject =new XMLHttpRequest();
}elseif (window.ActiveXObject){
tmpXmlHttpObject =new ActiveXObject("Microsoft.XMLHTTP");
}
return tmpXmlHttpObject;
}
//call the above function to create the XMLHttpRequest object
var http = createRequestObject();
function makeGetRequest(wordId){
//make a connection to the server ... specifying that you intend to make a GET request
//to the server. Specifiy the page name and the URL parameters to send
http.open('get','definition.jsp?id='+wordId);
//assign a handler for the response
http.onreadystatechange = processResponse;
//actually send the request to the server
http.send(null);
}
function processResponse(){
//check if the response has been received from the server
if(http.readyState == 4){
//read and assign the response from the server
var result2 = http.responseText;
var result = http.responseXML.documentElement;
//do additional parsing of the response, if needed
//in this case simply assign the response to the contents of the <div> on the page.
document.getElementById('description').innerHTML = result2;//[b]this works correctly[/b]
alert(result.getElementByTagName('p')[0].childNodes[0].nodeValue);//nothing happends here
document.getElementById('name').value=result.getElementsByTagName('p')[0].childNodes[0].nodeValue;
[u][b]//above code does not works and this is my problem[/b][/b[/u]]
}
}
