[madhuri kunchala]

hi,
i tried to check data in xml file by using Ajax...i tried to enter the value which is already present in xml file...it is not showing any error..can any one help me out..here is the code...waiting for the reply...

function validate()
{
if (document.frm.id.value == "")
{
alert("Enter Package Name");
document.frm.id.focus();
return (false);
}
chkId=/^[WAP_]{4}\d{2}$/;
if (chkId.test(document.frm.id.value))
{}
else
{
alert('Invalid \"Pack Name\" Entry');
return false;
}
if (document.frm.act.value == "")
{
alert("Enter Activation Status");
document.frm.act.focus();
return (false);
}
chkAct=/^[MA]{2}\d{2}$/;
if (chkAct.test(document.frm.act.value))
{}
else
{
alert('Invalid \"Activation Status\" Entry');
return false;
}
if (document.frm.deact.value == "")
{
alert("Enter De-Activation Status");
document.frm.deact.focus();
return (false);
}
chkDeact=/^[MD]{2}\d{2}$/;
if (chkDeact.test(document.frm.deact.value))
{}
else
{
alert('Invalid \"De-Activation Status\" Entry');
return false;
}
if (document.frm.allwpp.selectedIndex < 0)
{
alert("Select one of the \"Allow Post-Paid or Not\" options.");
document.frm.allwpp.focus();
return (false);
}
if (document.frm.allwpp.selectedIndex == 0)
{
alert("Select \"Allow Post-Paid or Not\" option.");
document.frm.allwpp.focus();
return (false);
}
if (document.frm.shrt.value == "")
{
alert("Enter Package Name");
document.frm.shrt.focus();
return (false);
}
return true;
}
function trim(stringToTrim)
{
return stringToTrim.replace(/^\s+|\s+$/g,"");
}
function login()
{
if(validate())
{
xmlHttp=GetXmlHttpObject();
if (window.XMLHttpRequest)
{
req = new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
req = new ActiveXObject("Microsoft.XMLHTTP");
}
var id =document.getElementById("id").value;
var url="/xmlgprs/login.xml";
url=url+"?id="+id;
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true);
xmlHttp.send(null);
}
}
function stateChanged()
{
if (req.readyState == 4)
{
if (req.status == 200)
{
parseMsg();
}
else
{
alert("Unable to retrieve");
}
}
}
function parseMsg()
{
response = req.responseXML.documentElement;
var node = response.getElementsByTagName(id);
var chkNode;
var chkNode1 = chkNode.equals(node);
idArray = new Array();
for(var i=0;i<chkNode1;i++)
{
var node1 = node.item(i);
idArray[i] = node1.text;
}
viewElement();
}
function viewElement()
{
alert("valid");
}

Thanks in advance,
madhu.

And please post only the relevant code: most of this is form element validation, which has nothing to do with XML.

And I tell you what: the first time a form makes me submit multiple times for multiple validation errors, I'm off the site, because they don't care enough about me to do it right.

And for goodness sake, refactor :(

And use a JavaScript library--doing Ajax "by hand" is pointless.

And huh?

var chkNode;
var chkNode1 = chkNode.equals(node);

hi,
i had done validation by using Ajax..it is working fine..the problem...if i enter another value it is not getting added to xml file...can any one check it and help me out..waiting for the reply...here is the code...

function validate() {
if (document.frm.id.value == "") {
alert("Enter Package Name");
document.frm.id.focus();
return (false);
}
chkId = /^[WAP_]{4}\d{2}$/;
if (chkId.test(document.frm.id.value)) {
} else {
alert('Invalid \"Pack Name\" Entry');
return false;
}
if (document.frm.act.value == "") {
alert("Enter Activation Status");
document.frm.act.focus();
return (false);
}
chkAct = /^[MA]{2}\d{2}$/;
if (chkAct.test(document.frm.act.value)) {
} else {
alert('Invalid \"Activation Status\" Entry');
return false;
}
if (document.frm.deact.value == "") {
alert("Enter De-Activation Status");
document.frm.deact.focus();
return (false);
}
chkDeact = /^[MD]{2}\d{2}$/;
if (chkDeact.test(document.frm.deact.value)) {
} else {
alert('Invalid \"De-Activation Status\" Entry');
return false;
}
if (document.frm.allwpp.selectedIndex < 0) {
alert("Select one of the \"Allow Post-Paid or Not\" options.");
document.frm.allwpp.focus();
return (false);
}
if (document.frm.allwpp.selectedIndex == 0) {
alert("Select \"Allow Post-Paid or Not\" option.");
document.frm.allwpp.focus();
return (false);
}
if (document.frm.shrt.value == "") {
alert("Enter Package Name");
document.frm.shrt.focus();
return (false);
}
return true;
}
function trim(stringToTrim) {
return stringToTrim.replace(/^\s+|\s+$/g, "");
}
var xmlHttp = null;
function login() {
if (validate()) {

try {
// Firefox, Opera 8.0+, Safari
xmlHttp = new XMLHttpRequest();
} catch (e) {
// Internet Explorer
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
var id = document.getElementById("id").value;
var url = "/xmlgprs/login.xml";
url = url + "?id=" + id;
xmlHttp.onreadystatechange = stateChanged;
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
}
function stateChanged() {
if (xmlHttp.readyState == 4) {

parseMsg();
} else {
alert("Unable to retrieve");
}

function trim(stringToTrim)
{
return stringToTrim.replace(/^\s+|\s+$/g,"");
}
function parseMsg() {
var id = document.getElementById("id").value;
response = xmlHttp.responseXML.documentElement;
var node = response.getElementsByTagName("PACK_NAME");
//Na=Node();
//Na.toString()
// alert(node.length)
//ele=Element()

//ele.nodeValue
for ( var i = 0; i < node.length; i++) {
var node1 = node.item(i);
var childNodes=node1.childNodes;
for ( var j = 0; j < childNodes.length; j++) {
var childNode=childNodes.item(j);
if(childNode.nodeType == Node.TEXT_NODE){
alert(childNode.nodeValue);
if(trim(childNode.nodeValue) == trim(id)){
alert("already Present");
break;
}
}
}

//idArray[i] = node1.text;
}


}

I'd really rather not have to keep saying that :(
